I've been using it as my main normie email (email is normie tech in general tbh), sure it's less retarded and intrusive than google's shit and has some cool features even in free tier but it's premise of privacy is confirmed psyop. As for whether people think it's sketchy - most niggas can't even recognize that domain in the first place and those who can will think of you as some techbro fag rather than schizophrenic political extremist and a threat to society.
