Challenge

epres™ needed a way to effectively engage two distinct audiences, professional stylists and consumers, without doubling their lifecycle marketing efforts. Their previous agency struggled to capture the brand’s voice and created delays that stunted their email program’s growth.

Additionally, epres™ aimed to:

  • Increase subscriber growth through onsite pop-ups
  • Improve email segmentation and personalization
  • Reduce unsubscribes and optimize send cadence for long-term engagement
  • Boost revenue and engagement through strategic testing
  • Integrate SMS as a key retention and conversion channel

Solution

Personalized Content with Klaviyo’s Dynamic Blocks

Using Klaviyo’s show/hide blocks, Retencity delivered highly personalized emails to different audience segments within individual campaigns:

  • Existing customers → Encouraged subscriptions with free shipping
  • Non-customers → Promoted trial offers to encourage first-time purchases
  • Professionals → Highlighted product benefits for salon use

This dynamic approach maximized email scope efficiency while increasing engagement, personalization and conversions.Additionally, SMS played a key role in reinforcing these touchpoints, with personalized message sequences driving urgency and repeat engagement.
