Free guide: pairing a Retell callback agent with real automation (n8n) Built a simple guide + starter n8n workflow for anyone using Retell to handle missed-call callbacks.

Not trying to sell anything in this post, just sharing the free version since I know a lot of us are solving the same "what happens after the call" problem. https://daniellemargret.gumroad.com/l/senotz
