Candidate Response Rate
Definition
Candidate response rate is the percentage of candidates contacted by a recruiter who reply, whether by email, InMail, text or phone. It measures how well sourcing outreach works and is usually tracked by channel, message template and recruiter, alongside the share of replies that are positive.
Also called: Outreach response rate, Reply rate, InMail response rate, Sourcing response rate
Formula
Candidate response rate (%) = Candidates who replied ÷ Candidates contacted × 100; Positive response rate (%) = Interested replies ÷ Candidates contacted × 100
- Candidates contacted
- Unique people who received at least one outreach message in the campaign or period (not total messages sent).
- Candidates who replied
- Unique people who answered, including those who said no.
Worked example
A recruiter sources 150 experienced IT support technicians and sends a three-step sequence. 39 reply (26% response rate); 21 of those are interested (14% positive response rate); 12 complete a screen. The recruiter now knows roughly 13 contacts are needed for each screened candidate.
What counts as a good response rate
Response rates depend heavily on channel, role and how warm the contact is. As rough guides, cold email or InMail outreach to passive candidates commonly lands somewhere between 10% and 30%. Text messages to people who recently applied or opted in get far higher rates, often above 50%, while cold texting without consent is risky under the TCPA. Re-engaging past applicants and silver medalists usually beats cold outreach, because they already know you.
Track both total and positive response rates. A message that provokes many "not interested" replies can look good on response rate and still produce few screens.
What drives replies
- Relevance. Messages that mention something specific about the person's experience consistently do better than generic blasts.
- Clarity. Pay range, location or remote status and shift in the first message. Hourly and contact center candidates in particular skip vague messages.
- Length. Short messages that fit on a phone screen.
- Follow-ups. A sequence of two or three messages over a week or so typically adds a significant share of total replies.
- Timing and sender. Messages from a named person with a real title beat a no-reply address.
See candidate outreach for message structure and sequencing.
Common mistakes
- Counting messages instead of people, which deflates the rate when sequences are long.
- Comparing response rates across roles with very different talent markets.
- Over-sending. Pushing up volume while the rate falls usually means you are burning through your talent pool and your sender reputation.
- Ignoring speed of reply on your side. A candidate who answers and waits two days often goes cold.
Using it to plan sourcing
Combine response rate with later conversion rates to plan effort. If 14% respond positively, 55% of those pass a screen and one in four screened candidates is hired, each hire needs about 52 contacts. For ten hires that is 520 unique people, which tells you whether your talent pool is big enough or whether you need new sources.
Frequently asked questions
How do you calculate candidate response rate?
Divide the number of unique candidates who replied by the number of unique candidates contacted, then multiply by 100. Track positive replies separately.
What is a good InMail response rate?
It varies by role and how targeted the message is. Cold InMail to passive candidates often falls somewhere between 10% and 30%; personalized messages to well-matched profiles tend to do better.
What is reply rate in recruiting?
Reply rate is another name for candidate response rate: the share of contacted candidates who answer an outreach message.
How can recruiters improve outreach response rates?
Personalize the first line, state pay and location up front, keep messages short, send two or three follow-ups, and reply quickly when candidates respond.
