To collect more leads, it is best to include your newsletter subscription form on each post.
But doing so can be time-consuming. Also, after each edit you would have to edit all pages or posts containing the sign-up form.
With this addon you can automatically insert your forms at the end or in the middle of your posts and set exclusions for categories or tags or for specific users.
The operation is similar to the addon Popper, with the difference being that the form is inserted within posts or pages.
