More highly converting optin types

There are cases where you would find popups, sidebar, and in-post optin forms an inappropriate solution. That is why we offer different optin form types such as notification bars and slide-ins popups, so you don’t have to rely on one way of collecting leads and install multiple software and platforms to achieve them.

Powerful Content Locker

Block a portion of your content for subscribers only. Content locking requires users to enter their email addresses to see the full article; otherwise, they will see a blurred content.

Our exit-intent popup technology and slide-ins trigger convert abandoning visitors into subscribers by your optin campaign at the precise moment they are about leaving your website.

If your opt-in form displays too early, your reader might not yet be willing to subscribe, and waiting too long will make you lose out on new leads. Our Pageviews and Time on Site triggers give you fine-grained control over the display of your optin campaigns.

The Scroll Trigger displays optin forms or messages only after a visitor scrolls a down a specific percentage of your page.
