Should you add a note to a LinkedIn connection request?

Short answer

For cold sales outreach, usually no. A blank request gets accepted about as often as one with a note, and often slightly more. Add a note only when you have a real, specific reason this person should know who you are, and never pitch in it. The note doesn't earn you the connection. What it can do is make your first message after acceptance land better.

That's the conclusion from the three biggest public tests I could find. None of them is academic research: they come from outreach tool vendors, who have a stake in you sending more requests. But they measured large samples, they mostly agree with each other, and they agree with what you see when you run campaigns by hand.

What the data says

Belkins looked at 11.5 million connection requests sent across 2025. Requests without a note were accepted 27.6% of the time, requests with a personalized note 25.3%. But replies went the other way: 8.2% of people who got a note eventually replied, against 5.3% without one (Belkins study).

Waalaxy ran a study of over 10,000 invitations and broke the note down by type (Waalaxy):

La Growth Machine tested three audiences of marketing managers, brand directors and CMOs, about 9,000 people in total (La Growth Machine). No note: 31% accepted. An honest sales note: 29%. A vague, friendly note: 32%. The interesting number is further down the funnel. Qualified calls booked were 3.77% for no note, 6.62% for the honest sales note and 5.1% for the vague one.

Put together, the pattern is clear:

• The note moves acceptance by a couple of points at most. Usually down.
• Links and long text hurt acceptance the most.
• A note that tells the person why you're writing can improve what happens after acceptance: replies, calls.

Decide what you are optimizing for. If it is the size of your network, send requests blank. If it is booked calls, a short honest note can pay for the lost acceptance.

When to skip the note

Skip it when you're connecting at volume with people who don't know you and you'll send a real message right after they accept. That covers most outbound. You keep the higher acceptance, and you spend your words in the first DM, where you have up to 8,000 characters and the person has already said yes to hearing from you.

Skip it on a free account too, for a practical reason. LinkedIn's help page on personalizing invitations says free members can add a personal message to only a few invitations a month, while Premium members aren't limited in the same way (LinkedIn Help). LinkedIn has changed that number more than once, so check the Add a note screen in your account. If you only get a handful, save them for the people where context really matters.

When the note earns its place

A note pays off when it gives the person a reason to recognize you, not a reason to buy:

• You met, spoke on the same panel, or were in the same thread.
• A mutual contact suggested you connect.
• They posted something specific you're responding to.
• They're a senior person who gets dozens of requests and filters out strangers.
• You're re-engaging someone who already knows your company.

In all five, the note answers the silent question "who is this and why me?". That's the only job it has.

Notes that don't read like a pitch

The limit is 200 characters on LinkedIn's current help page, so you have about two sentences. Here are five I'd send, one per situation above:

Hi Anna, we were both on the fintech ops panel at Money20/20 on Tuesday. I liked your point about manual KYC queues. Happy to stay in touch.

Hi Tom, Priya Shah suggested we connect. She mentioned you're hiring your first SDRs in Berlin; we just went through the same thing.

Hi Laura, your post on dropping cold calls for warm intros got me thinking. Curious how it's going two months in.

Hi David, I run partnerships at a 20-person data agency. We work with a few logistics teams like yours. Connecting so I'm not a stranger later.

Hi Sam, we spoke last spring about your Shopify migration. Saw you moved to Acme, congrats. Would be good to stay connected.

What these have in common: a first name, one specific fact, no link, no question that demands work, nothing to buy. The fourth one is closest to sales, and it's honest about it. That's the version La Growth Machine's test favored for booked calls.

The message after acceptance matters more

Whichever way you go, the real work starts when they accept. A blank request followed by a sharp first message beats a clever note followed by "Thanks for connecting! Let me tell you about us." Write the first DM about them, ask one easy question, and keep it short. I covered what to put in it in what to say after a LinkedIn connection is accepted.

Two more things decide whether the channel keeps working. Pace: send too many requests a week and LinkedIn starts restricting the account, so stay within the numbers in how many LinkedIn connection requests per week is safe. And replies: someone who accepts and answers your first message on a Friday night should not wait until Tuesday.

Running it without losing the thread

Doing this by hand works for twenty requests a week. At a hundred, the notes turn generic, the first messages go out late, and replies sit in a LinkedIn inbox nobody opens.

Nitrino handles that part. In a campaign you choose whether LinkedIn requests go out blank or with a short note, it keeps daily and weekly invitations inside the account's limits, writes the first message to each person who accepts, separately and in the account owner's voice, and answers their replies alongside email, Telegram and WhatsApp. When a reply needs your decision, it hands the conversation to you. Whatever you use, the order stays the same: a clean request, a good first message, and an answer when they write back.
