It’s Time for BIMI

For the last few years, we’ve been on the fence about when it would be time to implement BIMI. Often, it seemed like the ability to adopt BIMI would only be there for large companies with substantial email marketing budgets. However, support for both Common Mark Certificates as well as Verified Mark Certificates makes BIMI much more accessible for small and medium businesses. We now think BIMI is ready for everyone!

What is BIMI?

BIMI is a DNS technology that allows you to define a logo to appear next to your email subject lines or next to your messages in major Inbox Providers’ web-based, computer and mobile clients. Essentially, your mail will be branded with your logo giving you more exposure and potentially creating an edge over your competitors.

An example of the MxToolbox Logo displayed next to our email in Google’s web client.

Note: BIMI is different from simply being a GSuite-using company in that your BIMI logo will appear at Yahoo!, Le Post and many other web-based, computer and mobile email clients, not just the Google Inbox.*

How do you adopt BIMI?

To be BIMI compatible, you need to have your email configuration setup properly. Inbox Providers need a level of trust before they will include your logo as it appears to be an endorsement of sorts for your brand.

  • You must adopt DMARC, DKIM and SPF
  • Your email must be DMARC compliant
  • Your DMARC policy must be at 100% Reject
  • Your BIMI record must be setup correctly with a properly formatted SVG file
  • You must have a Common Mark Certificate or Verified Mark Certificate for your logo

How does MxToolbox help?

  • Setup SPF, DKIM and DMARC for your Domain
  • Carefully migrate to a DMARC Reject policy
  • Setup your BIMI record
  • Verify compatibility of your SVG image
  • Monitor your certificates for expiration
  • Manage the on-going changes to the BIMI standard

The Double-Edge Sword of Generative AI and Email

For most people doing creative marketing work, Generative AI can be a huge asset. You can write white papers, create tag lines for ads, and develop new email campaigns quickly and easily. But, there are downsides to all of this productivity…

Losing your voice

Your voice, your brand, your identity. Losing this is easy if you are not careful how you deploy generative AI. Generative AI has its own voice, so you need to apply your brand to it before deploying the content it generates. Make sure it uses your verbiage, your terms and reflects your brand. If you don’t, you risk blurring into the background noise from all the other brands deploying generative AI in their campaigns. While Google, Yahoo! and Outlook.com have not disclosed policies or filters looking for generative AI, they are at the forefront of the technology, so you can be sure they are!

Going All -In

It may seem like a good idea to ramp up your outreach programs, especially email, now that you have a virtually unlimited source of content. Unfortunately, that can make your email delivery worse. Higher volumes of email can trigger greater scrutiny at Inbox Providers like Google, Yahoo! and Outlook.com, which could make it more difficult to make the Inbox. Further, you could induce email fatigue in your recipients. Fatigued users are:

  • Less likely to open your emails
  • More likely to mark them as Spam
  • More likely to Unsubscribe

Rather than increasing the quantity of your interactions, you should be looking to increase the quality: Better content yields better results.

Generative AI Phishing

If you can use Generative AI to create content for your legitimate business, rest assured that spammers, scammers and fraudsters are already fully embracing the ability to generate huge quantities of malicious content. This means that it is even more important to educate your teams about phishing scams and improve your email security.

In addition, it is now more important to protect your brand from being used in phishing attacks by adopting a DMARC Reject policy. Adopting DMARC and setting your DMARC policy to Reject will tell Inbox Providers to trash any email that appears to come from your domain that is not DMARC compliant. This makes it harder for phishing scammers to send email that appears to come from your domain. DMARC reject policies also enable you to adopt BIMI, which will get your brand logo into the Inbox alongside your email.
