What is a Catch-All email address?

Catch-All is currently only available for Visionary and Professional ProtonMail account holders.

Catch-All provides ProtonMail Custom Domain users the option to receive all mail sent to their domain, even if it was sent to an email address that has not been setup within their account.

Enabling Catch-All

  1. Ensure your have completed all of the steps to setup your custom domain and addresses.
  2. In the Domains tab within the Settings of your account, you will see all the addresses of the account listed.
  3. To enable Catch-All, check the box next to the address. All mail sent to your domain that does not match an address in your account will now be delivered to this selected address.

Catch All


If you do not have Catch-All enabled and a sender tries to send a message to an incorrect address, they will receive a bounce back message informing them that the address they tried sending to does not exist within that domain.

Your message wasn't delivered to wrongaddress@yourdomain.com because the address couldn't be found. Check for typos or unnecessary spaces and try again.

Tip: To ensure you do not clutter inboxes, we recommend creating a dedicated address (i.e. catchall@example.com or contact@example.com) within your domain to deliver all Catch-All messages to.

    Is there any possibility of this becoming a Plus feature? If not, a add-on for the Plus plan? I want the catchall, but I can only afford the Plus plan. Thank you!

    100% agree. Most comparable mail services have a catch-all (at least through some custom filter configurations) in the price range of the Plus plan. This is the only feature lacking from Plus that is holding me back from migrating to ProtonMail.
