How to Optimize Email Headers for Better Deliverability?
To ensure better deliverability, follow these guidelines:
Authenticate your emails using SPF, DKIM, and DMARC. Use a recognizable "From" name and email address. Avoid misleading or spammy subject lines. Ensure the "Return-Path" is configured correctly to handle bounce messages. Monitor the "Received" path to identify any delays or issues in email delivery.
