If you’re looking for a reliable automatic Gmail backup tool, one of the best options is using a dedicated backup utility like the MailsDaddy Gmail Backup Tool. It lets you securely log in with your Gmail account and automatically download your emails into formats like PST, MBOX, EML, MSG, HTML, and more. You can choose specific folders, apply date filters, and schedule backups as needed. The tool preserves everything—attachments, formatting, metadata, and folder structure—so your backup is an exact copy of your mailbox. Since the export happens locally on your system, your data stays private and accessible anytime without depending on Google servers. It's a simple, safe, and efficient way to keep a continuous and complete backup of your Gmail account.
