You’ve added me to your email list. I ask for a quick update to my email address and you give me a hard time.
Say what!?!
The moral of the story is to provide help to someone that you have inconvenienced. Especially since you went through the trouble to add them without their permission or without them otherwise opting in to receive your emails in the first place.
Keep a clean list by allowing people to opt in and opt out as they wish. If they need help removing themselves, help them.
