If your subscribers are located in different timezone and you still like to reach them on the best time of the day this is the option you are looking for.

Mailster sends your campaign at the time you have defined in the campaign options. The time it starts is based on your WordPress timezone settings. This means if you send you campaign at 8 o’clock in the morning some users on the other side of the planet will get it in the middle of the night.

To prevent that and get all mailings in the subscribers inbox in the morning you can check the “Use subscribers timezone”.
On the overview you’ll see a small “24h” sign which indicates this campaign is sending based on the users timezone.

This campaign can take up to 24 hours to finished!

Please keep in mind to send campaigns based on the users timezone Mailster needs to know where they located so you have to enable Geo Tracking in the settings. Furthermore some subscribers location is unknown since there was no interaction yet or their IP address is not in the database. In this case Mailster uses you WordPress timezone setting.
