Cold InMail reply rates hover around 10 to 15 percent for most recruiters, even with strong personalization. Warm introductions, where a candidate hears from someone they already know and trust, routinely produce reply rates four to six times higher. That gap has been documented in recruiting research for years. What has been missing is tooling that lets talent teams act on it at scale.
We started pulling together reply rate and time-to-close data from our early-access cohort because we wanted to understand whether the warm-path advantage held up in practice or whether the published benchmarks were optimistic. The short answer: the gap is wider than most of the benchmarks suggest.
What we measured and how we framed it
Our cohort of 47 companies spans a range of industries and hiring volumes, from engineering-heavy teams hiring aggressively to ops-focused companies making a handful of hires per quarter. Across that group, we tracked two metrics: initial reply rate (did the candidate respond to the first outreach?) and days to verbal offer acceptance from first contact.
We are not claiming this is a statistically representative sample of all hiring across industries. These are companies that signed up for early access to Drafted, which means they already believed that warm introductions were worth trying. What the data shows is what happens when a team that is bought into the concept applies it consistently across all open roles.
Reply rates: the gap in the numbers
Cold outreach, defined here as a LinkedIn InMail or cold email to a candidate who has no prior relationship with the recruiter or anyone at the company, produced an average initial reply rate of about 12 percent across our cohort. That aligns with LinkedIn's published data on InMail acceptance rates for sourcing messages. Some teams had better results with highly personalized messages, some had worse. The floor is real.
Warm introductions, where a Drafted-surfaced path led to an employee sending a short intro message to a former colleague or connection, produced an average initial response rate of 61 percent across the same cohort. The best-performing teams saw rates above 70 percent. The floor for warm intro reply rates, even among teams still refining their intro request language, was around 40 percent.
That is not a marginal difference. If a recruiter sends 30 cold messages per week and 4 of them reply, versus sending 15 warm intro requests and 9 of them reply, the entire dynamic of the sourcing workflow changes.
Time-to-close: where the advantage compounds
Reply rate is one thing. What happens after the reply is where the warm-path advantage compounds. Candidates who come in through a warm introduction arrive with more context about the role and the team. The recruiter screen tends to be shorter because the candidate already has a sense of the company from their contact. The hiring manager interview tends to go deeper faster because there is a shared reference point in the room.
Across our cohort, the median time from first contact to verbal offer acceptance was 24 days for candidates sourced through Drafted warm paths, compared to 58 days for candidates sourced through cold outreach at the same companies. That 34-day difference is a full additional month of the role sitting open, with all of its associated costs, and all of the other roles the recruiting team could not prioritize while managing a slow pipeline.
Why the gap is wider than benchmarks suggest
Most published referral research measures the effect of traditional employee referral programs: the employee thinks of someone they know and nominates them. What our data measures is different. It is the effect of a systematic process where candidates are identified against the role criteria first, and the introduction path is surfaced to the employee rather than relying on the employee to think of someone unprompted.
That distinction matters because the bottleneck in traditional referral programs is not employee willingness. It is recall. An engineer knows dozens of strong engineers. When asked to refer someone, they tend to think of the one or two people they worked with most recently, not necessarily the best match for this specific role. Drafted changes the sequence: role criteria first, then network search, then a targeted ask to the right employee with a specific candidate in mind. The employee almost always knows the person and almost always says yes to making the intro.
What this does and does not mean
We are not saying cold outreach has no place in a recruiting strategy. For roles where the company has no relevant network connections at all, cold outreach may be the only starting point. For volume hiring at the entry level, the economics of warm paths are also different.
What the data does say is that for professional roles where the company's collective employee network has any meaningful coverage, defaulting to cold outreach leaves a significant reply-rate and time-to-close advantage on the table. Most talent teams we talk to have not done a systematic audit of how many warm paths actually exist to the candidates on their target lists. When they do, they find coverage in places they did not expect.
A practical note for talent ops
If you are managing recruiting metrics across an engineering or product org, the most actionable thing this data suggests is to run a coverage check before launching a cold sourcing campaign for any new role. Find out which candidates in your target profiles are already connected to someone at your company. If coverage is above 30 percent of the target pool, warm paths are almost certainly worth prioritizing before cold outreach. If coverage is lower, work the warm paths for the candidates where they exist, and use cold outreach to fill the gaps.
The point is to make that a deliberate decision, not a default. Cold sourcing as the default costs time, money, and candidate quality. Starting with warm coverage is a faster way to get to the same pool of candidates, with a much higher probability that they reply.
