Been using Convertful for over a year and it is the best popup marketing software available anywhere. I love the dozens of pre-made templates available to start from as well as several different conversion options that allow you to use popups for a variety of marketing activities.

I've used a number of different solutions for opt-in forms and CTA notifications and so I have experience here. I've used Optin Monster, Thrive Leads, Lead Pages, ConvertPlus and others. The one I like the best is Convertful. Not only do they give you a lot of template options, but there are lot of options for integrations as well as actions taken after buttons are pushed, etc. They are also always looking to improve the product, with steady improvements since launch. This is software targeted for direct and online marketers and the developer has gone to the effort of attending conferences to meet with some of the top direct marketers to get their thoughts on what they would want in the product. Everything has worked very smoothly and they have never had downtime, so there has never been any problems with using them. They even have GDPR options if you are in the EU. Plus, they give you some decent analytics.

Well, the simplicity and feature focused approach is my all time favourites in every softwares. Fortunately Convertful is fullfill my expectations as it's user experience is focused on this values. It was easy to setup and apply into my website. I like that I can check the rendered form on mobile and desktop view so I can be sure there is no issue on both platform. The team is very responsive and from time to time they bring some new feature into the system. The last one was an UTM builder. Even if it is a free function and everyone can use it I really like this kind of useful developments.
