With things going the way they are, having secure email becomes ever more important! Communication is critical to information exchange, and secure communication is the holy grail of prepping. For true prepping communication, you should study on Ham radio; but before the SHTF, consider this!
Here is my choice:
https://proton.me/mail?
I have no affiliation with this company, and one email as well as one VPN; is free. They are based in Switzerland, so they are under the most stringent security protocols in the World! Included is a 64 bit encryption, so emails are safer from hacking than hillery's.
If you want more services, they offer them for a good price. I have used them for over 2 years, and they have been flawless! I'm considering monthly multiple emails and VPN's.
Gmail is recorded and datamined, Yahoo is also recorded but I'm not sure on the data mining.
Combining this with duckduckgo for web searching, plays hell on the dataminers! Turning off the GPS helps, but remember Every time you open an app, Google records where you are and what you were there for; including the IMEI number of your Specific phone! This database is the one used in the movie 2000 miles, and can be used for criminal prosecution.
So, I have removed all possible apps from my phone, and if I must use one; I open the proton mail VPN, and then tell them I'm overseas! My job is to obfuscate (confuse) my data so thoroughly, so that they are unable to sell my information!!!!
