Does anyone have any experience with deal machine? I have seen other land investors on Youtube saying they use them for data aggregation. Trying to decide if I want to pull the trigger or not

For those of you who have built their systems around SMS. What are some mistakes that you wish you avoided or knew about before starting? Roadblocks that might've cost you money or even a potential deal? I finally have Stride and my texting platform set up. Just waiting the 10DLC approval and A2P to be finalized. I'm looking to hit the ground running and will probably start my texting volume you a bit lower to get the hang of it before ramping things up. I'd like to get a head of as many potential mistakes as possible.
