Fix Attachment and Message Size Warnings

Large emails are slower to process, more likely to be clipped, and easier to distrust.

Common warning triggers

  • Too many attachments
  • Large PDF or media files
  • Bloated HTML markup
  • Image-heavy templates

Safer alternatives

  • Host files behind a secure download page
  • Compress documents before attaching
  • Reduce inline asset weight
  • Keep the template focused on the action you actually want

The most deliverable email is usually the simplest one that still gets the job done.
