Prep
You will need to decide if you want to use clicks or opens as your primary metric.
By default this will be set to opens but you can change it by:
- In Dotdigital, navigate to settings > general > account settings.
- Check the use clicks as the primary metric box.
Activate
When you send a new integrated email, check the send time-optimised box:
With this box checked, your email will be sent at the predicted best time to increase engagement over the next 24 hours.
Dotdigital reviews customer engagement data on a rolling 90-days. If a customer has no engagement history yet, the campaign is sent to them straight away.
