“Gmail — Attachment Failed to Upload”
What This Means (In Plain English)

How to Fix It — Step by Step
- 1
Check the file size — Gmail has a 25 MB limit for attachments.
- 2
If the file is larger than 25 MB, Gmail will offer to use Google Drive instead — accept this option.
- 3
Check your internet connection.
- 4
Try attaching a smaller file to test if attachments work at all.
- 5
Close Gmail and reopen it, then try again.
- 6
Try sending the email from a computer instead of your phone.
How to Prevent This in the Future
Compress large files or use Google Drive for files over 25 MB. Make sure you have a stable internet connection when sending attachments.
