I am glad you learned how to use email: it's hard and we all make mistakes.

Lesson 1: I never opted into your email newsletter. Just because you put an opt-out doesn't make it OK to subscribe me. If everyone operated in this way we would all get even more spam. Do you know why all those email services that handle it professionally do double opt-in? Because people hate your spam.
