Hey, Grow Newsie reader!
Still sending your newsletter at 10 AM on Tuesday because that's what everyone says you "should" do?
I've got news that might change your entire sending strategy.
Here's what the data actually shows:
The Best Day to Send Your Newsletter
Monday is the new champion with a 51.90% average open rate.
Yes, Monday. The day everyone said was "too busy" is now delivering the highest engagement.
Why? Your subscribers are settling into their week, clearing their inboxes, and actually ready to engage with content that helps them tackle the week ahead.
The ranking:
Monday: 51.90% open rate
Tuesday: 51% open rate
Sunday: 51.28% open rate (surprising, right?)
Friday: 50.96%
Thursday: 50.86%
Saturday: 49.93%
Wednesday: 48.62% (hump day slump is real)

The Best Time to Send (This Will Surprise You)
Forget the old 10 AM advice.
The highest engagement now happens between 3 PM - 7 PM on weekdays.
Specific peak times by day:
Monday: 4 PM (53.4% open rate)
Tuesday: 6 PM (52.3%)
Wednesday: 4 PM (52.2%)
Thursday: 7 PM (52.5%)
Friday: 6 PM (52.7%)
People are opening emails when they're winding down work or have already finished for the day.
Weekend sends? If you're brave enough to test it, 7-9 AM shows strong performance with less inbox competition.
Why This Matters for Your Growth
When you send at the right time, you're not just improving open rates. You're:
✅ Getting more clicks and conversions
✅ Building stronger subscriber relationships
✅ Improving your sender reputation

The Smart Approach: Test Your Own Audience
Here's the truth: Your audience might behave differently.
Here's my 3-step testing framework:
Step 1: Start with the data baseline
Try Monday at 4 PM or Tuesday at 6 PM for 2-3 weeks. Track your open and click rates.
Step 2: Test systematically
Run A/B tests changing ONE variable at a time:
Week 1-2: Monday 4 PM vs. Tuesday 10 AM
Week 3-4: Tuesday 6 PM vs. Thursday 4 PM
Week 5-6: Weekday evening vs. Sunday morning
Step 3: Analyze and optimize
Look at opens AND clicks. Sometimes a lower open rate produces higher-quality engagement.
Tools to Automate Your Perfect Timing
1. Smart Sending Features
Platforms like MailerLite and ConvertKit now use AI to send each subscriber your email at THEIR optimal time based on past behavior.
2. Time Zone Delivery
Schedule your send to arrive at 4 PM in each subscriber's local timezone automatically.
3. Auto-Resend to Unopened
Automatically resend to people who didn't open within 24-48 hours with a tweaked subject line.
4. Automation Triggers
Send immediately when someone takes an action (downloads, purchases, clicks) while they're already engaged.
The Mistake Most Creators Make
They obsess over send time but ignore these bigger factors:
❌ Weak subject lines
❌ "From" names that don't build trust
❌ No personalization
❌ Content that doesn't deliver value
❌ Inconsistent sending schedule
Remember: A high-quality newsletter sent at a "suboptimal" time will always outperform a mediocre one sent at the "perfect" time.
Your Action Plan This Week
Check your last 10 newsletters - what day and time did you send them?
Compare your open rates to see if there's a pattern
Pick ONE new time slot to test based on today's data
Set a calendar reminder to review results in 2 weeks
Enable smart sending or timezone delivery if your platform offers it
The Bottom Line
Monday at 4 PM or Tuesday at 6 PM are your new best bets for 2025 based on massive data analysis.
But the BEST time? It's whatever time YOUR specific subscribers are most engaged.
Test, measure, and optimize. That's how you win at newsletter growth.
Keep growing!
