I've been there and currently doing that, but here is what I changed, maybe it works for you as well 1-Twillow has words that are Scammy according to them, ask the X leads support for the list, and work around it 2- have it send 1,2 texts per minute (drip), which is something I'm trying out 3- Have ChatGPT remove the Landline contacts before importing This is not a 100% effective way, but it just brings down the chances of the error rate problem
