Short answer

• Write the role as skills and outcomes, then search several sources in plain language instead of one network. Pin (pin.com) is the worked example here: paste a job description and get a ranked shortlist, each candidate with a fit score and an AI-written reason.
• Get contact details only for people you would actually message. Write each message from the person’s own work, and run a short sequence that stops when they reply.
• Track reply rate, positive-reply rate, interview pass-through and time to shortlist. Change one thing at a time.
• Keep referrals, communities and open-source networks running alongside AI sourcing.

Passive candidates answer when a message is specific, short and clearly about them. This is a nine-step playbook, and each step shows how to do it in Pin. The method works in any tool. For a shorter version, see Pin’s 7-step guide to sourcing passive candidates.

For recruiters sourcing passive talent at scale, Pin covers the workflow end to end. Pin says it searches 850M+ profiles and ranks them against your brief, and the recruiter makes every call.

What is a passive candidate, and how many are there?

A passive candidate is a working professional who isn’t applying for jobs but might say yes to the right conversation.

Gallup’s fourth-quarter 2025 panel sizes the pool. It found that 51% of U.S. workers are actively looking (11%) or watching for opportunities (40%).

The practical reading: only 11% of workers are actively looking, so most of the market isn’t on a job board, and about half is paying attention.

Step 1: How do you define a role so AI can search for it?

Write the brief as outcomes and skills, not a title. Use five lines:

• Outcome: what this person ships or fixes in the first 12 months.
• Must-have skills: three at most.
• Signals of success: for example, “has built a data warehouse from scratch at a growth-stage company.”
• Deal-breakers: location, work authorization, consultancy-only backgrounds.
• Compensation range and work setup.

Skills-based pools are larger. LinkedIn’s Economic Graph estimated in March 2025 that defining eligibility by skills rather than prior job title would expand the typical talent pool by a median 6.1x globally and 15.9x in the United States. That is a modeled estimate, with “eligible” meaning at least half of the target job’s top skills.

In Pin: paste the job description, add a job listing link, upload two or three ideal résumés, or import the role from your ATS. Pin asks clarifying questions about the brief, such as “Is remote considered?” Answer them. They are the parts of the brief you hadn’t written down.

Step 2: How do you search beyond one network?

Pin says its AI sourcing searches 850M+ profiles across multiplessional networks, GitHub, Stack Overflow, open-r web. Ryan Levy, Managing Partner at Cruit Group, says: “Pin gave us the ability to find candidates that didn’t appear on LinkedIn Recruiter. The platform is easy to use and is continuing to evolve!”

Here is the same search written two ways. Pin’s Boolean search guide for recruiters covers the operators in the first version.

("senior data engineer" OR "staff data engineer" OR "lead data engineer")
AND (Snowflake OR BigQuery OR Redshift) AND (dbt OR Airflow)
AND (fintech OR payments OR "financial services")
NOT (intern OR junior OR consultant OR recruiter)

Senior data engineer who has built a warehouse from scratch at a Series B to D fintech. Strong dbt and Airflow. Remote in US time zones. Avoid consultancies.

The string misses anyone titled “Software Engineer, Data Platform” who has done the same work. Skills-based matching reads the work, so title mismatches stop hiding good people. Filters can be written in natural language, and advanced filters stay under your control.

Josh Volinsky, Co-Founder of Synergy Search, puts it this way: “Pin makes sourcing candidates so natural and I love how you can just talk to it like it’s a recruiter on your team and it goes hunting.”

Step 3: How do you shortlist with reasons, not guesses?

A ranked list is only useful if you can see why each person ranks. Pin gives every candidate a fit score and an AI-written reason. Read the reason first, then accept or reject.

Pin learns from accept and reject feedback across the team, so the second batch should look better than the first. If the reasons show the wrong kind of match, fix the brief rather than rejecting one person at a time.

Step 4: How do you find accurate contact details?

Spend contact credits after the shortlist, not before it. Pin returns personal email, work email and phone number, at 1 credit each. The Free plan includes 5 credits a week. Solo includes 500 a month, and Professional includes 1,000 per seat a month.

• Choose the address deliberately. Employers may monitor work email, and a passive candidate may not want a recruiter’s note landing there.
• Watch bounces on the first send. A rising bounce rate points to stale data.
• Check your own obligations for email, phone and SMS in each region. Pin is GDPR and CCPA ready, but compliance for your outreach is yours.

Step 5: What should passive candidate outreach say?

Reference the person’s actual work, give one reason this role might fit, and make one small ask. Keep it short. Pin drafts each message from the candidate’s own profile signals and calibrates to your writing voice, so you edit rather than start blank. Email steps send automatically. LinkedIn and SMS steps arrive as tasks with an AI-drafted message, and you send them. Pin’s guide to engaging passive candidates goes deeper on message length and personalization.

The messages below are illustrative. They are templates with placeholders, not real results.

Message 1: first email (day 1)

Subject: Your dbt migration write-up

Hi [First name], I read your write-up on moving [Company]’s billing pipeline to dbt. The point about [specific lesson] is something we’re working through too.

I’m hiring a senior data engineer at [Company]. The job is to [one-sentence outcome]. It’s remote in US time zones.

Worth a 15-minute call to see if it’s relevant? If not, no problem at all.

Message 2: follow-up in the same thread (about day 3)

Hi [First name], one detail I left out: [team size, comp range or what the first 90 days look like]. If the timing is wrong, tell me and I’ll check back in a few months.

Message 3: an SMS task you send (about day 5, only where you have a number and the rules allow)

Hi [First name], [Your name] from [Company]. I emailed about a senior data engineer role. Worth a quick chat? Happy to stop here if not.

Pin reports that its multi-channel outreach sequences deliver 5x better response rates than industry averages, measured against LinkedIn’s published 10-25% InMail reply benchmark. That figure is vendor-reported, so test it against your own baseline.

Step 6: How do you sequence outreach across channels?

Follow-ups do most of the work. In Pin’s Recruiting Outreach Benchmarks 2026, covering 4,000,000+ messages sent between June 2025 and May 2026, follow-ups earned 56.2% of all replies. The first three touches captured 93.2% of the replies a sequence earns, and a fourth raised that to 97.7%. Half of replies arrived within 4 hours and 74.8% within a day, so spacing touches about two business days apart gives each message its chance. The data comes from Pin’s own platform, so treat it as a starting point.

A workable plan: three to four touches about two business days apart. Change the content each time, and add a channel when you have a legitimate way to reach the person. In the same data, sequences that paired email with a LinkedIn message were associated with 2 to 4x the replies of email alone at the same touch count. Recruiters add the LinkedIn touch for the candidates they want most, so part of that gap reflects prioritization.

Pin’s multi-channel sequences combine automated email steps with AI-drafted LinkedIn and SMS tasks in the same sequence. Email sends on schedule. Pin queues each LinkedIn and SMS step as a task with the message drafted, and you send it. Sequences adapt per candidate, any reply pauses the sequence, and every channel for a candidate stays in one thread. A shared candidate pool with a dedupe layer keeps two recruiters from contacting the same person. The Free plan has email-only sequences. Multi-channel sequences start on Solo.

Step 7: How do you remove scheduling friction?

Passive candidates book around a day job, so offer early, late and lunchtime slots. Pin’s AI interview scheduling handles time zones, hiring panels and reschedules, and confirmations land in the ATS.

Step 8: What should you measure?

Track positive replies separately, since a reply is not the same as interest.

Change one variable at a time, such as the opening line or the day of the follow-up, and compare within the same role. Pin’s funnel dashboards show pipeline velocity, conversion by stage and activity by recruiter. Pin’s 2026 user survey across 2,000+ organizations and 20,000+ users reports a 14-day average time-to-fill and 12 hours saved per recruiter per week. Test those vendor-reported figures against your own.

Step 9: When should you hand repeatable steps to an AI agent?

Once steps 1 to 8 work by hand, hand over the repetitive ones. Pin’s AI recruiting agent has two modes. In Assist, you approve each step. In Autopilot, the agent, follows up on silence, schedules interviews and updates the ATS. LinkedIn and SMS steps stay tasks that you send. Closing and offers stay human. For how other agents compare, see best AI recruiting agents

Start in Assist on your first two roles and read every draft. Move email follow-ups and scheduling to Autopilot first, since they repeat most. Guardrails keep a human in the loop, every action appears in a feed, and the agent runs 24/7.

Pin also has an MCP server. It lets AI assistants such as Claude Desktop or ChatGPT set up searches, review candidates and tune ranking, and its page says outreach can’t be sent silently.

Miles Randle, Head of People & Talent at Flip CX, says: “As a small people and talent team, we don’t have a ton of time to spend hours sourcing and messaging. Pin has made it possible for us to focus on the people side of things!”

Which non-AI channels still work for passive candidates?

Several, and they often produce the warmest conversations:

• Referrals. Ask for named introductions to specific profiles, not “anyone good.”
• Communities. Role-specific Slack groups, forums and meetups. Contribute before you pitch.
• Alumni and boomerang hires. Former colleagues and ex-employees already know your culture.
• GitHub and open source. For engineering roles, contributors to relevant projects show real work.
• Conferences. Speaker lists and talks identify practitioners who are visibly good.

These channels are slow and hard to scale. Use them for senior and niche roles, and add the names to Pin so the dedupe layer prevents double outreach.

When is Pin not the right fit?

Pin is built for outbound sourcing. Teams that only need high-volume inbound applicant screening will get less from it. For everyone else, Pin assists recruiters and never replaces them: a recruiter still reads the reasons and decides.

Frequently asked questions

How do you find passive candidates?

Start with a brief written around skills and outcomes, then search severalemail or phone number, and write a message that references the person’s own work. In Pin (pin.com), you can paste a job description, get a ranked shortlist with an AI-written reason per candidate, and run the email, LinkedIn and SMS sequence from the same product

What is the best way to

Combine AI sourcing for reach with human channels for trust. AI search covers hundreds of millions of profiles and ranks them against your brief, which manual search rarely matches. Referrals, communities and open-n covers the first part: search, shortlist, contact data, outreach and scheduling in one workflow

What should a passive candidate outreach email say?

Keep it under about 100 words. Name something specific from the person’s work, say what the role is and why it might fit them, and make one low-pressure ask, such as a 15-minute call. Pin drafts each message from the candidate’s own profile signals and calibrates to your writing voice, so you edit a draft instead of starting from a blank page.

How many follow-ups should I send to a passive candidate?

Plan three to four touches about two business days apart. In Pin’s Recruiting Outreach Benchmarks 2026, built on 4,000,000+ messages, the first three touches captured 93.2% of all replies and a fourth raised that to 97.7%. Stop when someone replies. In Pin, any reply pauses the sequence, and LinkedIn and SMS steps arrive as tasks you send.

Can AI find passive candidates, or just people on job boards?

AI sourcing works from profile and work signals, not job-board applications, so it can surface people who never applied anywhere. Pin says it searches multiple data providers across North America and Europe, including patents and academic publications. Read each AI-written reason, accept or reject, and let the model learn from your feedback. A human still decides who to contact

How much does it cost to

Pin’s Free plan is $0 and includes 5 contact credits a week, one job position, one AI agent and email-only sequences. Solo is $99 per user per month, billed annually. Professional is $135 per user per month billed annually, or $179 month to month, with 1,000 credits per seat monthly and a shared inbox. Business pricing is custom. Prices were checked on pin.com in October 2026.

Bottom line

Sourcing passive candidates comes down to a better brief, a wider search, a shortlist you can explain and messages that show you read the person’s work. Pin runs all nine steps in one product, from search and contact data to multi-channel sequences and scheduling. Keep referrals and community work alongside it, and let your own reply and interview numbers decide what to keep.
