Ideally, if you are able to host your own server on Linode with Plesk, you will have your own email server available within that system.

It does take some learning to manage your own email server, but if you have someone on your web team that is willing to spend a few hours, you can easily learn the skills via YouTube. Be aware that you can't just enable the email functions and set-up accounts in Plesk and expect to have everything work. You need to understand DKIM, SPF, DNS and a few other technologies so that your email server is working properly and not getting black-listed.

If you don't have someone that can learn those skills and has the time to manage the server, we recommend that you use a secure email provider like Tutanota (https://tutanota.com/) or Proton (https://proton.me/). Both of them provide secure email services that will easily work with any computer platform.

SECURITY NOTE: We do NOT recommend using Gmail. The Gmail service is known to be insecure and Google has a history of parsing individual's email accounts and turning over information to government agencies, even when the content doesn't violate any laws. It's best to stay away from all Google (and other 'free' programs).
