Description

Newsletter Office 365 Headers Removal is a WordPress plugin designed to clean outgoing email before it’s sent through your SMTP plugin. Its main purpose is to remove hidden or unwanted headers that can cause Office 365 SMTP servers to block messages or reject them during delivery attempts.

If your site uses Office 365 SMTP with an SMTP plugin and you’re seeing delivery issues, this addon helps reduce the likelihood of those blocks by stripping problematic headers from the email payload. The plugin is lightweight and easy to install, with a focus on seamless integration into your existing SMTP workflow.
