whatsapp is good as well... for email it is all big brothered even if you run your own server...but at least google doesn’t get your eyeballs for their advertising.
Not necessarily so. Encryption simply prevents prying eyes while mail is in transit. WhatsApp and Skype have interesting owners now.
Email is not a reliable protocol like HTML. Look it up, it means something other than what you might think.
You can avoid your helpful host harvesting all your stuff. You do understand the concept of FREE EMAIL, right?
1. Own your own domain.
2. Have a host you can trust and pay for that privilege.
3. Pick your email engine carefully in consultation with your host. This is more important than you think.
Round numbers, my host charges me about $120 per year for unlimited accounts, managing spam, watching for runaways (compromised users), and tech support which I rarely need now. Domain renewals and fees add a little more. You get what you pay for.
Otherwise, may I suggest FAX? It’s point-to-point and as secure as each endpoint is, unless you have someone listening in with a warrant or a snoop in the office.
