for those that want to email a patient secruely look into jumbleme.com once you sign up your email account, you can email anyone yoyu want but changing their email address from x@y.z to x@jumbleme.y.z
you just need to make sure your patients know a password to open the email. For my patients all i do is make the password easy for them to remembmer...which has to do something with their name/id etc.
