Looking to add ProtonMail emails to Gmail? This blog will walk you through three ways: forwarding new emails, moving old emails for free, and migrating a full mailbox in bulk.

In order to forward ProtonMail to Gmail, add your Gmail address as a forwarding address in Proton Mail’s settings and then confirm it from the verification email. Forwarding generally needs a paid Proton plan and covers new messages only. In order to move existing emails, export them from Proton & import them into Gmail using Thunderbird or a migration tool.

Which Method Should You Use?

Feature Auto-forwarding Bridge + Thunderbird Dedicated Tool
Moves Old Emails No Yes Yes
Moves New Emails Yes No No
Cost Paid Proton plan Paid Proton plan Software license
Difficulty Easy Medium Easy
Best For Ongoing use Free one time move Large mailboxes

Before You Start

  • You need to have a paid Proton plan for forwarding and Bridge both. Free accounts cannot use them.
  • Forwarded emails reach Gmail as regular messages. Therefore, Proton’s end-to-end encryption no longer protects them there.
  • Check that your Gmail account has sufficient free storage for the mail you are moving.

Method 1: Auto Forward New ProtonMail Emails to Gmail

  1. Login to ProtonMail account and click the gear (setting) icon.
  2. Now, select “Filters and Addresses” from the setting menu.
  3. Go to “Filters” section and click the “+ New Filter” button
  4. Now, configure the filters: “Apply Filter to Messages,” and choose “All Messages” to forward all incoming emails.
  5. Under “Perform the following actions,” select “Forward.”
  6. In the “Forward to” field, enter your Gmail email address.
  7. Select your preference under “Keep a copy in inbox.” or not.
  8. Once you have configured the filters click save to forward ProtonMail to Gmail.

Now, open Gmail and approve the confirmation email from Proton. Then you can send a test message to your Proton address and check that it arrives in Gmail.

Method 2: Move Old Emails without Paid Software (Bridge + Thunderbird)

Gmail cannot connect to Proton directly. So, this method uses Thunderbird as an intermediary.

  1. Install Proton Mail Bridge and sign in with a Proton account.
  2. Add your Proton account to Thunderbird using the IMAP and SMTP details that Bridge shows you.
  3. Add your Gmail account to Thunderbird over IMAP.
  4. Drag your Proton folders into Gmail, or right click a folder and choose “Copy to”.
  5. Finally, wait for the sync to finish. Then spot check a few folders in Gmail.

It is free, but slow for large mailboxes, and also Bridge must stay running the whole time.

Method 3: Bulk Migrate ProtonMail Emails to Gmail

A ProtonMail account allows users to forward emails but does not provide a direct way to migrate data. Hence, the professional software is the preferred and widely used solution to permanently migrate ProtonMail to Gmail account. 4n6 MBOX Converter allows you to export ProtonMail to Gmail easily and quickly.

Forwarding vs Migration: What’s the Difference?

In simple words, forwarding sends new emails to another address. Migration copies the emails that already existed in your mailbox. So, if you desire to leave Proton for good, you will usually need both: migrate first, and then forward.

Why Move from Proton to Gmail?

There is no doubt that ProtonMail is one of the secure email services. However, we cannot ignore the fact that even the paid version of Proton Mail has less competitive features and storage capacity than free Gmail. Hence, sticking with Proton just because it is secured may not be the best option.

  • Storage capacity: ProtonMail has a very limited storage capacity even in the paid version. Gmail offers 15GB of storage for free which can be expanded up to 2 TB, while Proton Mail only offers 500MB with only 100 GB of expansion. The plans at Proton Mail to expand storage space are expensive, starting at $119.88 per year.
  • Access to the Google Environment: Gmail is essentially part of the larger Google ecosystem. If you use other Google services like Google Calendar, Google Drive, Contacts, and more, migrating ProtonMail emails in Gmail can contribute to a more premium experience.
  • Backup Purpose: Forwarding emails to Gmail can be a backup plan. In case you have problems accessing your ProtonMail account, you have copies of important emails in Gmail and can access them at any time.

Troubleshooting Common Problems

Forwarding is not working

You need to confirm that you approved the Gmail verification email, and also check Gmail’s spam folder.

No confirmation email

You need to wait a few minutes, and then re-add the address.

Missing emails or attachments:

You should re-check the export and compare folder counts on both sides.

Duplicates in Gmail

This may usually happen if a folder was copied twice. You can delete the extra copy and run the transfer once.
