Email Attachments That Actually Arrive
Large or oddly formatted attachments get blocked or ignored. Here is how to send files that land and get opened.
Most email providers reject messages over about 25 MB, and many corporate servers set the limit far lower. A bounced attachment costs you a follow-up and, often, the reader's attention.
Send one PDF, not ten photos
Combine scanned pages or photos into a single document with JPG to PDF. One file is easier to open, print and forward.
Compress before you attach
Scans are often far larger than they need to be. Run them through Compress PDF and check that the text stays readable.
Name files for the reader
invoice-march-2026.pdf tells the recipient what they are opening. scan0001.pdf does not.
Link instead of attaching for big files
For newsletters and campaigns, host files on your site and link to them. It keeps messages light and lets you see who clicked.
