If by privacy proton mail means reducing the overall storage available for the users then they are successful by all means. This strong claim holds up when we see how little storage Proton offers. Looking at the numbers it is quite evident that Proton only has 3% of the storage capacity that Google provides with its free plan. So it’s not surprising that many users wish to forward ProtonMail to Gmail instead.
Even when we move on to paid versions proton still can’t match the sheer amount of storage capacity offered by Google. Moreover, as the world is moving towards more collaborative work staying with a privacy-focused email service might not be the best choice. Therefore, don’t forget to read till the end to know the answer to transfer your emails.

Reasons for ProtonMail Forwarding to Gmail

There are many reasons for the email transfer to Gmail, and we will discuss some of them in the following points:

1. Easy GUI – Gmail’s simple and understandable user interface makes it the perfect choice for email migration from ProtonMail. On the other hand, ProtonMail’s tough learning curve and lack of basic features like email filters make it less interactive for users accustomed to Gmail’s design and benefits.

2. Collaborative Features – Gmail has professional collaboration tools like Sites, Meet, and real-time collaboration on documents and spreadsheets with Google Workspace. Since ProtonMail doesn’t have any productivity suite, users wish to add ProtonMail to Gmail.

3. Massive Account Storage – Gmail has a basic account storage of 15 GB, which is quite large compared with ProtonMail’s 1 GB. Gmail provides account storage expansion options up to 100 GB, 200 GB, and 2 TB for personal accounts, whereas ProtonMail has only 15 and 100 GB upgrades for premium subscriptions. Such a large gap in account storage makes users migrate ProtonMail email to Gmail. Similar reasons exist for adding ProtonMail to Outlook itself.

ProtonMail to Gmail Email Transfer Requirements

The process to forward ProtonMail to Gmail isn’t easy at all. We will explore the requirements for adding emails to Gmail:

ProtonMail Bridge: This is a premium offering provided by Proton Mail developers themselves which allows you to join ProtonMail accounts with external email clients. It works by adjusting the IMAP configuration.

  • It helps in establishing a double-ended junction between your account and the email client using a TLS connection. However, a Single Remote Password is mandatory for this method to work.
  • Only the installation part is manual rest of the work is completed by the bridge itself without any user interference. It does so without hampering the resources (both hardware and software) of the computer.

Access to Both Gmail and Proton Accounts: This goes without saying, that if a user lacks the credentials to any of them no data transfer is possible.

Solutions to Forward ProtonMail to Gmail

After discussing the reasons and requirements to migrate ProtonMail email to Google Mail, we will now explore the solutions for the email migration process in the following sections.

Add ProtonMail to Gmail Manually Using IMAP

You can transfer emails manually using the following steps:

1. Open your ProtonMail account and go to the Settings menu.
2. Select the Forwarding/IMAP section and enable the email forwarding option.
3. Enter your Gmail account credentials and verify them using the Gmail app/website.
4. Configure the Google Mail account to receive emails from your ProtonMail account.
5. Confirm the email forwarding process on both accounts and click the “Save” button to apply the changes.

Note: The ProtonMail Bridge app is available only for Mail Plus and Proton Unlimited users, so you must upgrade your ProtonMail account if you have a free account. Also, you need to activate the Bridge app and configure the IMAP account on it for the manual process to forward ProtonMail to Gmail. A second manual method exists as well. However, it is equally complicated if not more.
