Is this a joke?
Employ your search engine of choice and enter “best free e-mail providers”. Pick a few and use the one you like best. ;-)
As for GMail, Google has been trying everything to nail their GMail shut. They even invented their own authentication mechanism just to break competing e-mail clients. Most new clients can deal with it again, but Google will simply keep blocking your client randomly, bombarding you with “Suspicious sign in prevented” messages.
The way Google is “fighting” unfair has been reminding me a lot of Microsoft recently.
