Most prospect lists are built from who a company is: its size, its industry, its location. Those are static. They tell you nothing about whether now is a good time to email.
A job posting is different. It is a company announcing, in public, what it wants to spend money on this month.
Why this signal works
Think about what a company hiring an SDR is saying:
- Outbound is a priority right now
- They do not already have the person
- Someone new will take weeks to get productive
That gap is the opening. If your offer is getting meetings, "before your new hire ramps" is a real reason for them to talk to you, not a line you made up.
How I built it
I built this as a Clay workflow and ran it on a small sample list. The steps were:
- Find jobs. Search for SDR, BDR and GTM engineer roles posted in the United States in the last 30 days. That matched well over a thousand openings.
- Check the company. An AI column read each job and its company and answered three things: is this a B2B software company, what does the hire signal, and what angle would help them.
- Find the right person. Pull the sales leader, a head of sales, VP, director or founder, at that company.
- Write the opener. A second AI column wrote two short sentences using the role and the angle.
The step that saves you
The job search returns anything that matches the title, including a flooring store hiring a "business development rep". The qualification column catches that. In my sample, companies that were not B2B software were skipped and got no opener at all.
That is the difference between a signal list and a spam list. A cheap check, at a tenth of a credit a row, keeps you from emailing people the signal does not apply to.
Who to write to
Not the recruiter. Not the person who gets hired. The sales leader the role reports to. They own the pipeline problem the hire is supposed to solve, and they are the one who can say yes to help.
At a small company that is often the founder.
What the opener should look like
Two sentences, plain, specific. For example, for a facilities software company hiring a BDR, the opener my table wrote read like this (the first name is left off here):
Saw HubStar is hiring for a Business Development Representative (BDR) this week. Focused lists, messaging, and sequences for workplace and facilities leaders could get meetings and pipeline moving before the new hire ramps.
Notice what it does not do. It does not say "I noticed" or "congrats". It states the signal and connects it to one useful thing.
I did have to fix one thing along the way: the first version printed the raw posting timestamp into the email. A rule in the prompt telling the AI to say "this week" instead of printing a date fixed it. Always read real outputs before you send anything.
What to be careful about
- Do not overclaim. "Before your hire ramps" is fine. Promising a number of meetings is not.
- Do not email on a stale signal. A posting from two months ago may already be filled. Filter to the last few weeks.
- Check the signal means what you think. A BDR role at a staffing firm is a different situation from one at a software company.
- Keep volume small. A signal list is only worth doing if it is relevant, so send to fewer, better-matched people.
When this does not work
If the company already has a strong outbound team, a new SDR is just replacing someone. If your offer does not help someone ramp faster, the timing argument does not apply. Be honest with yourself about whether the signal fits your offer.
