Why email attachments fail

Most failures come from one of these:

  • File size exceeds mailbox limits.
  • Multiple attachments push total size over the cap.
  • The PDF includes large embedded images.

Compressing before attaching usually solves this in one pass.

Best workflow for readable email PDFs

Follow this approach to keep quality:

  • Start with medium compression, not maximum.
  • Check body text at 100% zoom.
  • Review image-heavy pages for blur.
  • Re-run with lighter settings if needed.

If your PDF is still too large, split appendices into a second file.

Target sizes you can use

Different providers have different limits, so use practical targets:

  • Under 10 MB: generally safer for broad compatibility.
  • Under 5 MB: better for faster sending and receiving.
  • Under 2 MB: ideal for mobile recipients and quick downloads.

Always verify final size before sending.

Before you hit send

Quick final checklist:

  • Attachment opens correctly.
  • Text remains crisp and legible.
  • Important charts and signatures are clear.
  • File size is within recipient limits.
