The WordPress plugin PopupAlly Pro seamlessly integrates with ActiveCampaign, and you can have an unlimited number of opt-in forms to match your marketing sequences.
PopupAlly Pro is the polite popup solution that does way more than just add popups to your website. With fluid templates that allow you to customize every detail of your opt-in forms, you'll always be on brand and building your list like a champ.
It's not just for popups, either. You can design embedded opt-ins, floating horizontal opt-ins, contact forms, mini-surveys, and split test different options to see what converts best.
