How HTL-STREFA's Droplet Micron campaign delivered 50%+ conversion rates and validated substantial market demand across Ohio and Pennsylvania.

The challenge

How to establish market presence for the innovative Droplet Micron insulin pen needle in a competitive healthcare landscape while building consumer awareness among diabetes patients across multiple states?
At the outset, HTL-STREFA faced the challenge of introducing a new medical device to consumers who may not have been actively seeking pen needle alternatives. The primary obstacles included educating potential users about product superiority, building market momentum in a crowded diabetes care market, and validating demand across different geographic regions. Additionally, the company needed to determine the most cost-effective approach for customer acquisition – whether direct sample requests or awareness-building campaigns would deliver better long-term value and conversion efficiency.

The solution

Develop a sophisticated multi-market digital advertising strategy across Ohio and Pennsylvania, utilizing three distinct but interconnected campaigns to maximize reach and validate different conversion approaches.

Somnowell Marketing initially launched the Ohio “Take the Micron Challenge” campaign to build direct consumer engagement and awareness. This was followed by a Pennsylvania “Request a Sample” lead generation campaign with a comprehensive 4-step email nurture sequence developed in Klaviyo to maintain prospect engagement.

Finally, we implemented an Ohio remarketing campaign targeting users who had previously engaged with the challenge campaign, presenting them with a lower-commitment sample request approach to capture additional value from existing awareness.

We focused on landing page optimization, multi-platform creative testing across Google Ads and Meta, and continuous performance refinement to maximize conversion rates while maintaining cost efficiency throughout the campaign duration.

“Working with Somnowell Marketing on our Droplet Micron campaigns was transformative for our digital marketing approach. Their strategic multi-market methodology not only delivered exceptional conversion rates but provided us with invaluable insights into customer acquisition efficiency.”
