Or, by post.
If you would rather write me an actual letter, I keep a small PO box and check it once a month:
Margot Lin
Apartado 4221
1000-148 Lisboa
Portugal
I will write back, even if it takes me until the end of the next month.
I read every email. I reply to most of them. I will, at minimum, send you a sentence in return — sometimes that is all I can manage in a busy week, and I would rather send a short reply than no reply at all.
