Get your own domain name and a low cost hosting package. Most include email service, some, with ‘unlimited’ email accounts.

If you are emailing people on other services, especially like on G-mail, it doesn’t matter how secure your own email host is, your messages are vulnerable.
That’s why all my friends and associates have email accounts on at least one of my own domains, so no one is reading our messages to each other.
