Connect Mailchimp and send each submission to your selected audience.
Collect subscriber data through targeted website forms and send it to Mailchimp for email campaigns and automations. Create newsletter forms, lead magnets, discount popups, surveys, and other acquisition flows.
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.
Show several offers in one popup
Place multiple products or offers in one popup. Visitors can explore the slides and subscribe through a single Mailchimp signup form.
Turn discounts into Mailchimp signups
Offer a promo code in a welcome or exit-intent popup, collect the visitor’s contact details, and send them to Mailchimp for follow-up campaigns.
A/B Test popups on autopilot
Automatically test popup designs, messages, offers, and display conditions. Compare conversion rates and identify the version that attracts more subscribers.
Go global with multilingual popups
