How to Migrate Gmail to Fastmail without Losing Emails? Complete Guide
Are you looking for a reliable way to migrate your Gmail account to Fastmail without losing important emails or attachments? Moving an entire mailbox can seem complicated, especially when it contains years of messages, labels, contacts, and calendar information.
Fastmail provides a built-in migration option that can import Gmail mail, contacts, and calendars. However, Gmail labels may be handled differently during the transfer, so reviewing the mailbox structure and checking the imported data afterward is important.
This guide explains the Gmail to Fastmail Migration process in simple steps and covers the important points to check before and after the transfer. It will help you move your mailbox more confidently while reducing the risk of missing messages, duplicate data, or unexpected folder changes.
Method 1: Use Fastmail’s Import Feature
Fastmail provides a built-in option for bringing data from Gmail or Google Workspace into a Fastmail account. This is a convenient choice for users who want to move their mailbox without configuring a separate migration application.
- Sign in to your Fastmail account.
- Open Settings from the Fastmail menu.
- Go to Import and choose Gmail/Google Workspace.
- Select Sign in with Google and log in to the Gmail account you want to transfer.
- Allow the requested permissions and select the information you want to import.
- Choose whether Fastmail should continue checking the Gmail account for new messages.
- Start the import and wait for the process to finish.
This approach is generally suitable for users who want a straightforward migration and do not need extensive control over the transfer.
Method 2: Transfer Gmail Mail Through IMAP
Another option is to use Gmail’s IMAP access to transfer email messages to Fastmail. This method can be useful for users who are comfortable working with server settings and account authentication.
Gmail IMAP Details
- IMAP Server: imap.gmail.com
- Port: 993
- Security: SSL/TLS
- Username: Your complete Gmail address
- Password: Gmail App Password
Enter these details in the appropriate Fastmail import settings, authenticate the Gmail account, select the mailboxes you want to move, and begin the transfer.
Things to Consider with IMAP
Although IMAP provides another way to move Gmail messages, it may require more preparation than Fastmail’s built-in importer.
- Setting up the connection can be technical for less experienced users.
- Transferring a large mailbox may take a significant amount of time.
- Gmail labels and Fastmail folders may not always map exactly as expected.
- Additional authentication steps may be required.
- The process primarily focuses on email and offers less flexibility for handling different types of account data.
Method 3: Use an Automated Gmail Migration Tool
For users managing several Gmail accounts or large mailboxes, an automated solution can make the transfer more manageable. The CubexSoft Gmail Backup Tool is designed to provide options for selecting specific mailbox data and transferring it in a controlled manner.
The tool supports OAuth authentication, which can simplify account authorization while reducing the need to manually configure server details. Users can select the required Gmail data, choose the appropriate migration destination, and follow the on-screen instructions to complete the transfer.
This approach can be particularly useful for administrators, businesses, or users who need greater control over what data is transferred rather than moving an entire account without selection options.
Key Features of the Gmail to Fastmail Migration Tool
The Email Backup Tool makes Gmail to Fastmail migration easier by providing practical options for both individual users and organizations. Some of its useful features include:
- Secure Gmail Access: Connect to your Gmail account securely without having to provide your usual Gmail password.
- Selective Migration: Choose only the labels or folders you want to move instead of transferring the complete mailbox.
- Multiple Account Support: Migrate data from several Gmail accounts, which can be helpful when handling email migration for a team or organization.

- Keeps Email Information Intact: Maintains important details such as the sender, recipient, date, time, message content, and attachments during the transfer.
Frequently Asked Questions About Gmail to Fastmail Migration
Is it safe to migrate Gmail to Fastmail?
Yes, the migration can be completed safely when you use a dependable method and verify the transferred data before making any changes to your Gmail account. It is a good idea to keep the original mailbox available until you have confirmed that important emails, attachments, and other required data are accessible in Fastmail.
Will my Gmail account be deleted after migration?
No. Moving your data to Fastmail does not delete your Gmail account. Your original account remains available unless you decide to close it yourself. Keeping Gmail active for some time after the transfer can also help you confirm that everything you need has been moved successfully.
Can I migrate Gmail to Fastmail without losing emails?
Yes, but you should take a few precautions. Choose a reliable migration method, check the imported mailbox carefully, and keep a backup of important information. Pay particular attention to older messages, attachments, labels, and folders to make sure nothing important was missed.
What happens to my Gmail data after the migration?
Your original Gmail data remains in your Gmail account after the transfer. You can continue using Gmail, keep it as a backup, or remove the data later if you no longer need it. During the transition, you can also use forwarding or an appropriate fetching option to handle new messages.
Can I continue using Gmail while the migration is running?
Yes. You can continue accessing and using Gmail while the transfer is in progress. This can be helpful during a gradual move because you can keep receiving messages while checking the data already transferred to Fastmail.
Which method is best for moving Gmail to Fastmail?
The right option depends on the size of your mailbox and what you need to transfer. Fastmail’s built-in importer is a convenient choice for many individual users. IMAP can work for users who prefer a more manual setup, while an automated migration tool may be more suitable for selective transfers, large mailboxes, or multiple Gmail accounts.
How can I confirm that the migration was successful?
After the transfer, review the imported folders and labels and check both older and recently received messages. Open several emails with attachments to make sure the files are accessible. You should also compare important mailbox sections and review any migration or error reports for items that were skipped or could not be transferred.
Conclusion
In this post, we started by looking at the different ways to move Gmail data to Fastmail. We covered Fastmail’s built-in importer, the IMAP method, and an automated migration tool for users who need more control over the transfer.
The best option depends on your mailbox size, migration requirements, and technical experience.

Keeping your Gmail account intact until the migration has been fully verified can also help avoid accidental data loss.
