Sales teams lose the thread the moment a lead goes quiet, replying to a text on a number nobody is watching while the ad spend that brought them in keeps ticking over unattributed. Main Campaign exists to close that gap, matching the revenue a lead eventually generates back to the campaign that produced it, but the matching only works if the lead record actually reflects that a reply came in or that a message reached them at all.

Connected through Zapier, Main Campaign can turn Mobile Message's Inbound SMS Received trigger into an automatic Update Lead action, noting that the person has replied without anyone opening a text thread to check. The Delivery Status Updated trigger works the same way, confirming a message actually reached the lead rather than sitting unsent, so the record reflects real contact instead of an outreach attempt that never landed.

For a team tracking which ad dollars turn into paying customers, that small update matters. A lead who replied is worth treating differently to one who never received the text, and having Main Campaign's own record reflect that difference means the revenue matching underneath it stays accurate without a rep going back to tidy up the CRM by hand.
