AMP content causes MPART_ALT_DIFF_COUNT SPAM warning

[FederalWayDave]

Hello,

I am encountering an issue where the AMP content is causing a SPAM Assassin warning:

MPART_ALT_DIFF_COUNT

BODY: HTML and text parts are different

I became aware of this when the email was sent and got massively flagged as SPAM.

I know the AMP tab is the issue, because when I remove the AMP content and preview the email, the warning disappears.

Has anyone else encountered this?

• Is there a work-around?
• Is this a Campaign bug?
• Is this an AMP bug?

I've run into the same problem. Often, AMP emails get marked as spam at a higher rate.

Working on a workaround with a few promising leads but nothing found yet.
