# Files on your own domain Your name on the download link.

Download links for the files you send can use a subdomain you choose, such as files.yourdomain.com. It takes one CNAME record.

In short

## What is a custom download domain?

Large files often travel as a download link rather than inside the message. A custom download domain puts that link on a subdomain of the sender's own domain.

2 MB

per message before files go as links on your domain

3

failed checks in a row before links fall back

2 hours

without a pass before links fall back too

How it works

## One record on the Files tab

The Files tab suggests files.yourdomain.com and shows one CNAME record to add at your DNS provider. On a domain connected to Cloudflare, Sync writes it for you.

## Active after a passing check

New download links carry the name once a check over HTTPS passes. Three failures in a row send them back to the OpenEmail address until one passes.

## Sent mail keeps its name

Links in mail already sent work while the old CNAME stays. On a domain connected to Cloudflare, a rename or removal takes it out and they stop working.

What you get

## In the product today

Any subdomain

Keep files.yourdomain.com or type any other subdomain.

Per sending domain

Any address on that domain uses it for download links.

No inbound needed

The ownership TXT is enough, before any mail arrives.

Downloads only

It serves files sent by its own workspace, nothing else.

Good practice

## Getting the most out of it

1. 01
   
   Plain CNAME, no proxy
   
   Add the record with any proxying turned off.
2. 02
   
   Leave the old record
   
   After a rename, keep the old CNAME so earlier links still download.
3. 03
   
   Check for Active
   
   Automatic only sends links once the status reads Active.

Questions

## Works well with

Tracking on your own domain

Tracked links and the open pixel on a subdomain you choose, such as links.yourdomain.com, instead of the OpenEmail address.

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.

Multiple domains

Point several domains at one inbox, subdomains included.
