It never auto-sends.\n\n### Why Twain\nThe research is what makes outreach land and what doesn't scale \u2014 10+ hours of profile-reading for a week of leads, so it gets skipped and the copy gets generic. Twain's campaign **Agent** reads each person and their company and writes the message on a real angle, from a brief you set once in plain language. Same research and personalization a good rep would do by hand, in seconds, at list scale.\n\n### What it does\n\u2022 Normalizes the signal, dedupes, and (optionally) resolves a LinkedIn URL from the email\n\u2022 Calls Twain to research the lead and draft the LinkedIn intro + follow-ups\n\u2022 Posts the draft to Slack for a human to send \u2014 optionally stages it in a HeyReach campaign\n\n### How to set up\n1. Twain account + a LinkedIn intro/follow-up campaign at **https://www.twain.ai** \u2014 its Agent writes the copy.\n2. Paste the `campaign_id` into **LinkedIn Settings**; add the Twain (Header Auth `X-Api-Key`) + Slack credentials.\n3. Point your signal source at the webhook. Generate/Sequence costs 1 credit per lead.\n\nBuilt with Twain \u2014 https://www.twain.ai"
