Send a regular LinkedIn message when the prospect is already a 1st-degree connection, and use InMail when they sit outside your network and you have a reason that cannot wait for a connection request to be accepted. That is the whole of LinkedIn InMail vs. messages as a channel decision. The harder question is which contact has earned a message from you today, and a recent public signal, a role change, funding news, a post about the problem you solve, answers both at once.
TL;DR
- Regular messages reach 1st-degree connections and members with an Open Profile, InMail reaches contacts outside your network, and InMail requires a Premium subscription while regular messaging is free.
- A prospect can switch off InMail in their message preferences, so delivery is never guaranteed, whereas a 1st-degree connection cannot opt out of messages from you.
- The channel question only feels hard when you have no reason to write. Pick the prospect by signal first and the channel follows in about two seconds.
- Tealde ranks your leads and attaches the signal that moved them, then drafts a first touch if you want one. You decide who gets the message.
How did we compare them?
We compared the two channels on the things that actually change your day as an SDR or AE, not on feature lists. Four criteria, plus cost.
- Who you can reach. Does the channel work for a contact you have never spoken to?
- Whether it lands. Can the recipient stop your message from arriving at all?
- How cold it feels on arrival. Does the prospect already have context for your name?
- What it costs you to send. Money, and the scarcer resource, your own judgment about who is worth it.
- Pricing. Free versus paid, without quoting plan prices that change.
How LinkedIn InMail vs. messages compare on reach, delivery and cost
Comparison current as of June 2026:
| Criteria | Regular LinkedIn message | LinkedIn InMail |
|---|---|---|
| Who you can reach | 1st-degree connections, plus members with an Open Profile | Contacts outside your network, no connection request needed |
| Can the recipient block it | A 1st-degree connection cannot opt out of your messages, short of blocking you | Yes. A member can turn off InMail in their message preferences (LinkedIn Help (opens in a new tab)) |
| How cold it arrives | Warmer. They accepted you at some point | Cold by default unless your first line gives them a reason |
| What it costs to send | Free | Credits from a Premium subscription, allotted by tier and renewed each billing cycle (LinkedIn Help (opens in a new tab)) |
| Pricing | Included with a free account | Requires Premium, Sales Navigator or Recruiter |
| Best moment to use it | Follow-up, re-engaging a dormant contact, an account you have worked before | A new name at a target account, where a signal just made them relevant |
What is the difference between a LinkedIn InMail and a message?
A regular message travels inside your network and an InMail travels outside it. A LinkedIn InMail is a paid 1:1 message you can send to a member you are not connected to, without waiting on a connection request. A regular LinkedIn message, the thing most reps call a DM, only reaches your 1st-degree connections or members who have turned on Open Profile.
Then, which one gets read, which one gets a reply, comes down to whether you had something worth saying.
One more distinction worth keeping straight. InMail is person-to-person and comes out of your own subscription. Sponsored Messaging is an advertising product that delivers to an audience segment and is billed through LinkedIn Ads. If you are a rep picking a channel for one named buyer, you are choosing between the first two.
Regular LinkedIn messages: strengths and limitations
The strength of a regular message is that it cannot be refused. Your 1st-degree connections cannot switch you off in their settings. They accepted you, which means your name is not a complete stranger in the inbox, and the thread may already have history you can pick up.
It is also free, which matters less than reps think. The constraint on your week is not message cost. It is how many prospects you can research well enough to say something specific to.
The limitation is reach. Your network is a fixed pool, and the decision maker at the account you have been chasing for two quarters is probably not in it. You can write a sales connection request message, but then you are waiting, and the signal that made them relevant this morning may be stale by the time they accept.
Best for: AEs working existing accounts, re-engaging warm leads who went quiet, and anyone whose territory overlaps heavily with their own network.
Not ideal if: the prospect you need is a new name at a new logo and the reason you are writing is time-sensitive.
LinkedIn InMail: strengths and limitations
The strength of InMail is that it removes the waiting. You spot an outreach trigger, you find the right contact, you write. No connection request sitting unanswered for nine days while a job change goes cold.
It also forces a useful discipline. Credits are allotted by subscription tier and are never unlimited, so you cannot spray. When a send costs something, you check whether the person is genuinely worth it, which is exactly the check most cold outbound is missing.
The limitation is that delivery is not guaranteed. A prospect can turn off InMail in their data privacy settings, and you will not know in advance. The second limitation is harsher: InMail arrives cold. A regular message gets a moment of recognition. An InMail gets about one line before the prospect decides you are a vendor. If that line is generic, the channel will not save it. A generic line usually means you picked the prospect before you had a reason, so LinkedIn message personalization best practices start with who you write to.
Best for: SDRs doing cold outbound into named accounts, where the buyer sits outside the network and a public signal gives you a reason to write now.
Not ideal if: you have no signal and you are working from a list of titles. The channel will just make your low-relevance outreach faster.
How do I decide which prospect deserves a message today?
Two contacts match your ICP perfectly. One of them posted yesterday about the problem you solve. That one gets the message today. The other one waits until something moves, because knowing when to reach out to prospects matters more than the channel.
This is the part Tealde does before you sit down. Your leads are already scored against your ICP, and the ones that moved are already at the top with the reason attached: new role, funding round, a post, a job opening that tells you they are building the team you sell to. You open it, you read the reasons, you pick the five that are worth your morning. Tealde ranks and surfaces. You decide who hears from you, and you write and send the message yourself.
Common questions about InMail and LinkedIn messages
Is InMail free, or do I have to pay for it?
InMail requires a Premium subscription, so there is no free version of it. Credits come with your plan tier and renew on the first day of your billing cycle, and no plan gives you unlimited InMails. Regular messaging to your 1st-degree connections is free on any account.
Can a prospect block or opt out of receiving InMail?
Yes. A LinkedIn member can turn off InMail in their message preferences, and when they have, you cannot reach them that way at all. You get no warning before you send. A 1st-degree connection cannot opt out of your messages the same way, which is one of the quiet advantages of getting connected.
What is the difference between InMail and Sponsored Messaging?
InMail is a 1:1 message to a named individual, paid for through your Premium, Sales Navigator or Recruiter subscription. Sponsored Messaging, also called Message Ads, delivers to an audience segment and is billed through LinkedIn Ads. If you are a rep working named accounts, InMail is the relevant tool. Sponsored Messaging is a marketing buy.
Is LinkedIn messaging better than cold email for prospecting?
Neither channel wins on its own merits, because both are carrying the same variable: whether you have a reason to write. LinkedIn gives you more context about the person and a visible trail of what they care about. Email gives you reach without a network constraint. Most reps get the best results running them together, referencing the same trigger in both.
When should I follow up by email instead of LinkedIn?
Switch to email once LinkedIn has gone quiet after your first touch and a follow-up. Keep the reason identical, reference the same role change, funding round, or post, and keep the ask small. Changing channels is not a reset; it is the same conversation arriving somewhere the prospect checks more often.
Does warming up a prospect before messaging actually help?
It helps, modestly, and it costs you very little. A genuine comment on a prospect's post a few days before you write means your name registers rather than arrives from nowhere. Do it selectively on accounts that matter. Automated liking at volume does the opposite, and Tealde does not do it in any case.
At what team size does channel choice stop mattering?
It stops mattering as soon as more than one rep is working the same territory, because then the real risk is two people messaging the same contact in the same week. At that point the question becomes who owns which account and which signal justified the touch, not whether it went out as an InMail or a DM.
Do I need Premium or Sales Navigator to do this?
You need Premium or Sales Navigator to send InMail, and nothing at all to message your 1st-degree connections. For the selection work, picking who deserves a message today, you do not need a LinkedIn subscription. Tealde scores your leads and surfaces what changed on its own live lead database, and you can ask it who to prioritize in plain language.
