A new subscriber joins a list and, before anything else in the workflow runs, the address behind that signup gets checked for typos, dead domains and spam traps. Validate Email is what Cleansify contributes at that point, confirming an email is genuine the moment it lands so nothing downstream wastes an SMS credit chasing an address that was never going to answer.

This works best sitting between a signup trigger and the SMS itself. An Eventbrite registration, a Typeform entry or a Calendly booking all produce an email address worth checking before the workflow moves on, and Cleansify runs that check in the middle of the Zap rather than at the end. Once the address passes, the same Zap can hand off to Mobile Message to send the actual text, whether that is a welcome message, a booking reminder or a simple confirmation that someone made it onto a list.

Cleansify itself never sends a message and never talks to Mobile Message directly, its one action just decides whether an address is worth acting on. Built this way through Zapier, the pairing means the SMS side of a workflow only fires for people who gave a real email in the first place, rather than a text going out to someone pulled from a messy form.
