You can start by creating a email at tuta or proton. It does not have to be 100% overnight

but then you send a mail to $person, and this $person uses gmail, and now your mail is still indexed by google.

The only way to get around this is to use encryption. dont send plain text email.

And if the recipient uses a Chrome extension to handle the decryption... Google still has access to the cleartext. There's no winning.

Tuta is just horrible, often rejecting account creation altogether. AtomicMail.io is a nice free alternative to Proton.

Thanks for your perspective. I've been using tuta since a year now. Nothing to report

Tuta is pathetic because it asked for my real name, ID verification, and real phone number, altogether defeating the point of anonymity. When I refused to provide identification, it disabled and deleted the new registration. This makes it as bad as Discord.

Perhaps you have a grandfathered account, but times have changed for the worse with Tuta alone.
