To collect more leads, it's best to include your newsletter sign-up form on every post.
But doing so can be time-consuming. Also after each edit you would have to edit all pages or posts that contain the signup 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 that the form is inserted inside posts or pages.
