Aliases provide the ability to send from multiple email addresses within one ProtonMail account. You can change the order of priority for all of these addresses by dragging them into the order you want in the Address tab of your Settings. The address represented with the Main tag next to it is your default address that will be used for sending unless another is chosen from the drop down in the From field when composing your message.
Original ProtonMail Address(es):
The original ProtonMail address is the first email you signed up for ProtonMail with. If you joined ProtonMail prior to 2016, you will have 2 original ProtonMail addresses (@protonmail.com and @protonmail.ch). You will know they are your originals by looking to the right of them. If you do not see a link to Enable/Disable, this is your original ProtonMail address. These addresses are provided for your use free of charge. They are always enabled allowing you to easily send and receive encrypted email.
Aliases using “+”
ProtonMail offers the ability to receive mail from an unlimited number of aliases by using a “+” symbol after your username in your email address.
- Email address: email@example.com
- Alias: firstname.lastname@example.org
Just add a “+” after your username and before “@domain.com,” to create a new email address that will be delivered right to your existing inbox. For example, if your email is email@example.com, email sent to firstname.lastname@example.org will also be delivered to your inbox. Aliases are especially useful in conjunction with filters. You can automatically apply labels or sort mail into custom folders by creating filter rules for your aliases. Learn more about using filters.
Aliases that utilize “+” do not support custom display names, as addresses do below.
Additional ProtonMail Addresses
Adding additional unique email addresses to your existing ProtonMail account is a premium feature.
- Main account email address: email@example.com
- Additional email address in same account: firstname.lastname@example.org
Every premium account has the ability to add at least 5 additional addresses to their account, with the option to add as many as 50. To upgrade your account or to check how many addresses you have remaining, please see the Dashboard under the Settings of your account. You can add additional addresses to your account by upgrading.
To add additional ProtonMail addresses visit the Addresses tab and select Add ProtonMail Address.
This will display a pop-up that allows you to choose your desired username and domain, select Submit, and enter your Login Password.
Once you have selected your new email address, choose the key strength you would prefer, select Generate Keys.
To disable/enable an address, return to the Addresses tab and select the Disable link to the right of the address you would like to enable/disable. All addresses that are disabled do not have the ability to send/receive mail.
Please note: Additional ProtonMail addresses can be disabled/enabled; however, they can not be deleted from your account unless you contact our support. These addresses will remain reserved as if it were your original address. They also count toward your address quota seen in your Dashboard no matter if they are enabled or disabled.
Custom Domain Addresses
In addition to ProtonMail addresses, you can use your own custom domain as your email address. This is also a premium feature, that requires you to have full access to your domain’s console and the ability to modify it’s DNS records. Learn how to setup a custom domain here.
Once you have setup your domain you can add email addresses to your account using that domain. Visit the Domains section and select Add Address
Once you have selected your desired username you will set the key strength you desire. Please be sure to complete the Generate Keys step as addresses can not receive mail until their keys are created.
You can see if you address is missing keys by visiting the Addresses tab, if any address is missing keys it will be displayed as Missing Keys with an option to Generate Missing Keys.
You will see if your address was successfully created by returning to the Domains tab and checking the Status.
Only Enabled addresses in the custom domain section count toward your account’s address limit.
All custom domain addresses can be enabled and disabled. Only custom domain addresses that do not have any emails stored in your account (including your trash) can be deleted.
