Use relative countdown timers

A popup with a tempting offer and a timer has a 112% higher CR than a regular one. Add urgency to your signup offer with a countdown that starts separately for each visitor. When someone submits the form, Claspo sends their contact data to your selected Mailchimp audience.

Inspire with video popups

Include a product video, tutorial, or campaign announcement in your popup, then invite interested visitors to join your Mailchimp audience.
