What is MailAuth Analyzer

What are Email Headers?

Email headers are like the hidden backstage of an email. They contain important information about the email’s sender, recipient, subject, date, email authentication validation status for your emails, deliverability and alignment issues, etc. Although you usually can’t see them in your email client, they play a crucial role in how emails are delivered. 

While the raw file for your email headers can be difficult to read, our Email Header Analyzer tool parses your email headers in a human-readable format that helps you easily read and understand this information.
