Guides
Cold outbound is the channel everyone did badly, got burned by, and abandoned — which is exactly why it's open again for founders who do it right. These guides cover the whole discipline: what an AI prospecting agent actually is, how signal-based outbound works, how to source and research buyers without bought lists, what the alternatives really cost, and the mistakes that burn domains.

The five questions to answer before any message exists — fit, right person, situation, asset, and veto — and what AI actually automates versus what stays human.

7 Outbound Automation Mistakes That Burn Your Domain (and Your Brand)
Primary-domain sends, cold mailboxes, Chromium bots, unproven pitches, no human review, opt-out re-engagement, vanity metrics — ranked by blast radius, with fixes.
