Under the microscope: Eve Sleep Case Study
Eve Sleep + Code Chemistry
In a bid to boost customer engagement and drive email performance, leading sleep wellness brand Eve Sleep partnered with Code Chemistry to enhance their email marketing strategy. By leveraging Code Chemistry’s innovative Email Elements, Eve Sleep integrated dynamic features into their campaigns – click counters, personalised images, and scratch offs. The result? Content that really resonated!
Click Counters
Over Black Friday, Eve Sleep used Click Counters to introduce real-time social proof and build brand trust. A subtle yellow banner in the email displayed a live-updating message – “Join 202 others shopping right now” reflecting the actual number of subscribers clicking through to shop.
This simple, dynamic element tapped into the psychology of herd behaviour, reassuring recipients that others were already taking action and subtly encouraging them to do the same, ultimately driving higher engagement and conversions.
Personalised Images
To add a personal touch to their payday campaign, Eve Sleep used a personalised image that featured the recipient’s first name prominently in the hero section of the email.
Positioned just below the promotional offer, the personalised element was designed to immediately capture attention and encourage recipients to redeem the offer.
The result? Significantly more orders.
Scratch Off
Eve Sleep brought an extra layer of excitement to their payday campaign by using Code Chemistry’s interactive Scratch Off feature. The email creative was bold and eye-catching, with a clear call to action: “Scratch me to reveal your payday offer.” When recipients clicked through, they were taken to a branded landing page where they could digitally scratch off a panel to uncover that month’s exclusive offer.
Once revealed, a celebratory burst of confetti appeared, and the page dynamically updated to show details on how to redeem the offer. This gamified experience not only boosted engagement but also delivered impressive results compared to a control group without the Scratch Off.
