Understanding email headers and spam detection
What are email headers and how do they affect spam detection?
Email headers are part of the email that contains information about the sender, recipient, and the path the email took. They play a crucial role in spam detection.
Headers can include domains or IP addresses that are blocklisted, which email filters use to mark emails as spam. By reviewing and ensuring these headers do not contain blocklisted resources, you can reduce the chances of emails being incorrectly flagged as spam.
