How to create and use an additional address (alias)

With ProtonMail, you can have at least two personal addresses free: 

  • One ending in (like, usually the original address you signed up with.
  • A short version of this address ending in (, which you can activate in Settings.

(If you joined ProtonMail before 2016, you also have a address.)

If you subscribe to a ProtonMail paid plan, you can also create additional addresses, known as aliases. And all ProtonMail users can create unlimited extra addresses, known as +aliases, by adding “+” after your username in one of your free personal email addresses.

Learn more about types of email addresses and aliases.

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 five additional addresses by default (depending on your plan), with any ProtonMail domain (,, or or a custom domain, if you have one.

How to create an additional address (alias)

1. In the ProtonMail web app, go to Settings → Go to settings → Identity & addresses → My addresses → Add address.

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

3. Add a display name.

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

1. In the ProtonMail web app, click Settings → Go to settings → Identity & 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  • If you disable an address, then it’s no longer active, so you can’t send and receive emails using it.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 ProtonMail 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 ProtonMail domain address from here. If you want to delete a ProtonMail domain address, please contact our customer support 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 and custom folders and labels to organize your mail from different addresses.

For example, if Alice User had 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 desired address from the dropdown menu.

List of aliases in the email From field

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

1. In the ProtonMail web app, click Settings → Go to settings → Identity & addresses → My addresses.

2. 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 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 User ( could receive emails sent to or

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 to sort your mail from different addresses using folders and labels.

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

    Greetings. If a user of the plus plan, has created 5 additional mail addresses, what will happen to them when the billing cycle end without renewal? I presume that the default address will downgrade to free plan, but the others? Will they be recyclable after a while? Even more, what will happen to them if the default address be deleted eventually, after has been downgraded, without any credit left? Thank you in advance.

  6. ProtonMail Support

    ProtonMail subscriptions are not downgraded to the free plan automatically and addresses are never recycled.
    If a user misses their payment, the account becomes delinquent until the invoice is paid.

    I have questions about aliases and how to create them. Also I seem to be reading conflicting information on your website.

    This sentence under the Addresses and Aliases section:
    “Aliases provide the ability to send from multiple email accounts within one ProtonMail account.”
    And this sentence under Creating a new Alias:
    “You can only use an alias to receive emails, not to send.”

    Also this sentence under Aliases, Addresses, and Users:
    “While free users can have unlimited aliases, adding addresses and users are only possible for paid plans.”
    Conflicting with the advertised “Up to 5 email aliases” under the PLUS plan when creating an account.

    All of this has left me more confused than when I started.

  8. ProtonMail Support

    The unlimited aliases referred to here for Free users are actually +alias addresses, for example:, and cannot be used to send messages, however, if you receive a message to a +alias address and reply to it, the +alias address will be displayed in the From field.

    On a paid plan, you can add additional addresses which can be used for both sending and receiving messages, and these addresses can be completely different from your original address. These additional addresses are sometimes also referred to as aliases in the sense that they share the same mailbox as your original address and do not have separate login credentials. Additional addresses can have a ProtonMail domain or custom domain.

    I have an Protonmail Plus account with three different addresses.
    I want to receive an email on my alias ex. but it doesn’t work.
    The sender account couldn’t find the address and the delivery is aborted.
    What I’m doing wrong?

  10. ProtonMail Support

    If this only happens with a specific sender, perhaps their system is not able to send to +alias addresses. Otherwise, there is nothing wrong with an address such as

    Can I use different addresses for different persons?

  16. ProtonMail Support

    For separate mailboxes, you will need a plan with multi-user support: Visionary or Professional with the appropriate number of users added.

    Greetings. Do 2 of the same new addresses in your 2 domains ( and count as 2 extra addresses or only as 1 extra address . Let’s say I make an extra address in my plus account “”, does “” again count as an extra address or do they count together as 1 extra address? Thanks you.

    Some website won’t let you register an email account with a + in it. Is there another way to do aliases using another symbol?

    Hello Brandon,

    Unfortunately, no, only +aliases are supported.
