How to send an email to user with custom action

If I didn’t know in my life that I would end up with an email. I am 60 years old, and I still work for a company. In which everyone knows and respects me because I am like a grandmother to everyone. But when the time came when I had to use email, I put my hands on my head because it was like torture for me. Then “my grandchildren” turned to , and they taught me absolutely everything how to use it, and I even got to talk to friends on Facebook. So you know that the reverse generation is not as powerless as some people think.
