Most cold outreach advice assumes you are selling a product. Recruiting is different: you are selling an opportunity to a person who was not looking for one, and often selling your services to a company at the same time. Two motions, two audiences, one skill. Here is how to run both without sounding like every other recruiter in the inbox.
Recruiters run two kinds of cold outreach that look similar and behave very differently. Candidate sourcing reaches people who are good at their jobs and were not looking to leave, and the currency is a career move worth their attention. Client or business development reaches companies to win the mandate to fill their roles, and that is ordinary B2B sales outreach. Confusing the two, and pitching a candidate the way you would pitch a client, is how recruiter mail earns its reputation. Treat them as separate playbooks.
The passive candidate is the hard, valuable target: happy enough where they are that a generic message bounces off. What gets through is relevance and respect. The structure that works:
Finding the candidate is usually a LinkedIn job, and reaching them well means pairing the platform with email. Our LinkedIn outreach guide covers the connection-and-message side, and this is the exact mirror image of our job-hunting guide, which is worth reading to understand what lands from the candidate's side of the inbox.
Subject: your work on [specific thing], a role worth a look?
Hi [Name],
I came across your work on [specific, real detail] and it lined up closely with a [role] I am helping [Company/type of company] fill, specifically [the genuinely interesting part: scope, team, problem].
Not asking you to apply to anything; just wondered if it is worth a 15-minute call to see whether it is even the kind of move you would consider. Happy to share detail first if useful.
Best,
[You]
Winning the mandate is standard B2B cold email, aimed at the person who owns hiring for the team you can staff, usually a hiring manager or founder. Lead with a specific, relevant proof point (a placement you made in their space, a candidate you already have, a hiring pain you can see), not "we are a recruitment agency". The mechanics are the same as any outbound sequence, and our cold outreach sequence guide covers building it. The recruiter twist is that you often have inventory, a strong candidate, that makes a warm, specific opener trivial: lead with the person, not the pitch.
Recruiting outreach is usually moderate volume and highly personalized, which suits it well: relevance is your entire advantage. Follow up two or three times, adding something each time rather than nudging, and stop cleanly after that. At real volume across many roles, the same fundamentals as any sender apply, authenticate your domain, watch your complaint rate, and warm up if you are sending from a new domain. Grade yours with the warm-up calculator and see how many emails per day is safe.
Candidate outreach handles personal data about real people, which brings it squarely under privacy law. In the EU and UK, recruiters generally rely on legitimate interest under GDPR to contact a relevant professional about a genuinely relevant role, with an easy opt-out; Canada's CASL is stricter and leans toward consent. Because this is sensitive and the rules vary, read our is cold email legal guide and confirm your approach with a professional. Treating candidates' data with care is also simply good recruiting.
Recruiters reach passive candidates, people not actively job hunting, by finding the right person for a role and sending a short, specific message about why this particular opportunity might fit them. Unlike sales outreach, you are not selling a product; you are selling a career move, so the message leads with what is in it for the candidate rather than what you need filled. The best candidate outreach reads like it could only have been written to that person, referencing their actual background, and asks for a low-commitment conversation rather than an application.
Open with something specific to the candidate's experience so it is clear you are not mass-mailing, then explain in a line or two why this role could be a genuine step for them, not just a vacancy you are filling. Be concrete about the opportunity (the team, the scope, the reason it is interesting) and honest about it being an exploratory conversation. Close with a single, easy ask: a brief chat to see if it is worth exploring. Passive candidates respond to relevance and respect for their time, not to job-spec dumps.
Yes, and recruiting is consistently one of the higher-responding categories in cold outreach, because a well-matched career opportunity is genuinely valuable to the right person. Reply rates for recruitment and staffing outreach tend to sit above the cross-industry average, provided the targeting is tight and the message is personal. It works far better than generic "great opportunity" blasts, which are the recruiting equivalent of spam and train good candidates to ignore recruiter mail entirely.
Candidate outreach involves personal data, so in the EU and UK it falls under GDPR, and recruiters typically rely on the legitimate-interest basis to contact a relevant professional about a genuinely relevant opportunity, with an easy opt-out and documented reasoning. Canada's CASL is stricter and generally leans toward requiring consent. Because rules vary and candidate data is sensitive, treat compliance seriously and confirm your approach with a professional. This is general information, not legal advice.
Both, together. LinkedIn is where you identify and research passive candidates and send a first light touch, and email is where a more considered message can land without the noise of a crowded LinkedIn inbox. Sequencing the two, a LinkedIn view and connection followed by a specific email, makes you a real person rather than one more recruiter message, and gives the candidate two low-effort ways to respond.
lemlist sequences email and LinkedIn together, which is exactly how passive-candidate outreach works. Personalize at scale, follow up automatically, and keep both motions in one account. Start a 14 day free trial.
