Transfer existing emails

Moving your mailbox to Proton Mail is quick and simple with the Easy Switch(new window) app.

Set up email forwarding

Update June 2020: Unfortunately, a Yahoo Mail Pro account is now required(new window) to enable automatic email forwarding in Yahoo Mail.

Once you’ve imported existing messages, continue with the setup of automatic forwarding. This ensures that all the new messages sent to your old Yahoo account also arrive in your Proton Mail inbox. Once senders learn your new Proton address, they can reach you directly at your Proton Mail address. 

Keep in mind that messages forwarded from Yahoo first go through Yahoo’s servers. This means they will only be TLS encrypted, and not end-to-end encrypted(new window), and Yahoo can access them.  

Here are 4 quick steps to forward your Yahoo messages to Proton Mail:

  1. Go to Settings in your Yahoo account and click on More Settings.
  2. Go to Mailboxes.
  3. Select the mailbox account you want to forward your email from.
  4. Under Forwarding, enter your Proton Mail address.
  5. Click Verify.

Transfer contacts

Proton Mail offers a private, secure space for all your contacts. You can create an encrypted contact list(new window) in just two steps: export to a CSV file and import it to Proton Mail.

To export your Yahoo contacts to a CSV:

  1. Open your Yahoo account.
  2. Click the Contacts icon.
  3. Click the More options icon.
  4. Click Export.

To import the CSV to Proton Mail:

  1. Open your Proton Mail account in a browser on your desktop.
  2. Select Import in the left menu on the Contacts page.
  3. Drop your CSV file in the box or click on the box to select the CSV.
  4. Select Import.

Inform your contacts 

Tell your contacts you are using a new email address. You could send out a short Proton Mail email to say hi and order a new set of business cards. 

Please keep in mind that Proton Mail imposes limits on the number of emails you can send at once to avoid spam and phishing attempts. The limits depend on many criteria, including the behavior of the sender.

To make this transition easier, you can share your short domain email address with your contacts. Emails received via appear in the same inbox as those using your address. All Proton Mail accounts, free and paid, can receive emails at this address, and paid accounts can use it to send emails too. 

For example, if your email address is, the associated email address is

Update online accounts

Connect your online accounts to Proton Mail to protect your sensitive communications, instead of using your Yahoo address as a point of contact. By migrating messages related to finance, health, and shopping to Proton Mail, you will avoid having this personal information used to profile you and potentially exposed or sold to third parties.

This has to be done on an individual account basis, so you can also use this opportunity to review your accounts’ security settings and delete accounts you no longer use. 

Start with accounts holding sensitive information: banks, tax services, or file storage.

Continue with accounts you use daily: social media, online shopping, or entertainment.

Update the rest of your accounts over time. Create a separate folder(new window) in your Proton Mail account where you automatically forward(new window) emails from your Yahoo account. This will help you quickly spot which contacts are still using your old email address. To remind your contacts about your new email address, set up an auto-reply on Yahoo(new window) each time your contacts email you at your old address.

Once you have updated the accounts you want to continue receiving emails from, you can delete your Yahoo account(new window). This brings you back in control over which websites or organizations have your contact details. 

If later you decide to regain access to any account still associated with your Yahoo address, you can use the recovery email address or the phone number you provided at signup. Alternatively, you can contact the support team of the service you’re trying to gain access to.

Sign up with your Proton Mail address from now on. All of your information and account updates will be securely encrypted.

Use multiple email aliases 

Proton Mail also allows you to receive emails to an unlimited number of aliases(new window). If you don’t want to enter your actual email address, build an alias by adding a + to your username. This feature is available to all users. For example, if your email is, you will also receive the emails sent to in your inbox. 

Aliases together with filters help you manage your inbox. You can also use them to protect against phishing attempts or spam by assigning an alias to each account you register with. This helps you quickly identify the source of spam. 

Organize your new inbox
