Attachment size limit
You can send up to 25 MB in attachments. If you have more than one attachment, they can't add up to more than 25 MB.
If your file is greater than 25 MB, Gmail automatically adds a Google Drive link in the email instead of including it as an attachment. Learn more about Google Drive attachment sharing settings.
Attachments won't upload (desktop)
- Make sure that you're using a supported browser.
- Try adding the attachment in another browser.
- If you've set up a web browser proxy, try disabling it.
Attachments might be unavailable
Your network administrator or Internet provider probably blocked 'mail-attachment.googleusercontent.com', the domain that Google uses to host attachments.
For more help, contact your internet service provider.
Blocked for security reasons
To prevent viruses, Gmail doesn't let you attach executable files, such as files ending in .exe.
