Connection notes that get accepted

The connection note is the cheapest experiment in B2B outreach. You get one shot at 200 characters. You will know within 48 hours whether it worked. If you get this part right, the rest of your outbound becomes easier; if you get it wrong, every later step inherits the damage.

We have looked at thousands of connection notes that Funkel agents have sent across the early customer cohort. Three things show up in every note that gets accepted, and three things show up in nearly every note that does not.

The hard constraint

LinkedIn caps notes at 200 characters on free accounts and 300 characters on Premium. Funkel’s default prompt asks Claude to write exactly one sentence; we picked one because two sentences almost always blow past the limit and get truncated awkwardly mid-word.

If you are writing manual notes, set yourself the same constraint. One sentence. The discipline forces you to decide which thing matters most, and it produces notes that sound like a real person sent them, not a prospecting tool.

Three things that work

1. Cite the signal that triggered the outreach

The buyer cannot tell whether you noticed them via a spreadsheet of 10,000 names or a real moment that just happened. Tell them. “Saw your post about replacing Outreach” lands different from “Came across your profile.” The signal does not have to be flattering or specific to them as a person; it just has to be real.

2. Skip the “hi”

You do not have a budget for greetings. “Hi {first_name}” eats 10 to 14 of your 200 characters and adds nothing. Open on the signal. The buyer’s name will be in the connection request header anyway.

3. End on a question or a clear next step

Notes that end on a hook (“curious how you handled the switch”) outperform notes that end on a statement (“happy to chat”). The buyer has a reason to accept beyond politeness; replying becomes the obvious next move once they are connected.

Three things that quietly hurt

1. The compliment opener

“Loved your post on...” is the cold-outbound watermark. Buyers see it ten times a week. If your note opens this way, even the people who would otherwise have accepted will hesitate.

2. The pitch in the note

Notes that try to sell the product before the buyer has accepted underperform consistently. The connection request is not the close. Save the pitch for the message after they accept; you will have 8000 characters then.

3. Em dashes and dashes-as-pause

Em dashes show up overwhelmingly in AI-generated copy and rarely in real human writing. They are the single fastest tell that a note is automated. Funkel’s AI prompt explicitly bans them. If you write notes manually, ban them too.

Two examples

What does not work:

Hi Mira, loved your recent post on the future of GTM, would be great to connect and learn more about what you’re working on at Acme.

What does:

Saw your post about ripping out Outreach. Curious which piece you replaced first. We just shipped a different way to think about the same problem.

Same character count. Different note. The second one starts on the buyer’s decision, asks a question, and offers a hook for the next message. It also reads like a person, not a sequence.

The cumulative point

A connection note is a 200-character compression of the question “why now, why me?”. If you can answer both inside the limit, your accept rate rises by enough to change the math on the entire campaign. If you cannot, no amount of follow-up cleverness saves it.
