By Most LinkedIn message sequences are email sequences with the logo changed. Five touches. Two or three days between each. Every message a little more apologetic than the one before it. I ran that playbook for months before I looked at when replies actually show up, and the schedule stopped making sense.
Across 2,511 messages sent through Linkdify in August and September, the reply rate was 14.6%. The number that changed how I think about sequencing wasn't the rate. It was the timing. The median reply came in about 14 hours. Most replies landed within the first day. Not the first week. The first day. (Full numbers here.)
LinkedIn is a chat app, not an inbox
Email follow-ups exist because email gets buried. Your first message sinks under forty others by lunch, and a "bumping this" three days later genuinely surfaces it. That logic is sound. For email.
A LinkedIn message is different. It shows up as a red badge on someone's phone. It sits in a short list with maybe a dozen other threads, most of them recruiters. The person sees it within hours. They open it or they don't, and either way they've made a decision about it by the end of the day.
So when you send "just circling back" on day three, you're not rescuing a message from a pile. You're re-sending something they already saw and chose not to answer. Silence on LinkedIn is rarely a scheduling problem. It's feedback.
What the 14-hour window means for your sequence
I'm not saying never follow up. I'm saying the follow-up has a different job than most people give it.
Your second message cannot be a reminder. If the first message had a day to work and didn't, repeating it with "any thoughts?" bolted on won't change the outcome. The second message has to be a new attempt: a different angle, or a question about something they posted last week that wasn't in message one. If you don't have a second thing to say, don't send a second message.
Space it out further than feels comfortable. I don't have a dataset that proves the perfect gap, so take this as an operator's opinion rather than a benchmark. But if replies cluster in the first day, then touches on day two, four, and six are mostly hitting people who've already passed. Those messages don't just fail. They teach the person that your name means noise. A week or two of quiet, then one genuinely different message, respects the signal they already gave you.
The first message carries almost all the weight. This is where I'd put the effort you're currently spreading across five steps. One well-aimed message, written for someone reading it on a phone between meetings, beats five decent ones. Keep it short, with one clear reason you're writing and one easy way to respond.

The same pattern shows up one step earlier
The connection request taught me the same lesson from a different direction. Across 8,400 requests, acceptance averaged 25.2%, about one in four. Split by whether a note was attached, the gap was enormous: 48.6% accepted with no note, 8.6% with one.
I used to read that as "notes are bad." I now read it as "people decide fast, and pitching before you've been let in makes the fast decision a no." The request is a doorbell. The note is you starting your pitch through the door. The first message after acceptance is the actual conversation, and that message gets roughly a day to land.
Put together, the whole funnel is a series of quick decisions. Almost nobody is sitting on your request for a week weighing it. Almost nobody saves your message to think about over the weekend. Design for that.
Where automation makes this worse
Most LinkedIn tools, including mine, let you build a multi-step sequence with delays between steps. That's the right primitive. The problem is what people fill it with. The sequences I see founders bring in are still the email cadence: message, bump, bump, breakup. Run that on autopilot and you spend your account's daily message allowance on threads that went cold a day after they opened.
I'd also bet those dead-thread bumps look a lot like spam from LinkedIn's side. A long string of unanswered messages from one account to many people is exactly the pattern that draws attention. You pay for the follow-ups twice: once in wasted sends and once in account risk.
When I set up a campaign in Linkdify now, I push the first message hard and keep the sequence short. The follow-up, when there is one, waits long enough to be a fresh start and says something the first message didn't. And I watch reply timing, not just reply rate. If replies are arriving in hours, the first message is doing its job. If they've slowed to days, the first message is weak and later steps are propping it up. Fix the first message.

Write it like it has one day to work
That's the whole takeaway. Treat every LinkedIn message as if it gets about a day to earn a reply, because in my data that's roughly what it gets. Spend your effort on the message that goes first. Make the follow-up a new reason, not a nudge. And when someone has gone quiet for a day, believe them.
