Summary: In this article, we explain how to migrate Gmail emails, contacts, and calendars to Proton Mail. You’ll learn how to use Proton Mail’s Easy Switch feature to import your existing data and set up Gmail forwarding so you can continue receiving new messages in Proton Mail. The guide provides a simple way to transition from Gmail while keeping your important mailbox data organized and accessible.

Why Are People Switching from Gmail to Proton Mail?

Privacy has become a major concern for many Gmail users. People are becoming more careful about how their personal information is handled, especially with growing concerns around data security and Google’s advertising ecosystem. This has led many users to look for an email service that puts privacy first.

That’s where Proton Mail comes in. Unlike Gmail, Proton Mail is built around privacy and follows a subscription-based business model. It is also based in Switzerland, where strong privacy laws provide an added level of protection. For users who want more control over their personal emails and data, this can make Proton Mail an appealing alternative.

Businesses are also considering the switch. Companies that handle sensitive customer or business information may find Proton Mail useful for meeting privacy and compliance requirements, including GDPR-related needs. Proton also provides Data Processing Agreement (DPA) documentation for organizations that need it.

The good news is that moving from Gmail doesn’t have to be complicated. Emails, contacts, and calendars can be transferred using Proton Mail’s Easy Switch feature or dedicated migration software. This makes it easier for users and businesses to move to Proton Mail without losing their existing mailbox data.

Native Method to Migrate from Gmail to Proton Mail Using Easy Switch

Proton Mail’s Easy Switch is the simplest built-in option for moving from Gmail to Proton Mail. It allows you to import your existing Gmail emails, contacts, and calendars directly into your Proton Mail account. You can also use it to continue receiving new Gmail messages in Proton Mail, making the transition much smoother.

The best part is that the process doesn’t require any software installation or complicated computer setup. Easy Switch is available through Proton Mail’s web interface and can be used with both free and paid accounts.

With your existing mailbox data transferred and new Gmail messages still accessible, you can gradually move to Proton Mail without worrying about losing important emails or other data.

Steps to Connect and Import Gmail to Proton Mail

Proton Mail makes it fairly simple to bring your Gmail data into a new account using Easy Switch. Follow these steps:

  1. Sign in to your Proton Mail account through the web interface.
  2. Click the Settings gear icon and select All settings.
  3. From the left-side menu, select Import via Easy Switch.
  4. Under Choose your service to connect with, select Google.
  5. Click Continue, sign in to your Gmail account, and allow the required permissions.
  6. Return to Import via Easy Switch in Proton Mail.
  7. Select More import options and choose Google as the service provider.
  8. Select the data you want to move, such as emails, contacts, and calendars.
  9. Start the import and allow Proton Mail to complete the migration.

Things to Consider When Using Easy Switch

Easy Switch is a convenient option for transferring Gmail data, but there are a few limitations worth knowing before you begin:

  • Account connection limit: Free Proton Mail users can connect one Gmail account, while Plus users can connect up to three.
  • Spam and Trash: Messages stored in Gmail’s Spam and Trash folders are not imported.
  • Contacts: The contact import limit is 10,000 contacts.
  • Folders and labels: If your Gmail account contains more than 2,000 folders or labels, or folder names longer than 100 characters, you may need to customize the import and rename some folders.

Alternative Method: Migrate Gmail to Proton Mail Using a Pro Tool

If you need to migrate data from multiple Gmail accounts or want more control over the transfer, a dedicated migration tool can be a useful alternative. The CubexSoft Gmail Backup Tool is designed to export Gmail data, including emails, attachments, contacts, and calendars, while preserving the existing folder structure.

The tool supports Windows and Mac systems and can handle bulk migrations, which can be particularly useful for businesses or users managing multiple accounts. It can also help simplify the migration process when the limitations of Easy Switch make a direct transfer less convenient.

How to Transfer Gmail Emails to ProtonMail Directly Using CubexSoft WebMail Backup Tool

  1. Download and install the CubexSoft Email Backup Tool on your Windows or Mac computer. Launch the application and choose Gmail as the source email service.
  2. Enter the required Gmail account details and allow the necessary access so the software can read your mailbox. Make sure the required Gmail settings are configured before starting the process.
  3. After successful authentication, the software displays the available Gmail folders. You can review the mailbox structure and select the folders you want to move to ProtonMail
  4. Choose the option for transferring the data to another email account or IMAP server and enter the required ProtonMail account details. The destination account should be properly configured to accept the incoming mail data.
  5. Once the source, destination, folders, and filters have been selected, start the migration. The software processes the selected Gmail data and transfers it to the destination account. A progress status lets you monitor the operation.
  6. After the process finishes, sign in to ProtonMail and check the transferred messages. Open a few emails with attachments and verify important folders to make sure the migration has completed as expected.

Why Choose a Gmail to ProtonMail Migration Tool?

Switching from Gmail to ProtonMail can be a smooth process with a reliable migration solution. The tool offers several features that make transferring email data easier, especially for users handling multiple accounts.

  • Migrate Multiple Accounts: Users can transfer data from several Gmail accounts to ProtonMail in one go. The Batch Mode feature allows account details to be added through a CSV file, making large-scale migrations more convenient.
  • Simple and User-Friendly: The interface is designed to be straightforward, so both technical and non-technical users can operate the tool without difficulty. There is also no requirement to install additional third-party applications.
  • Preserve Email Data: Emails can be moved along with their important elements, including attachments, To, From, Cc, Bcc, Subject, dates, formatting, images, and signatures. This helps retain the original email content during migration.
  • Bulk Email Transfer: Users can move a large number of emails to ProtonMail simultaneously rather than transferring them individually. The process is designed to support bulk migration without imposing file-size restrictions.

Overall, the tool provides a practical way to move Gmail data to ProtonMail while keeping the process simple, organized, and accessible for users with different migration requirements.

What to Do After Moving From Gmail to ProtonMail

Once your Gmail messages have been transferred to ProtonMail, do not delete your old Gmail account immediately. Take a few minutes to verify the migration and make sure you have everything you may need in the future.

Start by checking your ProtonMail inbox and folders. Open some important emails, verify attachments, and make sure the messages you rely on most are available. The storage shown in ProtonMail may be different from Gmail because certain folders or messages may not be included during migration.

You should also back up your complete Google account before closing it. Gmail is only one part of your Google account, so use Google Takeout to save copies of important data from services such as Drive, Photos, Contacts, and others.

Next, tell your contacts that you have moved to a new email address. Update the email address on important websites and services, especially banking, workplace accounts, healthcare portals, subscriptions, shopping sites, and other platforms where you receive important notifications. Also check the recovery email and password settings for these accounts.

After everything has been checked, remove any remaining Gmail connections or permissions from ProtonMail and other services. Once you are confident that Gmail is no longer required, you can proceed with closing the old account.

Frequently Asked Questions

Why is my imported ProtonMail data smaller than my Gmail data?

The amount of data shown after migration may not be identical to the storage used by Gmail. Depending on the migration method and settings, folders such as Spam and Trash may be excluded. Selected folders and other migration options can also affect the final mailbox size.

Can I choose which Gmail folders or labels I want to migrate?

Yes. You can generally select the folders or labels that you want to transfer, depending on the migration method you use. With Easy Switch, pay attention to the folder hierarchy because excluding a main folder can also prevent its subfolders from being imported.

Is moving from Gmail to ProtonMail worth it?

It depends on what you expect from your email service. Gmail is a convenient option for users who regularly use Google Drive, Photos, Calendar, and other Google services. ProtonMail is aimed more toward users who want greater privacy and secure communication.

If privacy is a major concern, ProtonMail may be a worthwhile alternative. However, users who depend heavily on Google’s ecosystem may find Gmail more convenient. It is best to compare the available plans and features based on your own requirements.

Is my information protected after moving to ProtonMail?

ProtonMail uses encryption and security measures to protect information stored within its platform. However, the type and level of encryption can depend on how the email is stored, sent, or accessed. If security is your main reason for switching, review ProtonMail’s current encryption and privacy information before completing the migration.

Conclusion

Switching from Gmail to ProtonMail becomes much easier when you plan the final stage carefully. Whether you use ProtonMail’s built-in migration option or a dedicated migration tool, always verify your transferred emails before removing your Gmail account.

Create a backup of your Google data, inform your contacts, update your email address on important services, and remove old Gmail connections. After completing these checks, you can confidently move forward with ProtonMail without leaving important data or account access behind.
