## Frequently Asked Questions
### Does send time really matter that much?
Yes, send time can impact open rates by 40-60% and response rates by 25-35%. The difference between optimal and poor timing often determines campaign success or failure.
### Should I send emails in my timezone or the recipient timezone?
Always use recipient timezone when possible. Sending at 10 AM in their local time consistently outperforms sending at your convenient time by 30-40%.
### What if I have a global audience across multiple timezones?
Segment your list by timezone and send campaigns at optimal local times for each region. Most email platforms can handle this automatically.
### How do I handle different industries in the same campaign?
Either segment by industry for optimal timing, or use the universal best practice of Tuesday-Thursday, 10 AM - 2 PM in recipient timezone.
### Does the day of the week matter more than the hour?
Both matter significantly. Day of week affects whether your email gets attention (Tuesday best, Friday worst), while hour affects the quality of that attention (10 AM - 2 PM peak).
### How often should I test different send times?
Test send times quarterly or when you notice performance changes. Major timing shifts (different day or 4+ hour changes) should always be tested before full implementation.
