banner popup - Case Study: Scarles – Mailchimp Popup Performance

Background
Scarles had been using a Klaviyo popup for email signups, offering a $10 discount to new subscribers. Over the course of a year, the Klaviyo popup generated 140 sign-ups.

Challenge
Scarles wanted a simpler, faster, and more cost-effective way to grow their email list, without the complexity of advanced popup tools.

Solution
In August 2025, Scarles switched to using a Mailchimp popup with the same $10 offer. The popup was set to:

  • Appear on all pages
  • Show only to new visitors
  • Display after 2 seconds

Results

  • In just the first week, the Mailchimp popup captured 65 new email sign-ups.
  • This is nearly half of Klaviyo’s yearly total in a fraction of the time.
  • Over the first month, the popup delivered 253 new subscribers at a 1.41% opt-in rate.

Why it Worked

  • Simplicity: The Mailchimp popup is easier to set up and manage than Klaviyo.
  • Flexibility: Settings for timing, display, and targeting were easy to adjust.
  • Cost-Effective: Mailchimp’s built-in popup provided quick wins without extra software costs.

Conclusion
The Mailchimp popup outperformed Klaviyo’s in both speed and volume of sign-ups—proving that sometimes simpler, streamlined tools deliver better results.
