    How Kabloom has driven 30% or more of ESCRS registrations for five years

    The European Society of Cataract and Refractive Surgeons (ESCRS) congress brings together ophthalmologists, eye surgeons, researchers and industry professionals from Europe and around the world. The goal was to grow registrations and abstracts, ending with live digital activity at the congress to engage attendees.

    What we did

    Kabloom ran multi-channel digital advertising and messaging, 24 emails across the event lifecycle, social media posting and boosting, and onsite engagement. Persona-targeted ads drove quality traffic during the abstract and registration phases, segmented emails reached exceptionally high open rates, and live social coverage reached 1.2 million people during the congress. Onsite, we supported the event with daily emails, push notifications and sponsor activation.

    The results

    Digital marketing contributed 30% of total registrations and 40% of abstract submissions, and has delivered 30% or more of registrations across five consecutive ESCRS congresses. Emails averaged a 40% open rate, and digital marketing brought 45% of website traffic.

    Why it worked

    Consistency. Five editions of the same team and the same data have turned a good campaign into a reliable one.
