When pop-ups are a must

We know that pop-ups are controversial.

We know that many surfers dislike them, though marketers claim a good success rate in getting extra sales, all for the sake of a bit of additional code.

But, even if you oppose pop-ups, what cannot be denied is that if a visitor is going to leave your site without taking any action you may as well provide an exit pop-up.

As someone said "It would be a sin not to use a pop-up"

The content of the pop-up could be a final pitch for your newsletter, or a special bonus or whatever.
