The best time to send LinkedIn messages

The headline finding

Across 800k LinkedIn messages we observed across our customer base in Q1 2026, reply rates varied 2.4x between the worst send-time and the best. That's a meaningful lever for free.

Best windows for B2B outbound: Tuesday 9–11am local recipient time, Wednesday 1–3pm, Thursday 9–11am.

Worst windows: Friday after 2pm, Monday before 9am, weekends, and the 12–1pm lunch hour.

Surprise: Sunday evening 7–9pm shows a 22% reply-rate lift for messages targeting senior executives. They check the inbox before the week starts. Don't send pitchy content; send a thoughtful one-liner.

Local recipient time, not your time

The most common mistake: sending in your time zone, not the recipient's. A San Francisco SDR sending at 9am PST is hitting EU recipients at 6pm — well past the productive window.

Tools that schedule by recipient local time consistently outperform 'send all at 10am' campaigns by 15–25% on reply rate.

Infonet auto-detects recipient time zone from their profile geography and queues sends accordingly.

By seniority

C-suite and VP+: Best windows are unusual — 7–8am, 12:30pm, 7–9pm. They check between meetings and after dinner. They almost never reply mid-meeting (10am–noon, 2–4pm).

Director / Manager: Standard 9–11am, 1–3pm. They have more flexible response windows.

Individual contributor: 9am–4pm broadly. Lunch hour is dead but everything else works.

Day-of-week breakdown

Monday: Below average. Inbox is full of weekend pile-up; your message gets buried.

Tuesday: Best day overall. The 'Tuesday at 10am' folk wisdom is right for a reason.

Wednesday: Strong. Slightly better for senior recipients than Tuesday.

Thursday: Strong. Often best for technical recipients (engineers, ops folks who batch their inbox to mid-week).

Friday: Morning OK, afternoon dead. Don't send after 1pm Friday.

Saturday: Skip. Reply rates ~30% of weekday baseline.

Sunday: Skip morning. Sunday 6–9pm has a niche use for senior-exec targeting if your message is short and curious.

How to actually run this

Don't send all of Tuesday's queue at 10am sharp — LinkedIn's anti-spam systems notice perfectly synchronized send times.

Distribute across the high-reply window (9–11am) with 30–90 second random gaps between sends. Looks human, lands in the productive window.

Cap sends to ~15–25 per hour per profile. Above that LinkedIn flags the burst.

Infonet handles all of the above by default — you set the campaign and the system queues across the optimal windows with human-paced gaps.

FAQ

What about international time zones?

Send by recipient local time. A 10am send for a London prospect is 2am for the SF sender. Tools that don't auto-localize timing are leaving 15–25% reply lift on the table.

Are these times the same for cold email?

Roughly. Cold email reply windows skew slightly later (10–11am instead of 9–11am) because email is checked less actively than LinkedIn's mobile notifications.

Should I batch all my sends to one optimal hour?

No — synchronized sends look like automation. Distribute across the 2-3 hour optimal window with random gaps.
