Justuno ‑ Email & SMS Popups

Lots of options to work with in both design and rules. However, there's one downside: the editor could be a lot more inuitive and optimised, it's pretty difficult to start from scratch so you're almost forced to use a template and there's not too many of those. The app is worth it, but it's not a "1-2-3-done" kinda app.
