InMail vs connection request vs email for recruiters winning clients

For recruiter client BD, use a connection request for hiring managers in your niche, an InMail for the few you cannot connect with and who matter enough to spend a credit on, and email for everyone with a verified address. LinkedIn credits come back only when the person responds within 90 days. We publish no InMail result.

This post is part of the series on recruitment agency business development. A general comparison of the three first touches already exists in InMail vs connection request vs email. This one is narrower: the person you are writing to is a hiring manager, you probably already pay for a LinkedIn plan built for recruiting, and your list is small and valuable.

How do the three touches compare for a recruiter?

What does an InMail cost?

LinkedIn's own help page, read on 7 November 2026, lists the monthly InMail credits by plan: 5 on Premium Career, 15 on Premium Business, 50 on Sales Navigator Core and 30 on Recruiter Lite. Unused credits accumulate up to a cap that differs by plan (15, 45, 150 and 120 in the same page). LinkedIn's pages give several figures for Recruiter seats that depend on the licence, so check your own plan before you budget.

The rule that matters most for budgeting: LinkedIn credits an InMail back if the recipient accepts, declines or responds within 90 days, and pending messages do not qualify. The Recruiter FAQ adds that a follow up that gets no response does not return its credit either. So an unanswered InMail is a spent credit.

Rough maths, with your own numbers: a Sales Navigator Core seat with 50 credits a month can open 50 hiring managers a month at most, before any credit comes back. A list of 300 hiring managers cannot be opened by InMail alone. This is arithmetic from LinkedIn's page, not a result.

When does each touch fit a hiring manager?

Connection request. The default. It is free, it starts a relationship and the message you send afterwards arrives from someone they have accepted. It suits hiring managers in your niche who use LinkedIn. It is slower, because you wait for acceptance. See the acceptance rate guide for what affects it.

InMail. It fits the person you cannot reach any other way and who matters: the head of engineering at a company you want as a client for years, or a founder with a very selective network. It fits an Open Profile member best, since no credit is spent. It does not fit a mass list.

Email. It fits a verified work address, a longer proposal and a follow up outside the platform. It is also the channel for hiring managers who rarely open LinkedIn. It brings its own rules, covered in GDPR basics for recruiters, and its own limits: Sellinger defaults to 50 emails a day per mailbox.

A decision table for the first touch

Run the table per person, not per list. Many lists need all three outcomes.

Which order works for a typical hiring manager?

A sequence that mixes the channels and never repeats itself:

1. Day 0: connection request, no note, or a one line note.
2. Day 1 to 2 after acceptance: first message on LinkedIn, naming the role.
3. Day 5: email with the same offer and one new fact, if you hold a verified address.
4. Day 10: LinkedIn follow up with a useful offer.
5. Day 18: short closing note on the channel that got the most opens, then stop.

For a strategic target, replace step 1 with an InMail, then use steps 3 to 5 as written. Never send the same text on two channels on the same day.

What do we know about InMail results?

Little, and we say so. Sellinger's InMail first touch is live for all accounts, switched on per account, but we have too few sends to publish a result and we make no claim that it beats a connection request. What we can describe is how it works. The agent opens a lead it is not connected to with an InMail, free for an Open Profile member and one Premium credit otherwise, and falls back to a connection request when no credit or daily slot is left. The default is 10 a day per account, with a maximum of 50. An invite note and an InMail are mutually exclusive on an account, and switching InMail on turns the note off. See the InMail product page and how the agent decides between an invite and an InMail.

What should you test?

Take 150 hiring managers with both a LinkedIn profile and a verified email. Split them into three groups of 50 by random draw: connection request then message, InMail, email. Use the same offer, the same sender and the same weeks. After four weeks count replies and calls held per person messaged. With 50 in a group only a big gap means something. A lot of the value is in what you learn about your own niche, which is worth more than any vendor's claim, including ours.

Where does this leave a recruiter?

Start with connection requests, spend InMail credits only on the people who justify them, and put email behind both. Keep the lists small and the messages specific. For the wording see BD messages for recruiters. For setup and pricing see the recruiter use case and Sellinger pricing: Start $490, Growth $1,490 and Scale $3,900 a month, with five AI colleagues in every plan.
