I dont really understand why this is not enable by default, it has not sense to offer a discount for the people that arelady took the disctout, and there is no way to block it.

Would be great to be able also based on customer information (or segments) and not only decide in which pages/post, etc. I mean i really need functionality that is totally not usable with mailpoet :(

100% - we had someone come to our office complaining when they click a link (on mobile) from our newsletter, they still get the pop up to join our newsletter every single time - there should be some kind of detection. There also needs to be a delay between each time people see the newsletter popup.
