The question comes up the moment you start selling on LinkedIn: how many messages can you send before the platform steps in? It is a fair question, because a restriction always lands at the worst time, usually the day a campaign starts to produce something.
The problem is that the pages answering it give different answers. Compare the top search results and you will find 50 messages a day, 100, 150, 20 for a new account, then 100 a week on a free account against 150 on a paid plan. None of those pages links to a LinkedIn page, for a simple reason: that page does not exist. The gaps between those estimates are the best proof that they are estimates.
So this article does the opposite of the rest of page one. It gathers what LinkedIn puts numbers on itself, in its own help pages and terms. It names exactly what LinkedIn chooses not to quantify. And it offers a way to decide when the number you are looking for was never published.
What LinkedIn publishes, and what it keeps quiet
There is a logic behind the split, and it is easier to see once you lay it out. LinkedIn puts a number on everything you pay for: a subscription comes with a certain number of credits, and that number has to be written somewhere, or nobody would know what they are buying. On the other hand, everything related to abuse detection stays deliberately vague, because a published threshold is a threshold people work around by stopping just below it.
That asymmetry explains why you can find InMail credit details in a few clicks and nothing at all on how many messages you can send to your connections. The first is a price list. The second is a defense. The three families of limits below therefore trigger in different places, for different reasons.
InMail credits: the only quota with real numbers
An InMail is the message you send to a member you are not connected with, and it is the only allowance LinkedIn counts in front of you. On its help page about InMail messages, the platform lists credits by plan: 5 per month for Premium Career, 15 for Premium Business, 50 for Sales Navigator Core, and 30 per month for Premium All in One, capped at 90 in total. Unused credits expire after 90 days, and you get a credit back when the recipient accepts your InMail. In effect, you pay for silence, not for the conversation.
The same page gives the lengths: up to 200 characters for the optional subject line, and up to 2,000 characters for the body. Both numbers are worth knowing before you write, because they are far more generous than most people assume, and a 2,000-character InMail has every chance of never being read.
Above all, remember this: the InMail quota says nothing about the rest. It only covers people outside your network, and it has nothing to do with how many messages you exchange with your existing connections.
Invitations: a real limit LinkedIn never quantifies
This is where most accounts get stopped, and it is also where the documentation turns deliberately vague. LinkedIn's help page on hitting the invitation limit says the restriction usually lasts a week, that withdrawing pending invitations does not lift it, that you cannot buy extra invitations in the meantime, and that support will disclose neither the type nor the reason for the restriction. There is no number on it.
The neighboring page, the one describing the types of invitation restrictions, is even more telling, because it names the causes without ever quantifying them. It lists three situations. You sent a lot of invitations in a short time. Many of your invitations were ignored, left pending, or marked as unwanted by the recipients. And if you send an excessive number of invitations and LinkedIn suspects an automation tool, the account can be suspended or restricted. The words used are "a lot," "excessive" and "a short time," and they stay that way from start to finish.
The second point deserves a pause, because it changes how you should think about this. Your volume is not the only thing that counts: so does the reaction of the people you reach out to. Two accounts sending the same number of invitations do not run the same risk if one gets acceptances and the other piles up ignored requests. One practical detail on top: once you withdraw an invitation, you cannot send it again to the same person for three weeks.
For the note attached to an invitation, LinkedIn does give numbers. Its page on personalizing invitations mentions a note of 200 characters at most, three personalized invitations per month on a free account, and unlimited for Premium members. These figures are not perfectly consistent from one help page to the next. What every page agrees on is simpler: a free account is limited in length and in volume, a paid account much less so.
The commercial use limit, the one that hits before messages
Plenty of accounts hit a wall before sending anything at all, and they cannot figure out why. The commercial use limit is not about messages. It is about searching and viewing profiles, including through the "People also viewed" sidebar and from company pages. When your activity looks like recruiting or prospecting, LinkedIn caps what you can browse for free.
That page is remarkably frank on the point we care about. It says it is not possible to display the exact number of searches or views you have left, and that the limit cannot be lifted on request. It specifies that the free counter resets at midnight Pacific Time on the first day of each calendar month, and that the Premium Business, Recruiter Lite and Sales Navigator plans raise the allowed volume.
What makes this page useful goes beyond its topic: it shows that LinkedIn says so in plain words when it refuses to give a number. So there is no point hunting for some obscure page that would hold the message threshold.
Messages to your connections: no published number
For messages sent to your first-degree connections, LinkedIn publishes no daily cap, no weekly cap, and no visible counter. That is the honest answer to the question this article opened with. It is disappointing, but it beats a number that would be wrong for your account.
Instead of a threshold, LinkedIn describes behaviors. Its Professional Community Policies prohibit messages that are untargeted, irrelevant, obviously unwanted, unauthorized, or needlessly repetitive, and they ask you not to use the invitation feature to send promotional messages to people you do not know. The User Agreement goes further on the means used: it bans bots and other unauthorized automated methods to access the service, add contacts, or send and redirect messages, and it also bans getting around the platform's usage limits.
That last point matters if you are considering a tool, and it reads both ways. What LinkedIn targets is sending done by a program in place of a person, along with workarounds of its own limits. A message written for a specific reason is the opposite of a batch send. Something like this:
Hi Mark, you mentioned in June you were waiting for Q4 budget before hiring a coach. Is that still on the table?
A message a human reads and decides to send is not in the same category as a queue that empties itself overnight. That is exactly the distinction we lay out elsewhere when looking at what actually triggers an account restriction. Across platforms, it is behaviors that get punished far more often than the software itself.
How to decide when no number is authoritative
Since the number does not exist, you have to reason differently, and LinkedIn's pages give enough material for that. They name four signals you can actually control, where an imaginary cap tells you nothing about your own account.
- Volume packed into a short window. A hundred invitations sent within an hour looks like nothing a human would do, whatever the weekly total.
- Acceptance and reply rates. Ignored or reported invitations weigh more than their count, since LinkedIn names them as a cause of restriction.
- Identical repetition. The same text sent to a hundred people is the easiest pattern to detect, and the oldest.
- Opening conversations with strangers, which is the very purpose of the InMail allowance and the invitation cap.
None of these four signals goes off when you reply to someone who wrote to you, or when you pick up a conversation with someone who accepted your invitation six months ago. The same asymmetry holds on other channels, and we break it down in our piece on follow-up vs cold outreach. On pacing itself, what we wrote about follow-up cadence applies here as is: sends spread over the day look like someone working through their inbox, a burst looks like a program.
In practice, that gives you a rule of conduct that holds without a number. Start with people who have already answered you at least once. Write messages that are truly different from one another. Spread sends across the day instead of emptying a list. Watch your invitation acceptance rate rather than your weekly total. If you absolutely want a number to start with, take the one you would handle yourself by hand on an ordinary weekday, and treat it as a personal cap rather than a permission from the platform.
Where Ficiel fits in this picture
Ficiel works on threads that are already open. On LinkedIn, that means accepted invitations that went nowhere, conversations cut off after a few exchanges, calls that were mentioned and never booked. None of these consumes an InMail credit, because none of them means writing to strangers. The idea of mining that backlog is the subject of our guide to following up with old conversations.
Kord is Ficiel's AI assistant: it rereads your conversations, finds the leads who went quiet, drafts follow-ups in your own voice, and a human always approves before anything is sent. That last step is not window dressing. It is what separates a person sending their own messages from a program sending them in their place, the very line LinkedIn's User Agreement draws.
It is also worth saying what this setup does not do. It does not shield you from a restriction, because LinkedIn decides alone and publishes neither its thresholds nor its reasons. Nobody can promise you otherwise, and a page that does, in exchange for a subscription, should worry you more than the limits themselves. What is in your hands comes down to writing to people who know you, in your own words, at a pace you could keep up by hand.
FAQ
What is Ficiel?
Ficiel is an AI inbox for coaches and setters: it surfaces old Instagram, WhatsApp and LinkedIn conversations worth following up, drafts the message, and nothing is sent without your approval. On LinkedIn, that covers accepted invitations with no follow-through as well as conversations that stalled after a few exchanges.
How many messages can you send per day on LinkedIn?
LinkedIn publishes no number, per day or per week, for messages sent to your connections. The figures you find online come from tool vendors and contradict each other. The platform describes behaviors to avoid, such as concentrated volume, identical repetition and unsolicited messages, but it gives no threshold.
How many InMails per month does each plan get?
According to LinkedIn's help page on InMail: 5 per month for Premium Career, 15 for Premium Business, 50 for Sales Navigator Core, and 30 per month for Premium All in One, capped at 90. Credits expire after 90 days and are returned to you if the recipient accepts your message.
Why was my account restricted when I did nothing unusual?
LinkedIn names three causes: many invitations in a short time, many invitations ignored or marked as unwanted, and suspected use of an automation tool. The second one surprises people most, because it depends not on your volume but on how the people you contacted reacted. The restriction usually lasts a week, and withdrawing pending invitations does not lift it.
Does the commercial use limit apply to messages?
No. It applies to searching and viewing profiles, not to sending. That is why you can hit it without having written to anyone. LinkedIn says it does not display the exact number of views you have left and does not lift the limit on request.
Does replying to someone count toward the limits?
The allowances LinkedIn puts numbers on, InMail credits and invitations, concern people outside your network or not yet connected with you. Replying in an existing conversation uses neither, and shows none of the signals the platform names as causes of restriction.
