Evidence

What do you like best about Evidence?I love the user interface, I like the ability they give to their customers to customize almost everything about the look and feel of the popups and alerts, the widgets looks gorgeous! And it is pretty easy, simple and fast to implement in any site :) Review collected by and hosted on G2.com.What do you dislike about Evidence?I just wish the Evidence team could be even more active on the product updates, I mean they still continue rolling new updates to the platform however I don't feel like they're too much involved into this or at least not as quickly as I would personally prefer. Review collected by and hosted on G2.com.

5.0\u2605Ross W.g2

What do you like best about Evidence?What I really like about Evidence.io is how incredibly easy it makes adding engaging popup notifications to any website. Setting up the tracking pixel is straightforward—no coding required—and within minutes you can start running campaigns like displaying live visitor counts, special offers, or announcements. Review collected by and hosted on G2.com.What do you dislike about Evidence?It covers the basics really well, the platform focuses primarily on popups and notifications without broader marketing automation features, so you might still need other tools for email nurture or CRM integration.
