A missing feature of all newsletters is to easily change e-mail address...
”So sad to see you go!”
”I’m not leaving, I’m just changing e-mail address for the subscription.”
”Please provide a reason for leaving.”
”I’m not leaving, it’s still me.”
”We also offer a monthly newsletter that may be more to your liking.”
”Oh, FFS...”
A minute later...
”Thank you for subscribing! We really hope you’ll enjoy our newsletter.”
In an office building somewhere: Manager for the newsletter high-fiving the person next to them. “We got a new subscriber, we must be doing something right!”
