Marketing teams that collect leads through forms, checkouts and event sign ups are the audience validTo is built for, since every one of those channels lets through a share of mistyped or fake email addresses without anyone noticing until the newsletter bounces. validTo checks each address as it arrives, long before it becomes a bad send.

Run through Zapier, that Verify Email Address step sits in the middle of a longer automation. A new entry in Typeform or a new lead from Facebook Lead Ads can flow into validTo first, then on to Mobile Message once the address checks out, with the business sending a text through Send SMS to confirm the sign up while it is still fresh in the person's mind. The same pattern works for a new attendee registered through Eventbrite, where a verified email adds a layer of confidence to the phone number sitting beside it in the same record.

For a team that runs both email and SMS off the same list, that check is worth doing once, early, rather than cleaning the list every few months. It also means the SMS confirmation goes to someone who filled the form in properly, not a bot or a mistyped address that was never going to open anything.
