Text messaging has always been one of the most effective ways to reach people. But for too long, it’s been stuck in the past—clunky, limited, and lacking the sophistication marketers need to create campaigns that truly perform.
Relay changes that.
Created by Wonder Cave and Rebrandly, Relay is built for marketers who want to go beyond clicks and opens—who want to understand their audience, optimize every message, and scale with confidence.
If you’re using text messaging today, you know how powerful it can be. But it could be more. Relay turns every message into a smarter, more effective connection:
Make your calls-to-action unmistakably yours, driving trust and better engagement.
Tailor every message to feel personal, no matter how many people you’re reaching.
Know exactly what works—who’s clicking, when, and why—so you can optimize and grow.
...and it’s all built on enterprise-grade infrastructure, so it works seamlessly at any scale.
