Most candidate replies come after the first email

When a candidate opens your email and does not reply, the most likely meaning is "not yet". Recruiting data shows that an open without a reply is the normal result of a first email, and that most of the replies a sequence will ever earn arrive on a later one. The useful questions are how long to wait, what the next email should change, and when to stop.

An open without a reply is the usual first result

Gem's benchmarks for recruiting email come from nearly 8 million outreach sequences sent through its platform between June 2021 and May 2022. The first email in a sequence saw a 61.4 percent open rate, an 8.3 percent reply rate and a 3.9 percent interested rate. That is more than seven opens for every reply. By the fifth email the cumulative figures reached 78.3 percent opened, 21.3 percent replied and 7.9 percent interested, and sequences longer than five did no better.

Do the subtraction and the pattern is clear. Of the 21.3 points of replies, 13 arrived after the first email, about 61 percent of the total. Half of the interested replies, 4.0 of the 7.9 points, also came after the first email. Gem's explanation is simple: passive candidates are less likely to answer early emails because they already have jobs, and follow-ups reach them at a moment when they can think about the offer.

Newer data says the same. Pin's 2026 recruiting outreach report covers more than 4 million messages sent by over 1,500 recruiting organizations between June 2025 and May 2026. Its reply rate was 5.52 percent on the first email and 5.40 percent on the second, then 4.21, 3.34 and 2.93 percent on the next three. Follow-ups earned 56.2 percent of all replies. Healthcare shows the gap most sharply: candidates opened 51.8 percent of recruiting emails and replied to 2.81 percent, about eighteen opens for every reply. Pin reads that as a group that reads carefully before deciding whether to answer.

How a candidate's silence differs from a buyer's

Sales advice about opened, unanswered email often pictures the message moving around a company, forwarded to a manager or waiting on a budget. A candidate's decision is a different kind of decision. It is personal, it usually cannot be talked over with their current employer, and it competes with a job they already have. That is our reading rather than a measured fact, but it fits Gem's point about employment and the long tail of replies in both datasets.

Silence also means different things at different stages. SHRM's 2025 Talent Trends research found that 41 percent of organizations see candidates ghosting them during the interview process. A candidate who stops answering after an interview has left a conversation they had joined. A candidate who opened one cold email has not joined it yet, and the numbers above say a later email is often what brings them in.

When to write again

Pin's reply timing gives the first half of the answer. When candidates replied, half did so within four hours, 74.8 percent within 24 hours and 93.9 percent within seven days. After two quiet days, that particular email has probably done most of what it will do, and Pin advises that the next touch is due once 48 hours pass in silence.

Gem's data adds the second half. Its sourcers most often left six days between the first and second emails and six more before the third. A one day gap produced the highest open rates, while six day gaps produced the highest interested rates. Pin's 48 hours is inferred from when replies arrive; Gem's six days comes from comparing the outcomes of different gaps. If interested candidates are what you want, the measured comparison is the better guide. Read the first email's silence after two days, and let the second one wait most of a week.

Two quiet days answer the first email. The candidate may still be deciding.

What to change in the next email

• Give it new information. A second email that repeats the first asks the candidate to make the same decision twice. Add the salary range, the team, a specific project, or the reason their background fits.
• Consider a different sender. Gem's 2024 analysis of 4 million recruiting emails found that sending on behalf of a hiring manager or senior leader can improve replies by 50 percent or more, yet only 22 percent of recruiters do it. Gem's 2022 guide suggests the recruiter sends the first email and the hiring manager joins from the second.
• Plan to stop after four. The same 2024 analysis found that a four stage sequence earned twice the replies of a single email and nearly 68 percent higher interested rates, with engagement flattening after the fourth. In Pin's data, three touches captured 93.2 percent of replies and four captured 97.7 percent.
• Watch each person's pattern. A candidate who opens your second email several times over two days is behaving differently from one who opened the first once on the day it arrived. A single open is a thin signal, as our piece on the honest state of open tracking explains, and a change in one person's behaviour tells you more.
• Read a whole search by role. If a search opens well and replies poorly across the board, as in Pin's healthcare figures, the message needs work more than the cadence does.

What Fast Mail Tracker shows a recruiter

Fast Mail Tracker keeps open, click and reply history for each recipient, so you can see which candidates opened, how often and when. It sends one alert for the first open it classifies as human, and opens it attributes to bots or security scanners never trigger it. Two reminders handle the waiting. A not-opened reminder fires when 24, 48 or 72 hours pass with no confirmed human open. A no-reply reminder defaults to 72 hours, can be set to 24 hours or one week, carries a one-click snooze, and stops the moment the candidate replies. For candidate outreach, the one week setting sits close to the six day gap that produced Gem's highest interested rates.

Fast Mail Tracker is in early access while Google's security review completes, so places are limited; to see which candidates are reading and when your next email is due, use the install button below.
