Data Analysis
Best Time to Send LinkedIn Messages
We analyzed data from multiple studies covering millions of LinkedIn messages. Here's when to send for maximum response rates — and what actually matters more than timing.
TL;DR — The Quick Answer
Best day: Tuesday (6.90% response rate), followed by Monday (6.85%)
Best time: 9-11 AM in recipient's timezone
The twist: LinkedIn's own data says timing matters less than you think. Message length and personalization have 2-3x more impact on response rates.
💡 Insight
Expert Insight
Analysis of 1M+ LinkedIn messages shows timing accounts for only ~10% variance in response rates. The difference between the best day (Tuesday, 6.90%) and worst day (Friday, 6.20%) is just 0.70 percentage points.
Key Takeaway: Message personalization and relevance have 2-3x more impact than timing. A poorly targeted message sent at 9 AM Tuesday will underperform a highly personalized message sent Friday afternoon. Optimize for quality first, timing second.

Sunday Surprise
Sunday has lower volume but decent rates due to low competition. Some sales pros use this as a "hidden gem" day — messages sit at the top of inbox when Monday arrives.
Tuesday has the highest response rate (6.90%), followed by Monday (6.85%). However, the variance is only ~10% between best and worst days. Message quality matters far more than which day you send. Sunday sees lower volume but messages sit at the top of inboxes Monday morning.

The Truth: What Matters More Than Timing
LinkedIn's own research conclusion:
"There is no best time. Any time of day gets fairly the same response rate because candidates respond only when it's convenient for them. What really drives response rates is length and personalization."

What Actually Moves the Needle
+65% — More Replies
Messages 25-50 words vs. longer ones
+22% — Response Rate
InMails under 400 characters
2x — Higher Rates
Personalized vs. template messages
Timing accounts for only ~10% variance in response rates. LinkedIn's own research: "Any time gets fairly the same response rate." What actually drives results:+65% more replies for 25-50 word messages, +22% responsefor under 400 characters, and 2x higher rates for personalized messages. Optimize message quality before obsessing over timing.
Practical Recommendations
1. Use Recipient's Timezone
9-11 AM works best, but only in their timezone. Sending at 9 AM EST to someone in London means it arrives at 2 PM. Adjust accordingly.
2. Prioritize Message Quality Over Timing
A personalized message at 3 PM outperforms a generic template at 9 AM. Focus energy on what you say, not when you say it.
3. Avoid Weekends for Time-Sensitive Outreach
If you need quick responses, stick to Tuesday-Thursday. Weekend messages have 2x longer response times.
4. Test Your Specific Audience
General data is useful, but your ICP might differ. Track your own response rates by send time and optimize.
