A lead fills in your form with a phone number and an email address, and the email turns out to be fake or mistyped. The bounce eats into time your team could spend elsewhere, and by the time anyone notices, the person has stopped waiting to hear back. Checking that address the moment it arrives, before your team relies on it, tells you straight away whether the deliverability score is high enough to trust or whether the phone number is the safer bet for reaching that same person.

Once an address comes back flagged as risky or undeliverable, a text message becomes the practical backup for finishing the handoff, since Mobile Message can send that message the moment your Zap decides email will not get through. Pairing the two through Zapier means the check happens automatically before anyone types out a reply that never lands, and a slow follow up chase gets replaced with the one channel most people actually check straight away.
