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.
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.
