Cold email for recruiting agencies. What actually works when selling to hiring managers

I run cold email outreach for a staffing agency that places contract engineers. We target engineering leaders and VPs of Engineering at Series A to C startups. Here is exactly what works after 14 months of testing.

The ICP took us three months to nail down properly. We tried HR Directors first. Terrible reply rates, under 1%. Switched to engineering leaders and replies jumped to 3.8%. Makes sense. HR Directors get flooded with recruiter emails. Engineering leads get far fewer outbound pitches.

Our current sequence:

Email 1 (Day 1): Reference a specific job posting on their careers page. Something like: "Saw you're hiring a senior React engineer." One sentence about why our candidates are different. Ask if they've been getting quality applicants. Under 70 words. No links.

Email 2 (Day 4): Proof email. One specific placement we made at a comparable startup, the role we filled, how fast we filled it, and whether they renewed for additional placements. Numbers only.

Email 3 (Day 9): The angle flip. Instead of pitching our service, ask about their current hiring process. Companies struggling with hiring respond to this far better than to a third pitch.

Email 4 (Day 15): Breakup. 40 words max. Works surprisingly often.

Current numbers: 4.1% reply rate across 15 PuzzleInbox inboxes sending 200 emails per day. We book 20 to 30 intro calls per month. Conversion from intro call to signed engagement is 35%.

Data comes from Apollo filtered by funding round and headcount. We used to check the careers page manually for the job posting opener. Now Clay automates that step and pulls the open role into our sequence template automatically.

The job-posting-as-opener is the single biggest thing that improved our results. It proves you did real homework in 5 seconds of reading, without sounding like every other recruiter pitch.
