Gmail, Yahoo mail, Hotmail? What email address do you have? Which email provider do you prefer and why?

I am 75 years old and my name is Maria. I am living in Romania and this internet thing is news for me. My children live far away and I was thinking about keeping in touch with them through email and Facebook and video call. This is why I am asking your opinion. Thank you very much for your time!
