Before sending Gmail attachments, check the combined size and the account’s actual sending limit. A limit for each individual file is not permission to attach several files whose total exceeds the message’s allowance.
Attach the intended files and confirm completion
In computer Gmail, compose the email, choose the paperclip attachment control, select the files, and let the uploads complete. Check the displayed names carefully, particularly when several versions of a document have similar filenames.
Remove an unintended item with the control beside that attachment. Verify the remaining list before sending; a sentence saying “see attached” does not establish that the expected file was uploaded.
Use the limit for your account and interface
Google’s current personal Gmail guidance lists a 25 MB attachment limit. Work and school users should check their administrator’s configured limits and the applicable Workspace documentation.
The current Workspace sending table distinguishes editions and interfaces: it lists 25 MB for Business and Education, and up to 50 MB for Enterprise Plus on Gmail’s web version, with 25 MB for Enterprise Standard. Its table defines these values against total message content and attachments before encoding. Do not apply a larger web allowance to every account or mobile app.
Receiving limits are separate, and the recipient’s provider can impose its own conditions. File sizes on your computer also do not necessarily equal the final encoded email size. Leave a sensible margin instead of treating a close arithmetic total as proof of deliverability.
Inspect any Drive-link substitution
When the combined attachments exceed the applicable limit, Gmail can replace them with a Drive link. Check that the intended recipients have permission to open it; a successful email send does not automatically make a private Drive file readable.
For sensitive material, use the organization’s approved transfer method and the narrowest suitable access. Do not make a file available to everyone merely to avoid a size error. After sending, inspect the actual sent message so you know whether you delivered file copies or a link to a separately controlled resource.
