Google will create the archive, which can take hours or even days depending on your data size. You'll receive an email when it's ready to download.
Once downloaded, you'll have an .mbox file. To get these emails into another Gmail account, you'd typically need to use an email client like Mozilla Thunderbird (with an ImportExportTools NG add-on) to import the MBOX file dataset and then sync that client with your new Gmail account via IMAP. This is a more complex multi-step process.
Method 5: Third-Party Migration Tools (Often Paid, But Streamlined)
There are many third-party tools designed for email migration that can simplify the process, especially for large volumes of data or specific requirements (e.g., preserving read/unread status more precisely).
Examples: MailJerry, VaultMe, CloudFuze.
Pros: Often more automated, can handle large migrations, sometimes preserve more metadata (like read status) than POP3 import.
Cons: Most good tools are not free for significant data volumes, and you'll need to grant them access to both your old and new accounts, requiring trust in their security.
Which method should you choose?
For most users who want all existing emails and new emails to go to a new account: Use Method 1 ("Import Mail and Contacts") followed by Method 2 (Automatic Forwarding).
For continuous receipt of new emails only: Use Method 2 (Automatic Forwarding).
For a few specific emails: Use Method 3 (Manual Forwarding).
For a full archive/backup or complex migration to a client: Use Method 4 (Google Takeout), but be prepared for a multi-step process.
For large business migrations or specific needs: Consider Method 5 (Third-Party Tools) if the budget allows.
Always ensure you have a backup of your important emails before starting any major migration process.
