Caitlin, what, in your opinion, is the best free email service to use for a personal account? I am using GMail but just don’t truth the company anymore, even though they’re not getting any any ad money off me because of my filtering/blocking.
If “for pay,” what is a good service?
I can use GnuPG, and have no secrets in my mail, but just want to be sure the US govt. cannot get to my stuff.
Free email, I would use Fastmail because it hides your IP in the headers (webmail) combined with GnuPG for encryption.
Paid for mail, I would not trust anyone with my encryption keys I would still use my own GPG keys, the only reason why I would want to use a paid for email service is if they protected the stored emails from noisy third parties and regularly erased the logs, Countermail and Anonymous Speech both look good to me and are outside the US.
If I get it wrong, don’t blame ok?
I’d never blame you… but, again, how we would ever know really? Thank you for all your help!
I actually used to use Fastmail. But I started getting a lot of spam and ditched it. I think I may need to bite the bullet and try them out again.
(I’d never trust my keys with anyone else either.) Or SSL certificates, which I make myself.
I just completed the migration to Fastmail from Gmail. I feel better already!
I forgot to mention, for people who never used them, that Fastmail free account offers very little storage space, but for text only emails is ok, they also close down your free account after 120 days of not logging in.
