the thing that got me wasnt that it called, its that it held the conversation. it rang a plumber in melbourne in an australian voice, opened with a proper cold call line, asked for 30 seconds, and when the guy started asking questions it answered every one of them. never broke character, never got confused, and it was steering the whole thing toward booking a meeting. he actually said yeah we can do that. the recording is at the start of this if you want to judge it yourself: https://youtu.be/CnqQ7-iFEXA

spent a while on this and its simpler than i thought. almost nobody personalises cold email because doing it properly takes longer than the email is worth. so everyone merges in a business name and calls it personalised, and every recipient can tell instantly. heres the bit that changed for me. the info you need for a real opening line is already public. a business's google maps listing has their reviews, and reviews tell you what theyre proud of, what theyre struggling with, and half the time the owners name is sitting in the review text. that is enough to write a genuine first line. one i saw opened with "your 218 reviews plus a quick thought" and referenced what recent reviewers actually said. full build if you want it: https://youtu.be/CnqQ7-iFEXA

watched this earlier and the opening is an actual recording of the ai ringing a plumber in melbourne. it books the meeting itself. its three agents. one scrapes businesses off google maps with their reviews and the owners name, one writes an email per lead using those reviews (subject line was literally "your 218 reviews plus a quick thought"), and the third one calls them. he says the whole thing runs for about 30 a month. apify, claude, n8n, supabase, vapi, twilio. https://youtu.be/CnqQ7-iFEXA
