Evrima Technologies boosts clinical trial participation with SMS reminders and two-way messaging

Clinical trial recruitment does not end when someone clicks on an email. For Evrima Technologies, one of the biggest challenges is helping potential participants keep moving through the screening and enrolment process instead of dropping off along the way. SMS became one of the tools that helped close that gap. 

Evrima Technologies provides products and services that connect people with upcoming clinical trials, helping researchers reach milestones sooner and helping new therapies get to patients faster. But moving someone from awareness to enrolment involves multiple steps, from campaign outreach and registration through screening and appointments. Email was already part of that journey, but the team wanted a way to follow up with people who missed, ignored or bounced from those messages. 

That led Evrima to Sinch Engage (formerly MessageMedia). The platform integrated with HubSpot and Evrima’s own recruitment software, allowing the team to send and track SMS conversations within existing workflows rather than treating text messaging as a separate channel.

For new trial campaigns, Evrima can send bulk SMS at scale and follow up with automated reminders when candidates do not take action after opening an email. Instead of relying on manual phone calls when time allowed, the team can now use personalised SMS to prompt potential participants to register their interest and continue through the process. 

The results show why that matters. In one study involving 24,000 participants, automated follow-up SMS delivered a 3.5% click-through rate and a 20.7% conversion rate. In another bulk campaign sent to 11,000 people, Evrima achieved a 100% delivery rate, an 8% click-through rate and more than 1,250 clicks.

SMS also plays an important role once candidates move deeper into screening. Evrima’s patient experience team uses two-way messaging to answer questions, provide support and help people troubleshoot issues in real time. For participants who do not check email regularly, texting offers a simpler and more immediate way to stay in touch. 

According to Senior Marketing Manager Lauren Duffy, participants are very comfortable using SMS because it removes the friction of long email chains or waiting on hold. That ease of communication has helped Evrima reduce candidate drop-off, increase the number of qualified trial participants and cut down on follow-up phone calls.

For Evrima, the value of SMS is not just campaign performance in isolation. It is about making the recruitment and screening journey easier to complete. By combining bulk messaging, automated reminders, MMS and two-way conversations, the company has added a more responsive and accessible communication layer to clinical trial recruitment. 

That is helping Evrima move more people from initial interest to active participation — supporting clinical trial goals, improving the patient experience and ultimately helping therapies reach the people who need them faster.
