Time Zone Optimization
Also known as: Time Zone Targeting, Geographic Send Time
Time zone optimization is automatic scheduling that sends each email at a normal hour in the subscriber's own time zone so messages land when they are most likely to check their inbox. It uses location or time zone data to stagger the send across regions.
Time zone optimization means your email tool sends each message at a normal hour in the subscriber's own time zone. Instead of blasting one send at the same moment for everyone, it lines up delivery to match local time. People in London get the email in their morning, while people in Sydney get it in their morning. The email content stays the same but the send time fits their day.
Good timing keeps your emails near the top of the inbox and helps more people open and click. It lowers the chance that a message arrives in the middle of the night and gets buried under newer mail. Most email platforms can send in the recipient time zone once you store a time zone or country for each contact. You pick a time like 9 a.m. recipient time and the system spreads the send across time zones for you.
You can start by turning this on for regular newsletters or big promotions. Watch open and click rates by country or region to see if timing gaps shrink. If you run global launches or live events, use time zone optimization for reminders but still keep the event time clear in the body. Aim for hours when your audience is awake, working, or taking short breaks.
