Hi @juanmolina

Thanks again for a great comment! When I read again this sentence I can understand that it is understood in a different way that I wanted show.

Let's say you write a post and at the bottom of the post you write a link like that:
Check out my online course how to get a btc for free

This is actually a real link that sends to a landing page. If they are interested by what's on the landing page, they can then go one step ahead and sign up for the course. With every mail that they recieve they have the possibility to opt-out from the list. So I don't think that it is invasive but I also don't think that memos are invasive and some people don't agree with that ;-)

When I put this link in the signatures of my posts I leave a trail where interested people could learn more from me. So if I put this link on all my posts, I increase my chances to bring people to my list. Each post with this link is a potential entry point to my list and way to increse my followership.

Best regards,
Achim
