Apple to Support BIMI in Native Mail Applications

Apple Mail recently announced BIMI adoption within its email applications in iOS 16 and MacOS Ventura. In September. Apple will become the most recent email client to support BIMI.

Why adopt BIMI?

BIMI gives email recipients more confidence in messages they receive and helps them avoid fraudulent emails by forcing senders to utilize new technologies to make email more secure.

BIMI gives marketers and businesses enhanced branding opportunities by attaching the company’s logo to verified messages in the inbox as a reward for adopting DMARC email security technologies. Your customers will trust your correspondence more and your brand will be enhanced.

What is BIMI?

BIMI, or Brand Indicators for Message Identification, is a DNS-based email technology that allows a company to specify a logo for inbox providers to display in an email client. Email providers, such as Gmail, Yahoo Mail, and now Apple Mail, can show this logo to their users in the subject line of certified messages from the sending company. If you receive a legitimate email from Yahoo!, for example, this logo will appear:

How do I get BIMI?

BIMI requires DMARC. Before you can get your logo displayed in Apple Mail’s inbox, you need to get your email fully DMARC compliant, then apply strict DMARC policies. Becoming DMARC compliant is a process, but it is very beneficial and strongly recommended. You need to know who is sending email on your behalf, ensure they are properly configured with both SPF and DKIM, and regularly monitor DMARC delivery reports to understand DMARC compliance.

Once your verified email sources are fully DMARC compliant, you can start enforcing stricter “Quarantine” or “Reject” policies with your DMARC configuration. Inbox Providers like Yahoo!, Google and now Apple Mail will only attach a BIMI logo to your email if the email is DMARC compliant and you have a “100% Reject policy”.

Monitoring Complaints to Improve Email Reputation

As marketers, we all use some sort of marketing list for our email campaigns. These are typically opt-in prospects or existing customers. Sometimes we acquire lists from 3rd parties or put a case study or some other thought leadership behind a registration wall to obtain new marketing contacts. Regardless of where we acquire the email address, it has a certain value to us. But does the correspondence have value to the recipient? If not, it can affect your long-term sending reputation.

CAN SPAM

Before the CAN SPAM Act, end-users were inundated with junk email. This forced Inbox Providers like Google, Yahoo!, Hotmail and others to implement Junk and Spam filters to keep email at least somewhat relevant for their users. With the Act, marketers were now made responsible for policing their lists and removing anyone who opted out or unsubscribed. It’s an imperfect solution for several reasons:

  • Bad actors can completely ignore CAN SPAM.
  • Legitimate marketers can get email addresses from many sources, including the user, so the Inbox Provider cannot block unsolicited email.
  • Legitimate emailers can still “spam” a user with large amounts of irrelevant email unless that email user unsubscribes.
  • Unsubscribe methods may be complicated enough that users find it difficult and give up.

For these and many other reasons Inbox Providers have developed their own mechanisms to fight irrelevant email, spam and junk. These analyses can derail even well configured emailing domains.

Proprietary Junk and Spam Algorithms

Google, Yahoo!, Outlook.com/Office365.com, McAfee, Symantec and many other providers of inboxes or email gateway filtering software have come up with many ways to separate the valuable correspondence from the junk, spam and dangerous:

  • Blacklists – If the sending IP is on a blacklist, it’s probably spam. There are dozens of reasons for blacklisting, which includes being flagged as spam somewhere.
  • SPF Authentication – If the sender’s servers aren’t listed in the SPF record for the sending domain, it might be spam.
  • DMARC – If the sending domain fails, SPF checks or DKIM checks, then it might be spam. Our Delivery Center product started out as a DMARC compliance tool.
  • Attachments – Most inbox providers scan attachments for known malware and discard infected messages.
  • Subject Lines – There are certain subject lines typically used in spam and junk. These are easily filtered out.
  • Content – Content quality is an emerging issue for inbox providers. For example, dollar signs “$” or frequent use of FUD phrases might indicate spam. You can find more information about Content with our Inbox Placement tool.
  • User Feedback – Users provider direct and indirect feedback on relevance of a sender.

User Complaint Metrics Affect Email Delivery

Aggregating User Complaints is a great method for Inbox Providers to understand sending domain relevance across all their inboxes and discover emerging threats to their users. For example, your domain sends a legitimate marketing campaign and the Inbox Provider see the following:

  • ~20% of recipients open the email (based on global average open rates, yours may differ)
  • Some open the email and delete it without really reading it, indicating low engagement.
  • Some delete the email without opening, indicating apathy or disinterest.
  • Some mark it as spam or junk and even why they think it’s junk or spam.
  • Some click on your unsubscribe link, which can be tracked.
  • Some unsubscribe through the provider UI.
  • Some go to disused or invalid email addresses.

Do you know what these numbers are for your domain? Inbox providers are rating the deliverability of emails from your domain taking these new factors into account.

What can Marketing Do?

The good news is that Inbox Providers are willing to share your deliverability information with you! Called Complaints or Feedback Loops, Inbox Providers enable legitimate domains to subscribe to the complaints they receive from their users. Complaint detail can be:

  • The number of complaints received.
  • Email subjects that resulted in Unsubscribes, Spam Complaints or were marked as Junk.
  • Email addresses that bounce or were invalid.
  • Email addresses that unsubscribed at the Inbox Provider level.
  • Email addresses that marked emails as Junk or Spam.

Marketing can then:

  • Review campaigns that have a high complaint volume to improve them and make subsequent campaigns better.
  • Remove bounced and invalid email addresses from email lists. They’re wasting money and hurting your sender reputation.
  • Unsubscribe customers from marketing lists if they complained or unsubscribed. These complaints hurt your domain’s sending reputation and impact how your customers view your brand.

MxToolbox Can Help!

Our Delivery Center suite of email delivery tools now includes Recipient Complaints: aggregation, analysis and actionable insight that integrates with the top Inbox Providers’ feedback and complaint loops. Getting each Complaint/Feedback Loop integration setup can complicated, so MxToolbox Experts have created a simple, step-by-step guide for each integration: Yahoo!, Google, Validity, Mailgun, Microsoft and others.

Google’s Recent SMTP Relay Exploit and DMARC Policies

In April, Google began to see an uptick in spoofing attacks that utilized their SMTP Relay system and compromised Google accounts. They have closed the loophole by May, however, at least 30,000 malicious emails were detected in a two-week period. While this is an extremely small chunk of Google’s email traffic, similar exploits can affect other outbound email providers, requiring patches and constant vigilance.

What is the SMTP Relay exploit?

Google has a great reputation as an outbound sender so email coming from their servers is generally accepted. Google allows their customers to leverage that reputation to send bulk or large quantities of email through the SMTP Relay connection. Before the fix, this enabled any Google customer to send email that looked like another Google customer by simply putting their domain in the “From:” field. For example, SmallCompany.com gets hacked by a scammer and begins to send email that looks like GreatBrand.com, a well respected company also hosted at Google.

  • Blacklists – Google rotates sending IP addresses to minimize the affects of blacklists so a blacklist will not generally catch this issue.
  • SPF Authentication – Both SmallCompany.com and GreatBrand.com have Google’s servers in the SPF record, so it passes Authentication. This might be enough to make the inbox.
  • SPF Alignment – The “From:” address says GreatBrand.com. The <ReturnPath> is SmallCompany.com so it fails SPF Alignment.

So, unless the recipients servers are configured to check SPF Alignment, the Spoofing email may make the inbox. Any brand could then be compromised by a hack to another company in the same outbound email provider.

How do you protect your brand from spoofing?

First, you might think to bring all email in-house. This just compounds your risk. Google and other outbound email providers have more security experts and experience than even most large companies can ever hope to bring to bear. A small or medium business should leverage that experience to protect their brand and get their emails delivered.

Second, adopt DMARC and SPF, and DKIM. A properly configured SPF, DKIM and DMARC setup will help prevent spoofing of your brand and give you insight into potential spoofing issues.

Finally, adopt DMARC “Reject” policies. A DMARC “Reject” policy instructs recipient providers to highly scrutinize in-bound email and reject anything that fails SPF Alignment or Authentication. A “reject” policy would immediately fail email that arrived using the recent SMTP Relay exploit.

Why are few companies adopting “Reject” Policies?

If “reject” policies are great, why aren’t companies adopting them immediately? Unfortunately, there is a lot of fear and misunderstanding about “reject” policies. Our Experts receive push-back every day from our clients. Let’s look at a few examples:

“My legitimate email might be rejected”

While it is possible for legitimate email to be rejected, it is far more likely to be accepted if you have a “reject” policy in place. Inbox providers are looking for relevant content from senders with good reputations. By telling setting up DMARC with a “reject” policy you are telling them that you value your reputation. In addition, the “reject” policy is telling them to throw out emails that might harm your reputation.

“I won’t know if a legitimate source comes online”

Maintaining good email delivery means ensuring that all your legitimate email sources are managed actively. Each source should be included in your SPF record to ensure SPF Authentication. While it is possible for a department to bring in a new 3rd party email source without telling you, these vendors will have detailed information about proper SPF configuration as part of their on-boarding process. If it still slips by, then is it really valid email? Could that rogue department be hurting your brand? Regardless, a comprehensive DMARC reporting tool, like MxToolbox Delivery Center, will alert you that a potential Verified Email Source is missing.

“I won’t know if a phishing attack occurs”

The beauty of DMARC is that by publishing a DMARC record with RUA and RUF tags, you are asking for information about the compliance of emails that come “from” your domain. Inbox providers will tell you through an XML email report. Regular reviews of these reports will give you insight into legitimate sources that fail as well as emerging email threats from phishing attacks using your brand. While you can manually parse these XML files, most companies rely on a reporting tool, like MxToolbox Delivery Center, to process and distill these files into actionable insights.

“It seems complicated…”

While it can take some time to verify your outbound email sources, ensure that SPF and DKIM configurations are correct and monitor DMARC reports to ensure that everything is properly tuned, moving to a “reject” policy is not very complicated. MxToolbox Delivery Center uses our experience with DMARC to make recommendations on when to move to a “quarantine” or “reject” policy and how much of your mail to send under that policy.

If you still find it complicated, you can leverage our Expert Managed Services to help you with your configuration.

What do MxToolbox Experts recommend?

Our team of Experts is always evaluating the newest email technologies – DMARC “reject” policies are a necessity to help improve your brand reputation by stopping phishing attacks using your brand. If more brands adopted DMARC “reject” policies, phishing attacks would be greatly reduced. It’s time for all companies to be DMARC compliant – Get Started Today!

It’s time to adopt MTA-STS

Inbox Providers like Google, Yahoo! and Outlook.com are in a constant arms race trying to protect their users from spammers, spoofers and irrelevant content. Since the late 90’s dozens of new technologies have been proposed and adopted, including: Blacklists, TLS Encryption, SPF, DKIM, DMARC, BIMI and, now, MTA-STS. With the continued progression of MTA-STS, it is now time for all domains to adopt the technology to secure inbound email and reduce the threat of spam.

What is MTA-STS?

MTA-STS is an update to TLS Encryption that allows an Inbox Provider to specify a list of secure servers to receive email and mandates a secure TLS connection to these servers. Insecure connections will not be accepted. This corrects a few of the short-comings of TLS alone: Expired TLS Security Certificates, Man-in-the-Middle Attacks and attacks that downgrade to no encryption.

How does MTA-STS Work?

When a sender wants to connect to an inbox provider or domain’s email servers to deliver email, they first query the MTA-STS DNS entry which contains the location of a policy file. The policy file is accessed via HTTPs and contains information about the correct servers to use, which must match the MX records exactly, the TLS encryption requirements, the MTA-STS policy mode and the maximum length to cache this information. Senders then encrypt communication with the servers and transmit the email.

Since the sender is required to verify the connection and it is encrypted to known servers, the sender has a slightly higher level of trust. Any sender that fails this mini test can be considered a threat.

What does MxToolbox recommend?

MxToolbox recommends that all companies setup MTA-STS for their receiving domains to inform senders that their email servers and providers accept secure message delivery using SMTP over TLS and also require that email should not be delivered using an insecure SMTP connection. When MTA-STS is enabled for your receiving domain, it requests external servers to send messages to your domain only when the SMTP connection is authenticated with a valid public certificate AND encrypted with TLS 1.2 or higher. This is a higher level of security for incoming email and should reduce spam to your domain.

In addition, you should ensure that all your domain’s email senders support MTA-STS. This includes your email server software, email marketing, and any other potential email senders: CRM, Order Management, Support, etc. Once you select a provider’s MTA-STS policy, messages sent from your domain to external servers will also comply with the standard and improve delivery.

Does your email make it to the Inbox?

Inbox Providers are constantly adapting their algorithms to detect and eliminate spam while simultaneously elevating wanted email. This arms race puts Email Marketing at a disadvantage – we typically only receive a few data points:

  • # of Sent Emails
  • # of Emails Opened
  • # of Click-Throughs

While these leading indicators of sales are very valuable, they miss out on two key details:

  • Was the email delivered at all?
  • Was the email delivered to the Inbox or Spam/Junk Folder?

If you can’t answer those questions, then you may be missing out on simple methods to improve sales! Every email that fails to make the inbox is a conversation that did not happen!

The Flavors of Successfully Delivered Email

Email delivery is a complicated thing. There are multiple layers of technology protecting an inbox at modern inbox providers like Google, Yahoo! and Outlook.com. For example:

  • Blacklists are used to identify IP addresses that have spammed or otherwise should not be trusted
  • SPF identifies legitimate sending IP addresses for a domain
  • DKIM allows a domain to sign email to ensure the integrity of the email
  • DMARC enables a sending domain to get feedback from Inbox Providers on SPF and DKIM compliance
  • Inbox Providers maintain internal Unsubscribe Lists
  • Inbox Providers maintains internal Spam Lists
  • Inbox Providers run proprietary Spam Content Analyses
  • Inbox Providers monitor engagement with emails from a domain

Email Delivery Standards

Technically Delivered

In the email world, a message is considered successfully delivered when the recipient can access the email. The email could be delivered to any subfolder for example:

  • Junk
  • Spam
  • Quarantine
  • Bulk
  • Promotions
  • Customer configured Filter or Subfolder

While this does not seem optimal to the recipient or sender, the email is accessible, just not in the main Inbox.

Undelivered email is completely inaccessible to the recipient. An email could be undelivered for multiple reasons, depending on how the Inbox Provider’s algorithms work:

  • The sending IP was blacklisted so the system declared the email Spam and rejected it.
  • The Sending IP was not listed in the Sending Domain’s SPF record. This is either a misconfiguration or a sign of a deliberate spoofing attempt.
  • The DKIM signature does not align with the Sender’s signature.
  • The recipient mailbox is full
  • The recipient mailbox does not exists

Marketing Delivery Success

Marketers only see email delivery as getting the email to the recipient’s Inbox. That makes sense as their mission is only accomplished when the email is Opened, Read and relevant links Clicked.

Obviously, there’s a bit of a disconnect between how IT sees delivery and how Marketing sees delivery. Both are correct for their purposes. They are simply not speaking the same language.

MxToolbox Helps you Reach the Inbox!

MxToolbox has long developed tools and services around Mailbox Delivery. Our early Delivery Center service focused on the primary technologies supporting email delivery: Blacklisting, SPF, DKIM and DMARC. Our newest features of Delivery Center change this focus to help the Marketer reach the Inbox.

Complaints

Inbox Providers often have a list of complaints leveraged by their users against Senders. Some even allow access to these complaints, which often include email reported as spam, dead email inboxes, full inboxes and even unsubscribes done only through the Inbox Provider. Delivery Center now includes a feature to integrate and aggregate complaints and make them visible and actionable for you to improve your sending reputation with Inbox Providers. Lowering your complaints goes a long way toward making your email deliverable to the Inbox. Learn more about Complaints.

Inbox Placement

Ultimately, Marketing looks at metrics like Open Rates, Click-through Rates and Purchases to judge an email campaigns strength. However, these indicators lag something more important: Placement in the Inbox. Delivery Center now contains a tools that enables you to test the inbox placement of an email campaign both before sending it to your customers and simultaneously with the bulk emailing. Inbox Placement works across the large Inbox Providers like Google, Yahoo and Outlook.com. Learn more about Inbox Placement.

Two-Factor Authentication and Security

Security is important for any system you use, but doubly important for communications systems like email. Think about what you store in your inbox:

  • A history of all communications with important clients, friends and family
  • Irreplaceable documents
  • User ID for other accounts
  • Purchase histories at online retailers

There are probably many more things in there that you don’t want anyone else to access. It is therefore important that your email provider take precautions to safe guard your email.

Good Password Technique

Protecting valuable, private data requires good password discipline. MxToolbox has a few suggestions for passwords to improve security:

  • Do not make the password a “word” or derived from a word – The more random characters, the harder it will be for a password dictionary to crack it through guesswork
  • Do not reuse passwords – Unfortunately, site breaches and bad password file controls have exposed millions of passwords. If you reuse a password that was exposed, you are just asking for a hacker to gain access to your account.
  • Use a Random Password Generator – The more random a password, the harder it is to crack. MxToolbox has offered a free, untracked random password generator for several years.
  • Use a Password Vault – A password vault stores all of your passwords in an encrypted state that only requires a single password to access. It’s easier to remember a single, long password so a password vault takes the load of all those lengthy, random passwords for you.
  • Use Two-Factor Authentication where available

What is Two-Factor Authentication (2FA)?

Passwords are simply insufficient to protect important information. A simple password can be guessed, a password file could leak, etc. Many online companies are implementing Two-Factor Authentication to provide an additional layer of protection to sensitive information. Two-Factor Authentication, or 2FA requires a password and a code or token sent to a trusted device.

Two-Factor Authentication is common for Apple, Google and many other major website users. For example, an Apple user would see a warning on their iPhone about a sign-in to their iCloud account on an iPad or Apple computer and require using that code on the account. Google uses a similar approach through a Google Authenticator app on your phone or device. Other websites will send a text message with an authentication code that you input into the site to verify your login attempt. Regardless of the implementation, 2FA helps to ensure that the login attempt is valid by requiring access to a trusted device meaning that a hacker would have to have both the login and the device to gain access to the account.

MxToolbox Offers 2FA

MxToolbox has implemented Two-Factor Authentication across all our services. Email is the life blood of many organizations and we feel that it is important to protect our customers from potential breaches that might expose sensitive information. We highly recommend that every customer turn on 2FA for their account.

How to configure 2FA at MxToolbox

  1. Log in to your account.
  2. Click “username@mxtoolbox.com” in top right corner for dropdown menu.
  3. Click “Settings” option directly below username.
  4. Click “2 Step Verification” tab (fourth tab in header).
  5. After reading the explanation, choose either Software Token (recommended), Test Message, or Disabled and follow the instructions specific to your preference.
  6. If you see Status: Enabled to the far right of the Two-Factor Authentication (2FA) heading, you have completed MxToolbox’s 2FA process.

By utilizing 2FA, a potential compromise of just one of the two factors will not unlock your MxToolbox account. So, even if your password is stolen or your phone is lost, the chances of someone else having your second-factor information is highly unlikely. If you utilize 2FA correctly, websites and apps can be more confident of your identity and allow you secure access to accounts.

Super Bowl LVI and Email Security

Super Bowl LVI in California is almost upon us, and for millions of NFL fans around the world, it’s the most exciting time of the year. Unfortunately, it’s also a great opportunity for online and offline fraud. Every year, there is a new announcement of a ticket scam or a fraudulent merchandise.

While Email Security might not be on the minds of fans or businesses preparing for the big game, it should be. Email is still number one vector for starting a hack, cyber attack or online scam. Email is one of the easiest (and cheapest) ways to distribute a message and reach an audience. For legitimate businesses, email is also one of the easiest ways to make a mistake, caught in spam traps and have you message lost. For scammers, this is the opportunity to strike with intricate phishing and spoofing campaigns.

How do Email Settings affect Security?

Email security settings, specifically SPF and DMARC records, are both key to reaching your customers and preventing your brand from being exploited by fraud and phishing attempts.

SPF allows a domain owner to declare what IP addresses are legitimate senders of email for that domain. Inbox Providers check SPF records as part of delivering email that is sent from your domain. Spoofers can easily fake sending email from your domain, but if there servers are not in your SPF records then it will fail the Inbox Provider’s checks. Correct SPF records are therefore a minimum security precaution.

In addition, your domain’s DMARC record can tell an Inbox Provider like Google, Yahoo! or Outlook.com how to treat a particular email. There are three security levels to DMARC:

  • None, meaning accept all email from my domain even if it fails SPF and DKIM checks. This has the lightest level of security for your domain and allows Spoofing and Phishing attempts to make it to your customers’ inboxes.
  • Quarantine, meaning segregate emails that fail SPF and DKIM checks to a separate folder. This means that some email from fraudsters might end up in Spam or Junk.
  • Reject, meaning straight up reject any email that fails SPF and DKIM checks. This has the highest level of protection from fraud and phishing attempts, but may mean that occasionally legitimate email is blocked.

Reject policies are great, but do require regular review of your rejected email. We highly recommend that everyone adopt a “Reject” policy as soon as possible and allocate some time to reviewing rejected email for legitimate content, as well as outbreaks of fraud and phishing attempts thwarted by DMARC.

More information on DMARC tags can be found in our help tools here.

Top Ticket Vendor Domains

If you want to attend the Super Bowl in Inglewood, your best chance for buying a face-value ticket is to be a season ticket holder of an NFL team. If you’re not a season ticket holder, getting tickets will likely require going through 3rd-party sellers and brokers.

Some of the more popular and respected ticket supplier domains include:

While all of these have a minimum security posture of an SPF record, none have a Reject DMARC policy, setting them up for potential exploitation by scammers. Consumers may need to use extra caution when opening and interacting with emails that claim to be from most online Super Bowl ticket suppliers, especially if there are tell-tales of spam.

Let’s look at a few other related online suppliers…

Opportunities for Improvement

Unfortunately, it appears that many domains are not fully protected by SPF and DMARC records, meaning that consumer safety is up to the Inbox Provider and the consumer themselves. Email hackers and online scammers are ready to take advantage of any companies that aren’t safeguarded against attacks. The Super Bowl is just a single yearly event to exploit, but smaller businesses are also susceptible and less likely to recover. Adopting SPF, DKIM, and DMARC is both critical and inexpensive.

If you are a business owner, now is the time to improve your outbound email security by adopting SPF, DKIM and DMARC. It will improve your email delivery and safeguard your brand against Fraud and Phishing attempts.

If you are a consumer, businesses are slowly adopting DMARC, so until then, keep vigilant about the email you receive!

Roadrunner Emails are being targeted by Spammers

We have recently seen an uptick in complaints from Roadrunner Email users. It appears that many inbox users are receiving emails that appear to be from MxToolbox.com or use links back to mxtoolbox.com. The issue is appears to be that Spammers are using an Unsubscribe link that points to mxtoolbox.com. We are not sending these emails. We suspect that this is either a failure of DMARC email processing at RoadRunner or, more likely, an Inbox Provider Insider Scam.

How to recognize Spam, Fraud and Phishing attempts

We highly recommend everyone read our post on Recognizing Fraud and Phishing Emails, but here are a few key points:

Spam and Phishing Characteristics

  • There is a financial incentive or free product
  • There is an overwhelming sense of urgency
  • The origin is a company with which you have no connection
  • The subject line is strange or hyperbolic
  • You googled the company and that’s not the business they are in

If you think it’s spam or phishing?

  • Don’t open it unless you must 
  • Don’t click on any links
  • Don’t unsubscribe 
  • Mark it as Junk with your Email Provider

How DMARC affects email acceptance

DMARC policies instruct an Inbox Provider (think gmail.com, yahoo.com or rr.com) how to process email that fails to meet DMARC compliance tests. These tests include:

  • Determining if the sending IP address is designated by the sent from Domain – SPF Compliance
  • Determining if the send included a valid cryptographic signature in the email header – DKIM Compliance

If an email is DMARC compliant, then it may be sent from a legitimate sender. If not, then it could be considered spam. A “Reject” DMARC policy, like the one MxToolbox uses instructs Inbox Providers to reject any email that fails DMARC compliance tests. If an Inbox Provider is passing email from a non-compliant source despite a reject policy, this is a problem for their users.

What Inbox Providers should do

Inbox Providers generally pay attention to the DMARC policies of sent externally. They do this for two reasons:

  • Admitting non-DMARC compliant email increases the risks of spam email making it to their users. Blocking spam before it makes it the user is both a good security measure for users and a good selling point for the provider.
  • Admitting non-DMARC compliant email increases the costs of email storage. Each spam email is small, but take as a whole, they make up more than 50% of email traffic. Doubling storage is expensive if you don’t have to.

However, some Inbox Providers may only be looking at external email, and not email sent from other Inboxes in their network. This is a mistake that we call an Inbox Provider Insider Scam.

What Roadrunner users should do

We encourage any user receiving spam that appears to be from us to let us know! Contact Us on our site and include examples so that we can track down the issue.

You can also report the spam to Roadrunner, with the actual spam email so your admins can block the messages. Demand better inbox protection from your Provider.

Google to Fully Support BIMI

This week, Google finally announced the roll-out of BIMI across all Gmail inboxes. This is great news for email delivery and email security. BIMI will give recipients more confidence in the email they receive and force senders to adopt new technologies to make email more secure.

What is BIMI?

BIMI or Brand Indicators for Message Identification, is a DNS-based email technology that allows a company to post a logo for use by inbox providers. Inbox providers, like, Google, Yahoo! and Outlook/Office365.com, can show this logo to their customers next to certified messages from that company. If the email is not compliant with DMARC, then the logo does not show. Since it’s certified by being DMARC-compliant, your customers will know that the message is really from you and you will get your logo out in front of more customers and prospects!

How do I get BIMI?

BIMI requires DMARC. Before you can get your logo to appear in Google’s inbox, you first need to get your email fully DMARC compliant and then move to strict DMARC policies. Becoming DMARC compliant isn’t easy: you need to understand who is sending email on your behalf, have them properly configured with both SPF and DKIM and regularly monitor DMARC delivery reports to understand your DMARC compliance.

Once you have your verified sources of email fully DMARC compliant, you can start moving toward stricter “Quarantine” or “Reject” policies with your DMARC configuration. Once you set DMARC policy to “100% Reject” for non-compliant email, BIMI-compliant inbox providers will start appending your logo to email from your domain.
