Research backed cold email team
Several small agents each take a batch of leads, research the company and its ads, and write a personal cold email. A stronger model reviews each email and a person approves before anything is sent.
What it does
- Splits the day's leads into batches
- Researches each site and its public ads
- Writes an email tied to a real gap
- Has a reviewer model check every draft
Your approval boundaries
Approval requiredThese actions always wait for your yes:
- Sending any email
- Adding leads to a sequence
You decide what happens next.
More about this workflow
This setup is for founders and small sales teams who want more time for real conversations. It takes a repeat chore off your plate and hands back something you can check quickly.
First, it splits the day's leads into batches. Next, it researches each site and its public ads. Then it writes an email tied to a real gap. Finally, it has a reviewer model check every draft. It works with your CRM, web search and email, each on its own login with limited access.
You get the prep work done and waiting for you. The agent stops and asks for your yes before sending any email and adding leads to a sequence, and says plainly if a step cannot be undone.

Steps
Do these in order. Test on old data before it touches live work.
- 1Connect HubSpot CRM with its own login, not yours. Grant read scopes, plus notes write.
- 2Set up Web search. Keep it to public search results only.
- 3Connect Gmail with its own login, not yours. Grant read-only plus compose (drafts) scopes.
- 4Paste the prompt where your harness takes instructions. See the note under the Copy button.
- 5Do a dry run on old or test data first. Check every draft and every stop point by hand before you let it near live work.
- 6Read its log after the first real run. Only widen access once a week of runs looks clean.
Safeguards and trust score
The score describes this example setup’s access, approval boundaries, ability to undo changes, and scope.
Can draft things that send or spend, so it sits close to risky actions.
Waits for a yes on: sending any email, adding leads to a sequence.
Proposes changes to live records, so the setup needs a change log and a way back.
Runs on its own login across 3 tools. Fewer connections means a smaller blast radius.
How to raise it
- Access: Take away its ability to send, post or spend. Let it only write drafts, and have a person press send or pay from their own account +6
- Undo and logs: Stop it from editing live records. Have it write the change as a proposal you apply, and keep a log of every change with a way to roll it back +3
- Scope: Cut it down from 3 connected tools to the 2 it needs most, each with its own limited login instead of your full account +2
Do all of these to reach 89, up from 78.
