A marketing manager running paid campaigns through Microsoft Advertising spends real effort keeping audience lists accurate, adding people worth retargeting and removing people who shouldn't be seeing the ads anymore. Mobile Message can feed that process directly through Zapier, using nothing more than the texts already going back and forth with customers. A reply from a customer can trigger Microsoft Advertising's add contact to customer list action, so that person becomes part of a retargeting audience without anyone exporting a spreadsheet of phone numbers first.

The same reply can just as easily run the remove contact from customer list action instead, taking someone off an audience the moment they get in touch to sort out a question or ask to be left alone. Both actions rely on Microsoft Advertising's own customer list tools, so the lists themselves keep working the way this operator already expects, built from real contact activity rather than a one-off upload.

Because Microsoft Advertising doesn't send its own events back to Mobile Message, everything here starts from the Mobile Message side. Inbound sms received is what feeds the audience updates, and delivery status updated remains available on the account for whenever a different action calls for it. For an advertiser already managing lists inside Microsoft Advertising, the SMS channel becomes another genuine source of audience data rather than a separate, disconnected line of contact.
