Case Study: EDF Renewables achieves 20% more webinar signups and replaces paid ads with Opensense email signature banners

EDF Renewables grows Webinar signups 20%, replaces paid ads with Opensense email signature banners

EDF Renewables, a leading North American renewable energy developer with over 1,100 employees, faced inconsistent, low-quality email signatures across its rapidly growing organization—poor mobile rendering, rogue formatting, manual disclaimer management, and a need for Active Directory–driven accuracy. To solve this the communications team evaluated signature management options and selected Opensense’s Email Signature Management and Marketing Platform.

Opensense deployed a centralized solution (Design Studio + AD and Office 365 integration) that enforced on‑brand signatures, ensured reliable disclaimers, and enabled easy campaign banners without plugins or changes to employee workflows. Within a day the brand issues were resolved; EDF Renewables saw a 20% increase in webinar signups, 30% higher email engagement, reduced external ad spend, and now manages signature campaigns in under 30 minutes per week with Opensense.
