A customer fills in a form, and within moments gets a welcome text that actually reaches them, because the email address behind that signup was checked before anything else happened. That is the effect Email Hippo's Validate email address action has when it sits ahead of Mobile Message in a Zap, catching typos and fake addresses before they turn into wasted contact records or unanswered messages.

Connected to Mobile Message through Zapier, Email Hippo becomes the middle step in a larger automation rather than the whole thing. A lead comes in from Facebook Lead Ads or a Google Form, Email Hippo checks whether the email is genuine, and only then does Mobile Message create the contact, add them to a list or send the first text. The same pattern suits Eventbrite signups, where a bad email is a good sign the phone number attached to it deserves a second look too.

For the business running the Zap, this means SMS contacts start clean. Instead of texting or storing every entry a form collects, only the checked ones make it through, so lists stay accurate and messages land with people who actually filled in the form.
