MxToolBox Email Header Analyzer Makes Email Headers Readable

Our Email Header Analyzer has been around for a few years but we have recently polished it to include a few more cool features. Email Headers can be a real challenge to decipher which is why we developed this tool in the first place. In simple terms, it makes email headers as readable as the newspaper.  Email headers are present on every email you receive via the Internet and can provide valuable diagnostic information like mail server delays, anti-spam results and more.

So lets try out the tool and some of its new features. Simply grab some email headers (not sure how to get email headers?) and paste them into our tool here. To view the example below in a live format on our site, go here.

  1. Sharing – We have added sharing tools at the top of the page. Share with your IT Administrator, Support Department or Vendor to help with the troubleshooting process.
  1. Time Stamps – Visual graph that quickly shows the amount of time the message took at each server/hop. This view can help you see if if/where there was a delay at any of the servers.
  2. Server Hops – A more detailed look at the servers that touched the message, also includes delays in this format if applicable.
  3. Parsed Headers – Email Headers can be very confusing to read, so this part of the tool parses out the valuable information like Sender, Recipient, Date, Time, Subject of the message etc.
  4. Original Headers – Sometimes you need to refer back to the raw email header so we have put that information at the bottom.

Our website and its tools are constantly evolving and we would love to hear your feedback! Please let us know if you think something can be improved etc. Hit us back at

If you are concerned about mail delays or other performance issues with your server we would highly recommend trying our Premium MailFlow Monitoring. This service sends a message through your server and back to our datacenter. This unique method allows us to provide complete mail flow visibility on your server. This can help uncover issues that might be creating delays as well as detecting both inbound or outbound mailflow failures.  In addition to alerts for failure, you can login to see daily, weekly and/or monthly historical statistics. This method allows you to get a true picture of the performance of your mail server.
