How to Find YOUR Best Send Time

Step 1: A/B Test Send Times

Split your list and test different times:

  • Test #1: Morning (9 AM) vs Afternoon (2 PM)
  • Test #2: Winning time vs Evening (7 PM)
  • Test #3: Tuesday vs Thursday

Use Brevo’s A/B testing feature to automate this.

Step 2: Analyze Your Data

Check your email analytics for patterns:

  • Which sends got the highest open rates?
  • What time do most opens occur?
  • Do certain segments prefer different times?

Step 3: Use Send Time Optimization

Brevo and other platforms offer AI-powered send time optimization that automatically sends each email when each individual subscriber is most likely to engage.

Step 4: Consider Time Zones

If your audience spans time zones:

  • Segment by location
  • Use time zone-adjusted sending
  • Or send at a time that works across zones (10 AM EST = 7 AM PST)

Common Send Time Mistakes

  1. Sending at the same time every week — Test and rotate
  2. Ignoring time zones — 10 AM in NYC is 7 AM in LA
  3. Following generic advice blindly — Your audience may differ
  4. Not testing — The only “best” time is the one your data proves
  5. Sending too early/late — Before 6 AM or after 10 PM hurts trust

Quick Recommendations

Just starting? Send on Tuesday at 10 AM in your primary time zone.

Ready to optimize? Run A/B tests for 4-6 weeks, then implement send time optimization based on your data.
