Summary: Gmail users often face situations where they want to backup emails or access emails independently of the web interface. Hence, they decided to migrate Gmail to IMAP to sync their emails between Gmail’s servers and local email clients. This way, the user can read emails and other data without internet access. Moreover, a professional utility, the MacSonik Gmail Backup Tool, enables users to selectively migrate emails without any data loss. Now, let’s begin with the blog.

User-Query: Hi, I need a way to migrate all my Gmail emails to another IMAP server. I want to transfer inbox, sent items, drafts, and custom folders safely, preferably in bulk, without losing any data or creating duplicates. Can you suggest the best method or tools for this on macOS?

Why Do Users Import Gmail Emails to IMAP?

The user usually imports their Gmail emails to an IMAP server to sync their email data in real-time. Given below are the reasons why:

  • Importing emails into an IMAP server, it allows users to access the emails from any email application. This makes email management seamless across platforms.
  • Users import Gmail emails into IMAP so that they can read, reply to, and organize emails when the internet is unavailable.
  • A local backup of emails can be maintained by importing Gmail emails into an IMAP server account.
  • IMAP is ideal while moving from Gmail to a new email provider. It also preserves the folder structure, labels, and attachments.
  • Advanced email management is ensured when the Gmail client is connected with the IMAP server.

Top Ways to Migrate Gmail to IMAP Account

The user can migrate their Gmail emails to an IMAP server using two processes. The first one is a manual process that uses Apple Mail and the Thunderbird email client. The second one is through a professional tool that provides an error-free migration experience.

Method 01: Using Apple Mail

Apple Mail provides full IMAP support, and this way users can manually move Gmail account to IMAP. With this approach, the email content, attachments, and the folder structure remain intact.

The following are the steps to start migrating emails:

  1. In Apple Mail, head to Mail > Add Account > Other Mail Account and hit Continue.
  2. Then, enter the Name and Sign In with your Gmail account credentials.
  3. Apple Mail will automatically detect the IMAP server settings for Gmail, and then click Done.
  4. Similarly, add the target IMAP-enabled email account where you want to migrate emails.
  5. Once both accounts are added, select the emails from the Gmail folder.
  6. Drag and drop these selected emails into an IMAP account folder.

Limitations: If the mailbox is large, then this approach will take a lot of time. The Gmail labels will not be migrated properly.

Method 02: Via Mozilla Thunderbird

Thunderbird is an open-source email client that supports the IMAP protocol. Compared to Apple Mail, it offers more control to users over their email folders, batch transfers, and labels to transfer Gmail to IMAP.

Use the step-by-step process to initiate the migration process:

  1. Launch Mozilla Thunderbird and then go to Email > Set up an Account.
  2. Then, enter your Name and Gmail account credentials. Click Continue.
  3. After that, click on Account Settings > Account Actions > Add Mail Account.
  4. Next, input the name and target IMAP email account credentials.
  5. Now, fill in the server account details and click on Done to finish setting up the account.
  6. Select the Gmail emails to migrate and right-click on them. Choose Copy To > Target IMAP Folder.

Limitations: This method can be a little time-consuming as it involves multiple technical steps. Also, large mailboxes take a considerable amount of time to sync.
