We can create backups using Google Takeout, but for the safest and most secure, I recommend using the MailDaddy Gmail backup tool. This automated tool helps you create backups in various formats like PST, MSG, EML, MBOX, and more, and has a zero data loss policy, where every single email will be successfully backed up.
There are other options also available to create a safe email bakcup, like Google Takeout itself. It is safe, but the issue is that it can only save in the MBOX format.
If you are looking for a third-party option to bakcup Gmail Emails, you can also go or emails from any other email clients. You can go for the RecoveryTools Email Backup Tool.
It gives you full control over your emails, lets you save them in any format you prefer, helps you move them to any service easily, and keeps automatic backups so your data always stays safe.
Yet there are other options to choose from, like BitRecover Gmail Backup Tool, Email Backup Wizard, and also the admin center is there which is the official tool by Google to backup Google Workspace emails.
You can use Google Takeout feature to download emails from Gmail to PC safely. The same can be done preciesly with Advik Gmail backup Tool. This software not only backup your email, but also allow you to save them into 30+ file formats. This makes it one of the safest gmail backup solution.
