Easy Email Migration Guide Using Thunderbird

3 min. readlast update: 04.15.2026

Migrating emails from an old hosting provider to Gatehills requires careful handling to ensure a smooth transition. Mozilla Thunderbird simplifies this process by allowing users to add both old and new email accounts in one place and easily transfer emails between them. By following these steps, users can move their emails efficiently using its intuitive interface and “copy to” function, making the migration process fast, organized, and reliable without requiring complex setup.

 

Step 1: Create emails in Gatehills

Log in to your Gatehills account, click the Hosting button below your domain, and you will be redirected to cPanel. Navigate to the Email Accounts section and create the same email addresses you were using before (e.g., info@yourdomain.com). Ensure that the email address match exactly to maintain consistency during migration.

 

Step 2: Add both email accounts in Mozilla Thunderbird

Install and open Mozilla Thunderbird. Add both the old and new email accounts using IMAP. IMAP allows real-time synchronization with the mail servers, ensuring that emails remain on the server and can be copied between accounts.

Once configured, both accounts will appear in the left panel of Thunderbird, allowing easy access to their respective folders.

 

Step 3: Copy emails from old account to Gatehills

Open your old email account in Thunderbird and navigate to the Inbox. Select the emails you want to migrate, either individually or by using "Ctrl + A" to select all messages. Right-click and choose “Copy To”, then select the Gatehills inbox as the destination. Repeat this process for Sent, Drafts, and any other folders to ensure a complete migration. Keep Thunderbird open during the entire process to avoid interruptions.

Note: Copying emails before updating MX records ensures that all existing mail history is safely transferred and verified before routing new emails to the new system.

 

Step 4: Update MX records

After confirming that everything has been successfully transferred, you can update the MX records so that new emails start arriving in the correct place, ensuring a smooth and safe transition without data loss.

Log in to your domain hosting CPanel and go to the Zone Editor, click Manage button to view all the records. Add Gatehills mail server records to activate email delivery through Gatehills then remove the old MX records.

 

Step 5: Verify DNS configuration and allow propagation

Ensure that the updated MX records are correctly saved in your domain settings. After making changes, allow time for DNS propagation, which may take anywhere from a few minutes up to hours. Once propagation is complete, all new incoming emails will be delivered directly to your Gatehills mailbox.
