Marketing teams who run email campaigns alongside SMS live and die by deliverability, and a list full of typos and dead addresses drags down both metrics and reputation. Proofy verifies an email address before it is used anywhere else in a workflow, catching the mistakes and disposable addresses that would otherwise bounce and quietly damage a sender's standing.

For a business collecting both an email address and a mobile number on the same signup form, that verification step can sit in front of everything else. Proofy checks the email first, and only a genuine address moves on to the next step of the Zap, which might add the contact to Mobile Message and send a welcome text. The phone number itself is never touched by Proofy, but the contact record it helps build is more likely to belong to a real person rather than a typo or a throwaway address.

The link between Proofy and Mobile Message runs through Zapier, sitting earlier in the same automation rather than acting on the text message itself. It is a quiet way of keeping a combined email and SMS contact list cleaner, without adding an extra manual check for anyone on the team.
