Challenges of Manual Method

• Manual migration using Thunderbird or Apple Mail is not reliable for large scale. Importing large MBOX files will consume a lot of time in syncing depending on file size and internet speed.
• Google Workspace follows throttling limits to upload data over server. Large migrations get stuck, slow down or fail mid-way especially when importing thousands of emails.
• During drag and drop emails partial data may not transfer. This can result in data loss, broken hierarchy or incomplete data transfer after migration.
• There is no dashboard or progress tracking in manual methods. Users cannot verify emails which have been migrated successfully and which are pending or failed.
• Manual steps like folder selection, dragging emails or selecting the correct MBOX files increase the chances of mistakes and especially for beginners or professional users.
