Addresses and identities

If you subscribe to a Proton Mail(new window) paid plan, you can create additional email addresses, also known as aliases, which you can use instead of your free personal email addresses. And all Proton Mail users can create unlimited extra addresses, known as +aliases, by adding “+” after your username in one of your free personal email addresses.

Here we explain how to create and use aliases and +aliases.

Additional addresses (aliases)

If you have a paid plan, you can create at least 10 additional addresses (depending on your plan) with any Proton domain (@proton.me, @protonmail.com, @pm.me, or @protonmail.ch) or a custom domain(new window), if you have one.

How to create an additional address (alias)

1. Log in to your account (account.proton.me(new window)) and go to Settings → Go to settings → Identity and addresses → My addresses → Add address.

2. Add a new username and choose a Proton Mail or custom domain ending from the dropdown menu.

3. Add a display name.

How to enable, disable, and delete an additional address (alias)

1. Log in to your account (account.proton.me(new window)) and go to Settings → Go to settings → Identity and addresses → My addresses → Add address.

2. Choose Enable, Disable, or Delete from the dropdown Actions.

Please note:

  • If you disable an address, then it’s no longer active, so you can’t send and receive emails using it. Disabled Proton Mail domain addresses continue to count against your additional addresses limit, whereas disabled custom domain addresses don’t count towards the limit.
  • You can delete a custom domain address using the Addresses interface, but you can’t delete a Proton Mail domain address from here. If you want to delete a Proton Mail domain address, please contact our Customer Support(new window) team.
  • If your address is missing encryption keys or has been disabled, you can see it labeled as such in your list of addresses. The options to Enable or Add Keys will show up in the dropdown Actions menu.

How to use an additional address (alias)

All mail sent to an additional address will appear in your regular inbox by default. But you can use a combination of filters(new window) and custom folders and labels(new window) to organize your mail from different addresses.

For example, if Alice Jones had subs@alicejones.com as an additional address for all her subscriptions, she could set up a filter that automatically sorts mail to that address into a “Subscriptions” folder, or applies a “Subs” label.To send an email from an additional address, click anywhere in the From addresses field and select the address you want to use from the dropdown menu.

How to select your sender address in the dropdown from field

If you want to use an alias as your primary address, you can make it your default sending address:

1. Log in to your account (account.proton.me(new window)) and click Settings → Go to settings → Identity and addresses → My addresses.

2. Choose Make default from the dropdown Actions or drag and drop your chosen default address to place it at the top of the list.

This address will now automatically appear in the From field when you start a new message:

+Aliases

+Aliases are a kind of sub-email address that you can create by adding “+something” after the username in one of your free personal email addresses.

For example, Alice Jones (alicejones@proton.me) could receive emails sent to alicejones+bills@proton.me or alicejones+wedding@pm.me.

Note that you can’t compose new messages from scratch using +aliases, but you can reply using the +alias to messages sent to that +alias.

How to create a +alias

There is no need to create or set up a +alias in your user settings. Rather, a new alias is created whenever someone sends you an email to that +alias.

As any address with the correct “username+something” structure works as a +alias, you can have an unlimited number of +aliases for each of your free personal email addresses.

How to use a +alias

+Aliases have a number of uses. For example, you may want to post a +alias instead of your personal email address on your public website or social media accounts to help identify spam.

+Aliases are especially helpful for organizing your inbox in combination with filters. Like regular aliases, you can use filters(new window) to sort your mail from different addresses using folders and labels(new window).

For example, you could ask invitees to your wedding to respond to the alias username+wedding@proton.me. Then you can set up a filter to automatically apply the label “Wedding” to all mail sent to that alias.
