Marketing and sales run on research, lists, drafts and follow-ups. That groundwork is where AI agents shine, taking on prospect research, content drafts, campaign analysis and outreach preparation.
This guide gathers real examples from people who used agents for growth work. You will see lead research, SEO tasks, social posts, competitor tracking and CRM clean-up, each linked to its source.
The people who get value from this keep humans on the relationship side. Agents prepare the research and drafts; people decide what to send and to whom. That keeps outreach personal and avoids spammy mistakes.
Pick a case below that fits your pipeline, open its page and adapt the prompt. Review every message before it goes out. The most interesting cases are listed first.
What is in this guide: 60 sourced cases, added between 2026-10-15 and 2026-10-15. The tools that come up most often are Custom agent (11), Claude Code (10), Grok Bot (7), and the cases mostly sit under Sales & Marketing (60). They were reported on Reddit (24), X (20), Blog (12). If you only have a few minutes, start with the top three: “Summarize service calls and find local customers”; “Scrape real estate agent leads and start roofing outreach”; “Run outbound sales from research to booked demos”.
Each case page gives a short summary in our own words, a note on why it matters, a reusable prompt broken into steps you can follow, and a link to the original first-hand account. Nothing here is a paid placement, and we only list cases with a working public source.
