The honest answer: the best time depends on your audience. Industry benchmarks help you start, but only A/B testing and segmentation tell you what actually wins for your list.
Pro tip: Schedule your send for the recipient's local timezone, not yours. A 10 AM email feels right for an EU subscriber, weird for a US subscriber receiving it at 4 AM.
Industry benchmark windows
| Day | Best window | Notes |
|---|---|---|
| Tuesday | 9 AM - 11 AM | Highest opens for B2B |
| Wednesday | 9 AM - 12 PM | Strong clicks across sectors |
| Thursday | 2 PM - 4 PM | Great for B2C and retail |
| Sunday evening | 7 PM - 9 PM | Works for hobbies, lifestyle, news |
How to find your best send time
- A/B test the same campaign at two different times for two equal segments.
- Track open rate, click-through rate and unsubscribes in real time.
- Repeat 3-5 times with different days and hours.
- Adopt the winning slot — and keep retesting once per quarter.
Times to avoid
- Monday before 9 AM (overflowing inboxes).
- Friday after 4 PM (weekend mode).
- Public holidays in your audience's country.
- The hour right after a major news event in your sector.
