Hey guys, I’m trying to set up nifty image with the merge text field like in Clay’s videos. But once I remove merge field and add {{contact.first_name}} it gives me an invalid message and won’t send. Any help is greatly appreciated

I feel like an idiot, I cannot get past the a2p. I got approved from all of the checkmarks. But the brand keeps getting denied. I’ve applied for an llc for my own business, but that could take God knows how long. I could be wrong but I feel like there’s no way everybody who does this business model has to get this a2p approved individually for every single customer onboarded. That’s worth $99 itself lol. But seriously somebody please help me, I have to onboard 5 people today
