Almost everything written about LinkedIn outreach is opinion: "personalise more", "don't follow up", "InMail is the most professional option". It rarely comes with numbers behind it.
So we opened up ours. This article summarises 12,676 connection invitations sent from HeyTalent campaigns between April and October 2026, plus 686 InMails, and turns them into seven hacks any recruiter can apply to their next search, whatever tool they use.
What is the LinkedIn response rate and how we measured it
The LinkedIn response rate is the percentage of people you contact who write something back after receiving your invitation or your message. In this analysis, a reply is any message from the candidate after the invitation, including "thanks, not right now". It is not an interested-candidate rate.
How the HeyTalent figures were measured:
- Sample: 12,676 connection invitations at least 30 days old, sent between April and October 2026, and 686 InMails sent between July and October.
- Source: real campaigns from recruiters and agencies using HeyTalent, not a controlled experiment.
- What is missing: no breakdown by industry, country or seniority. These are aggregates.
- Correlation, not causation: when we compare groups (with or without a note, one day or another), each organisation writes its own notes and picks its own days. The differences are observations, not guarantees.
The data at a glance
| Metric | Result in HeyTalent campaigns (April–October 2026) |
|---|---|
| Reply rate to connection invitations | 35% |
| Invitations accepted | at least 58% |
| Replies that arrive after a follow-up | 1 in 4 |
| Median time to first reply | 27 hours |
| Replies that arrive in the first week | 78% |
| Reply rate with a note of 150 characters or more | 37% |
| Reply rate without a note | 21% |
| Reply rate to InMails | 17.5% |
Hack 1: don't send invitations without a note
Invitations without a note perform worst in HeyTalent's data. With a note of 150 characters or more, 37% of candidates replied; with a note under 150 characters, 28%; with no note, 21%.
| Invitation type | Invitations | Acceptance | Reply |
|---|---|---|---|
| No note | 896 | 53.0% | 21.0% |
| Note under 150 characters | 657 | 61.5% | 27.7% |
| Note of 150 characters or more | 11,123 | 58.2% | 36.8% |
Notice one detail: acceptance barely changes across the three groups, but replies do. The note doesn't so much decide whether people accept you as whether they answer you. An accepted invitation with no conversation is one more contact in your network, not a candidate in your pipeline.
What to put in those 150+ characters so the note does its job:
- Why this person: a specific reference to their experience, not "I came across your profile".
- What you're offering: industry, type of role or level of responsibility, even if you don't name the client.
- An easy question to answer: "Would you like me to tell you more?" works better than "can we talk for 30 minutes?".
If you want templates to get started, how to automate LinkedIn messages has examples by profile type.
Hack 2: always schedule at least one follow-up
One in four replies arrives after a follow-up message. In HeyTalent campaigns, 26.4% of invitees replied before any follow-up and another 8.8% did so after at least one.
Put the other way round: if your process ends at the invitation, you are leaving out a meaningful share of the conversations your campaigns could open. The follow-up doesn't have to be pushy. It works best when it adds something new:
- A detail about the role that didn't fit in the note: salary range, work arrangement, team size.
- A change of angle: if the note talked about the project, the follow-up can talk about the manager or the growth path.
- A graceful way out: "if now isn't the right time, just tell me and I won't write again" also gets replies, and a clear no saves you time.
Hack 3: give it a week before writing someone off
The median time to first reply is 27 hours in HeyTalent campaigns, and 78% of replies arrive within the first 7 days.
Two practical consequences for recruiters:
- Don't panic on day one. Someone not answering within a few hours is normal: half of all replies take more than a day.
- After the first week, the odds drop. That's a good moment for the follow-up from hack 2, or to move on to the next profile on the list instead of waiting.
If you're working an urgent search, this figure tells you when to launch: inviting your key candidates today gives you almost the whole reply window before next week's meeting with the client.
Hack 4: connection invitation first, InMail second
InMails sent from HeyTalent campaigns got a 17.5% reply rate, compared with 35% for connection invitations. That's half, with the same definition of a reply and the same database.
| Channel | Messages analysed | Reply | Cost to the recruiter |
|---|---|---|---|
| Connection invitation with follow-up | 12,676 | 35% | Included in your LinkedIn account, with a weekly limit |
| InMail | 686 | 17.5% | Uses InMail credits |
An important caveat: InMails are mostly used on profiles you can't invite, so they don't compete on equal terms. The hack isn't "never use InMail", it's don't spend InMail credits on profiles you can invite. Keep InMail for when an invitation isn't possible, and check how InMail credits work before buying more.
Hack 5: try sending at the weekend too
In HeyTalent's data, invitations sent at the weekend got slightly more replies: 39% on Saturday and 42% on Sunday, compared with between 33% and 37% from Monday to Friday.
| Send day | Invitations | Reply |
|---|---|---|
| Monday | 1,985 | 33.0% |
| Tuesday | 2,716 | 36.0% |
| Wednesday | 2,539 | 36.8% |
| Thursday | 2,491 | 34.2% |
| Friday | 1,908 | 33.1% |
| Saturday | 731 | 38.6% |
| Sunday | 306 | 42.2% |
Treat it as a lead, not a rule: the weekend sample is much smaller and only a few organisations send then. A reasonable hypothesis is that passive candidates browse LinkedIn more calmly outside working hours. If your tool lets you choose your send days, it's worth testing in one campaign and comparing.
Hack 6: track acceptance, but optimise for replies
At least 58% of invitations sent from HeyTalent campaigns were accepted. That's a floor, because not every acceptance gets recorded.
The gap between the 58% who accept and the 35% who reply is the metric that tells you most about a campaign. A recruiter with high acceptance and few replies has a messaging problem, not a targeting problem: people let them into their network but see no reason to answer. That's where hacks 1 and 2 come in.
To track it in your own process, three numbers per campaign are enough:
- Acceptance: invitations accepted / invitations sent.
- Reply rate: candidates who reply / invitations sent.
- Reply after follow-up: replies that arrived after a follow-up / total replies.
This is where automation saves the most time: HeyTalent's LinkedIn outreach automation sends the invitation with a note, schedules the follow-ups, spreads sends across the days and hours you choose, and logs every reply in a shared inbox so these metrics come out on their own.
