How Monis Grew Their Email List in Klaviyo by 4x with Sleeknote

About Monis is a Danish e-commerce brand specializing in food and supplies for exotic pets. The company helps pet owners across Denmark care for reptiles, amphibians, and small animals with high-quality products and expert guidance. Monis has a team of seven employees, all hired on special terms that fit their individual needs and strengths. Taking social responsibility is an important part of Monis’ DNA. The team believes that no one can do everything, but everyone can do something. They focus on people’s qualities rather than their challenges, a mindset that has been a big part of Monis’ success.

The Results That Started It All

Since implementing Sleeknote in 2020, Monis has seen over 1,500% revenue growth, driven by founder Tommy’s creative use of Sleeknote and Klaviyo to turn visitors into loyal subscribers.

Here’s how he did it.

The Challenge

Monis is a fast-growing Danish e-commerce brand specializing in food and supplies for exotic pets. With thousands of visitors each month, founder Tommy wanted to turn more of that interest into lasting customer relationships.

Instead of simply collecting emails, Tommy wanted a more engaging way to grow his list in Klaviyo and reflect Monis’ playful brand personality.

Email and SMS are key to how Monis sells and communicates: email for storytelling and product inspiration, and SMS for quick reminders and limited offers.

In short, Tommy wanted to make every visitor interaction feel engaging, on-brand, and meaningful while growing a list he could use to drive real results.

Solution #1 Engage Visitors with Spin to Win

To boost conversions and make signup feel more fun, Tommy replaced Monis’ classic signup form, which converted around 2%, with a branded Spin to Win campaign.

Visitors could spin the wheel for rewards like 5% or 10% discounts and free shipping, adding an element of surprise that made signing up more exciting.

Because email and SMS are both key channels, Tommy set up a multistep popup to collect both permissions. The result was impressive: 80–90% of visitors completed the second step, while maintaining a high 8.75% conversion rate overall.

All new subscriber data was automatically synced to Klaviyo, making it easy to trigger personalized follow-ups right away.

Solution #2 Keep Visitors Coming Back with a Christmas Calendar

December is usually a quiet month for Monis, so Tommy wanted to give visitors a reason to return to the website again and again. His idea was a Christmas Calendar popup where customers could open a new door each day.

Behind each door was a unique deal. Some days featured discounts on specific products or categories, and on Christmas Eve, visitors received a special code valid in January to kickstart the new year.

The campaign was a hit. Visitors returned daily to see the next offer, and even emailed Tommy asking when the next door would exactly open.

The calendar encouraged repeat visits and boosted sales as customers explored other products while browsing the daily deals. In fact, December sales outperformed the previous year, and Tommy plans to run the campaign again this year following its success.

The Results

Tommy wanted to grow Monis’ subscriber base and make every signup more valuable, and with Sleeknote + Klaviyo, he exceeded expectations.

  • 4x higher conversion rate from visitor to subscriber after launching the Spin to Win popup (from 2% to 8.75%)
  • 80–90% of the new subscribers completed step two, giving SMS permission in addition to email
  • 13.79% conversion rate from the Christmas Calendar popup, with visitors returning daily to open new offers
  • 1,500%+ revenue growth since implementing Sleeknote in 2020, supported by, among other things, stronger email and SMS performance.

Beyond the impressive numbers, collecting subscribers directly on the website proved far more cost-efficient than paid channels like Facebook, showing why Sleeknote remains a key part of Monis’ marketing setup.
