The most expensive leak in recruitment is not in your funnel
Everyone in recruitment knows the ritual. New job opening, first step: post an advertisement. Indeed Sponsored, Google Ads, maybe LinkedIn if the budget allows. Logical, right? You need reach, volume, fresh candidates.
But here’s the odd part. The average cost to hire someone is now around $4,700. For managerial positions, it even approaches $35,000. Those figures have more than doubled in ten years. And yet the reflex remains: pump more money into new channels.
Meanwhile, the own database grows every year by hundreds or thousands of profiles. People who once took the time to apply, write a cover letter, come for an interview. And after the rejection, they never hear anything again.
The ice has already been broken
Here lies the crux that everyone misses. With a cold lead from a job board, you still have to earn everything. The attention, the trust, the interest. With someone in your own database, that has already happened. That person once consciously chose to apply to your organization. That’s no small thing.
Research from Indeed shows that 64% of candidates say they want to maintain the relationship, even if they were not hired. Read that again. Two out of three people would like you to keep in touch. And what do most agencies do? Silence.
Greenhouse published last year that 61% of candidates have been ghosted after a job interview. That percentage increases every year. The standard in recruitment is not "we keep in touch". The standard is "we ignore you after the rejection".
And therein lies the opportunity.
The cabinet in the garage
I often think about it this way: you rent your ATS. You rent your job boards. You rent your advertising channels. The only asset that truly belongs to you is the candidates in your own database. With their history, their preferences, their contact moments. That’s the only thing that travels with you if you switch tools tomorrow.
And we treat it like a cabinet in the garage. We know there’s something valuable inside, but it’s easier to go to the store than to search for it.
No mass mailing, no rocket science
I’m not calling anyone to send a bulk email tomorrow to three thousand old candidates. That’s spam, it doesn’t work, it costs you your reputation.
But this: one candidate per day. Targeted. With a specific job opening that matches what they previously showed. That’s an hour of work per week. Personal, relevant, and with context you already have.
The data supports this. Multiple touchpoints over time yield 35 to 50% lower costs per qualified candidate than one-time contact. Companies like Talend fill three-quarters of their vacancies from their own pipeline, including people who were previously just not chosen.
"But our database is outdated"
That’s the most heard counterargument. And it’s partly true. Not everyone in your database is still available. But that doesn’t have to be the case. If 30 to 50% are still open to a conversation, and your email costs you nothing, then it’s mathematically a no-brainer.
The other frequently heard argument is GDPR. But the GDPR allows you to contact existing candidates for similar positions. If someone has explicitly opted out, then no. Otherwise, yes. In 90% of cases, this is simply allowed.
The uncomfortable truth
Recruiters think in "fresh leads" because it’s sexy. Because suppliers sell that. Because a new lead has a clear beginning, a click, an application, a CV. It feels like progress.
Sending an email to someone from three years ago feels like going back. But it’s not. It’s the opposite. It’s the cheapest, warmest, most relevant pipeline you have.
You don’t need to build a system for it. Start with an experiment. Open your database, find ten people who previously applied for a position you currently have open, and send them a personal message. See what happens.
When was the last time you sent a message to someone from your own database?
