Files
Every attachment, in one list.

Search by name, filter by type, see what each file weighs and open the message it came on.

In short

Where do email attachments live?

An attachment is a file carried inside an email, encoded next to the text. The mailbox keeps it with that message, so finding a file usually means finding the email first.

How it works

Search the names, filter the type

Type part of a filename and the list narrows. Pick a type to cut it further.

What you sent counts too

A file you sent sits beside the ones that came in, with the address it left from and a link to its message.

Deleting takes the bytes

Only the owner can delete a file. The stored copy goes for everyone in the workspace, and the total drops with it.

What each type filter matches

Each filter matches the start of a file's content type, not its extension.

What you get

In the product today

Open or download

Any row opens the file in a new tab or saves it.

Counted, not capped

The total at the top adds up every file you can see.

Back to the message

Jump from a file to the thread it came on.

Only your addresses

On a shared mailbox you see files for the addresses granted to you.

Good practice

Getting the most out of it

  1. 01

    Name it before you send

    A file you send keeps its name here, so a clear one is easier to find.

  2. 02

    Narrow by type first

    Pick PDFs or images first, then a few letters of the name will do.

  3. 03

    Clear the heavy ones

    Filter to video to see what takes the room, and delete only what you keep elsewhere.

Where it stands

Good to know

A deleted file on its message
The thread still lists the attachment. Opening it fails like any missing file, without saying it was removed.
Older attachments
There is no backfill. The list fills as new mail arrives, and older files stay on their messages.

Works well with

Attachments

Pick them with the paperclip or paste them in. A pasted image lands in the body rather than the file list, and a file dragged onto the composer is not attached at all. On an OpenEmail mailbox incoming files sit in object storage, one object each, and opening a thread pulls every one of them.

Files on your own domain

Download links for the files you send on a subdomain you choose, such as files.yourdomain.com, instead of the OpenEmail address.

Scoped visibility

One address means one address.
