If you're looking to kick Google or Microsoft to the curb and claw back control of your email, this is in my opinion the best and easiest way to do it.
The practically plug-and-play email server makes it not only possible, but relatively easy, to take back control of your email.
Helm will never share your emails with anyone or scan them [...] By design, the Helm company simply doesn't have access to your email.
