If a service is ever compromised, you would have chosen to consolidate information that would lead you to be more greatly vulnerable than if you had spread over multiple services.

I signed up for an account after reading about it on this site: https://digdeeper.neocities.org/articles/email Using it via Thunderbird on the desktop and K9 mail on the phone, works well and has been reliable so far.

From the website, thought this would be good to call out: "Signal Update Info is not affiliated with Signal and is not an official Signal website."

...because why would you go to all the trouble to pay Mullvad (presumably to keep your sensitive information away from big tech) to then give it to google in the form of an e-mail should you reach out to Mullvad for support? Google would then suck up any and all data that comes via their gmail service.
