Attachments
Picked, pasted, or linked.
Attach with the paperclip or by pasting, and drop images into the body. Sent keeps a copy you can download again.
In short
What is an email attachment?
An attachment is a file carried inside the message, encoded as text beside the body. Every copy carries the whole file, so mail services cap message size and big files often travel as download links.
5MB
of files carried inside one message
2MB
above which a files domain sends links
100MB
per linked file, through the API
How it works
How it goes in decides where
The paperclip and paste attach files. A PNG, JPEG, GIF or WebP dropped or pasted into the body is embedded there. Other drops are ignored.
Small files ride along, big ones link
Files inside a message are capped at 5 MB together. On Automatic, the default, a set over 2 MB goes as links once a files domain is active.
Shrink images, or keep the originals
Low and Medium fit images inside 1920 × 1080. Original leaves them alone, and switching re-processes files already attached.
What the paperclip offers
The picker suggests these. Pasting attaches anything else.

Good practice
Getting the most out of it
- 01
Pick, do not drag
A drop only takes images, so use the paperclip for everything else.
- 02
Add a files domain
Automatic only swaps sets over 2 MB for download links once one is active.
- 03
Original for fine print
Low and Medium fit images inside 1920 × 1080, which can blur fine text in scans.
Where it stands
Good to know
- Big files from the composer
- Uploads still count against 5 MB. The 100 MB links are for workspace files, through the API.
- Downloads from Sent
- Mail sent before Sent kept copies, and files since deleted from Files, come back empty.
