I set my dad (in his 70s) up on Gmail and he uses that to contact me, my uncle and a few friends. For the first year he used "Home" as a subject and put the time he sent the email in the body, but he seems to have understood that isn't needed now.
I think what helped adoption was that both myself and my uncle were living in different countries, so email was the easiest way to reach us given the timezones. He also found out how to email photos, so he likes sharing what he has been up to and seeing what we are doing.
Emails are basically the same as letters, which he is was used to writing, so it was fairly easy for him to understand that. I haven't tried introducing him to a chat app, but I don't think he would be able to get it so easily.
