If you don’t want anyone to read your emails the best method is just to encrypt the main text with PGP keys, note you cant really encrypt the email’s metadata though . If you’re looking for a good email experience I would 100% recommend buying a custom domain I love mine.

Not really i don’t use any services that need it.

Anything you pay for will only be as anonymous as the payment method you use, things like bitcoin are not really anonymous since buying bitcoin without know your customer regulations is hard. If your adversary has the resources or your threat model is high enough even paying by mailing cash proposes a risk which is why things like tor need to be free. My advice is get a password manager and create unique long passwords and never reuse usernames to prevent doxxing threats, I use keepassXc for everything even my bank.

I block cloudflareinsights.com which my lemmy instance seems to be using lol.

I dont feel like it does anything new everything it brags about is just standard, anti fingerprinting is kinda cool but if i needed that id just use tor mullvad. The last cool browser is saw was zen

Make your main browser secure and private and use tor/mullvad for anonymity.

I found some of those download youtube sites do work lol. This one works for me i just tested it https://ytdown.to/en2/

I mostly use my custom domain on protonmail for reasons like this.
