… got a new subscriber to my newsletter.
In reply to my question, he said that he heard about the newsletter when a friend forwarded it to him.
He then signed up by clicking the “subscribe” button in the newsletter itself.
Most people don’t include a subscribe button in their newsletters. After all, anyone who receives it is already, by definition, a subscriber.
But when they share it, you want to make it as easy and obvious for the recipient to add themselves to the list!
