Most teams source passive candidates reactively: a role opens, a few outreach messages go out, and the effort stops once the pipeline fills or the search stalls. The people best matched to a hard-to-fill role are often employed, reasonably content, and nowhere near a job board, so inbound applications reach only a small part of the market. This guide covers where to find passive candidates, how to earn a reply from them, and what to set up in advance so sourcing builds on itself instead of restarting with each open role.
TLDR:
-
Job boards mainly reach people who are actively searching; passive sourcing is how you reach the rest.
-
Diversify beyond LinkedIn with employer brand content, hashtags, and recruiter social profiles.
-
Referral programs tend to surface well-matched candidates when the rules, incentives, and tracking are set up in advance.
-
Personalized outreach can raise candidate interest, even among people who declined other companies.
-
Some recruitment automation tools can nurture passive candidates with follow-ups and scheduling to reduce dropoff.
What Is Passive Candidate Sourcing?
Passive candidate sourcing is the strategy of proactively targeting and engaging candidates who may be open to new opportunities but are not actively looking for a job. It typically involves identifying passive candidates through their digital footprints (from their LinkedIn profiles to their blogs, publications, and other digital properties) in order to initiate contact and inspire them to apply or interview for an open role.
The Difference Between Active and Passive Candidates
Active candidates are job seekers who are actively looking for a new job and are taking steps to find one, such as submitting applications, networking, and attending job fairs. Passive candidates, on the other hand, are not actively looking for a new job but might be open to considering new opportunities if they arise.
Passive candidates might include people who are satisfied in their current job but are open to hearing about other opportunities, as well as those who are not actively looking for a job but might be open to considering one if the right opportunity comes along. They’re also more likely to be qualified candidates, or at least fit more of your requirements, since you’re seeking them out.
| Dimension | Active candidates | Passive candidates |
|---|---|---|
| Job search status | Applying, networking, and attending job fairs | Working in a role they like, open to the right opportunity |
| Where you reach them | Job boards and inbound applications | Social profiles, referrals, and direct outreach |
| What earns a response | A clear job description and a fast process | Personalized outreach, company culture, and a visible growth path |
| Recruiter effort | Screening inbound volume | Identifying, researching, and nurturing before any application |
| Typical tradeoff | Larger applicant volume with more competition from other employers | Slower to respond, but often a closer fit to your requirements |
How to Find Passive Candidates
Use Social Media to Reach Passive Talent
Gone are the days of advertising on LinkedIn to find candidates. Because LinkedIn can feel oversaturated for passive outreach, it may be beneficial to diversify your social recruiting strategies.
And while most companies are on social, many aren’t using social media recruiting to its full potential. Here are a few ways to get started:
-
Post all jobs to social media. Or, at the very least, post that you’re hiring and consider promoting the post so candidates who come across your profile will know you’re actively recruiting.
-
Use hashtags to target specific audiences, especially for the roles you’re hiring for.
-
Share employer brand content. A 2022 CareerArc and Harris Poll survey found that 58% of jobseekers look up potential employers on social media, so post pictures of your team or testimonials from staff members.
-
Post on behalf of recruiters’ social profiles. Or have recruiters create unique profiles for your company where they can recruit for their open reqs.
Invest in Automation Tools in Your Hiring Process
Automation is the future of passive recruitment, and it’s key to providing an exceptional candidate experience in the passive sourcing process. In a tight talent market, speed is everything.
Since passive talent isn’t actively looking, they won’t be motivated to respond unless you either have incredibly enticing recruiting emails or continuously nurture your relationship with them (similar to a sales prospect). Recruitment automation tools, like Dover, can send timely follow-ups, build talent pools of candidates to reach out to later who responded “not yet”, and automate scheduling so you limit dropoff or losing out to other offers.
Set Up a Referral Program
Referral-based recruiting has long been popular, and for a valid reason: referrals from current employees tend to surface well-matched candidates.
To set up an employee referral program you’ll need to:
-
Create an outline of the rules of your program and document how it works. For example, you should think through: What kind of process do employees go through to make a referral? What kind of incentive is involved? How will you update your website with this added benefit?
-
Next, set up an incentive structure for referring successful new hires, such as bonuses or rewards.
-
Finally, track and monitor the efficacy of the referral program by reviewing metrics such as timing from when the person was referred to when they joined.
How to Engage Passive Candidates
Stress Company Culture and Candidate Growth Potential
According to Deloitte’s 2026 Gen Z and Millennial Survey, younger workers favor stability, skills development, and well-being over fast-paced advancement, with just 25% of Gen Zs and 21% of millennials saying they prefer rapid career progression. This is especially true for passive candidates, who are theoretically happy in their current positions and would need a compelling case beyond salary alone, which makes growth paths and skills development worth leading with.
For passive candidates, outlining your company culture, making sure your employer brand is up to par, and outlining their growth potential are the most important things to convey in your initial outreach.
Send Personalized Sourcing Emails to Prospective Candidates
We’ve all seen the horrifying screenshots of mass recruiting emails gone wrong: the wrong candidate name, or buggy personalization tokens that call out the wrong parts of a candidate’s profile. In a crowded recruiting market, candidates can sniff out what’s authentic from what’s not, which is why personalization matters.
Dover’s free sourcing tools give users the option to generate personalized sentences for candidates using key skills that overlap with your role’s requirements. After analyzing more than 6,000 candidate touchpoints across personalized vs. non-personalized outreach, we found that personalization increased interest in a role by 10-30%. That’s even if the candidate responded as “not interested” to another company’s outreach.
And, even if a candidate isn’t actively looking to make a change, they’re more likely to keep you in mind for future career moves, meaning you’ll see increasing returns over time.
Build Employee Ambassadors and a Strong Brand in Your Industry
Employer branding doesn’t have to be a one-person job: enlist the help of eager team members or those with strong personal brands to promote your content on their personal profiles to see greater ROI. Content shared by employees receives 8x more engagement than content shared by brand channels, which means you can more easily gain visibility over larger, longer-standing brands or competitors.
Though it may feel uncomfortable to ask employees to repost your content, half of working Americans say they’d be willing to share their company’s social media content to their own social channels. 30% of employees say they already have.
An easy way to solve this is to enlist different teams when the content is relevant to them: 24% of employed Americans surveyed say they would be more likely to share company social media if they had a direct connection to the content (for example, an open role in their department).
And if you provide templated language for people to use or edit, more of them may post: 27% of Gen Z and millennial employees in the CareerArc survey say they would be more likely to share company content if the company made it easier.
How Dover Supports Passive Candidate Sourcing
Dover’s free applicant tracking system is built around the sourcing workflow described above. A Chrome extension sends email outreach campaigns directly from LinkedIn profiles, follow-ups can be scheduled in advance, and candidates who reply “not yet” stay in a CRM alongside every active role, so the relationship continues after the first message.
Referrals and scheduling run in the same system. Employees and outside contacts can submit referrals that are tracked through each stage, which gives metrics such as time from referral to hire a single source. The free tier limits the number of referrers, while the $199/month premium plan removes that limit. Candidates can also book interviews through a custom scheduling link, which can cut the back-and-forth that often costs teams a passive candidate who replied only once.
The ATS tracks outreach and follow-ups, but the research and conversations behind them still take hours, and some searches need more of that than a founder or hiring manager can fit into the week. Dover’s marketplace of fractional recruiters adds that capacity, with the average cost per hire at about $4,800 across all roles (costs vary by recruiter, role seniority, and hiring complexity) and verified founder reviews on each profile to assess track record before an engagement starts. Recruiters work inside the same ATS, the layer fractional recruiting agencies are also built on, so sourcing notes, outreach history, and candidate responses stay in your pipeline when an engagement ends.
FAQs
What’s the best way to reach passive candidates who aren’t responding to LinkedIn outreach?
Diversify beyond LinkedIn by combining personalized email outreach, employee referral programs, and social media recruiting across multiple channels. Dover’s internal research across 6,000+ candidate touchpoints found that outreach referencing skills that match the role raised candidate interest, even among candidates who had declined other companies.
How do you write a sourcing email that gets a passive candidate to respond?
Lead with growth potential and company culture instead of compensation, since passive candidates already have jobs and need a compelling reason to engage. Reference particular skills from their background that overlap with your role requirements. Generic templates are easy to spot, and personalization signals that the opportunity was chosen for them, not broadcast to hundreds.
Should I build a referral program or use recruitment automation tools first when sourcing passive candidates?
Both serve different parts of the problem: referral programs tap warm networks and tend to surface higher-fit candidates, while automation tools handle follow-up sequencing and nurture candidates who responded “not yet.” For most early-stage teams, standing up both together makes sense, since referrals fill the pipeline with qualified leads while automation keeps passive candidates warm until they’re ready to move.
Do I need a recruiter if I’m already using an ATS to source passive candidates?
An ATS tracks candidates, schedules follow-ups, and keeps outreach history in one place, but it does not research prospects, write personalized messages, or hold conversations with people who aren’t looking. For a single role or a few hires a year, a founder or hiring manager can often cover that work with an ATS alone. Searches for senior or specialized roles, or stretches when no one on the team has spare hours, can outgrow software. In those cases, a fractional recruiter working inside the same ATS can add sourcing capacity while the pipeline, notes, and responses stay visible to the whole team. Dover’s model pairs a free ATS with on-demand recruiters who carry verified founder reviews, with an average cost per hire of about $4,800 across all roles, though costs vary by role seniority and hiring complexity.
Final Thoughts on Passive Candidate Sourcing and Where to Start
Passive candidate sourcing rarely rewards a single tactic. Teams with a steady social presence, a referral program that pays attention to good introductions, and outreach written for one person at a time tend to build familiarity before a candidate is ready to move, and the right starting point usually depends on hiring volume and the time a team can commit. Some begin with referrals because the setup cost is low, while others start with outreach because a role is urgent. Dover’s free ATS is built with outreach campaigns and referral tracking alongside access to fractional recruiters for searches that need more capacity, though any setup that keeps outreach history and follow-ups in one place serves the same purpose.
