Send Time Optimization (STO) allows you to put your emails into your recipients' inboxes at the time they are most likely to check their email. When sending a campaign with Send Time Optimization, the system will calculate the best time to send your campaign to each recipient based on their past click and open behavior.
Send Time Optimization functionality is applicable to Regular and A/B Test campaign types. Availability depends on your license. For more information on license packaging, please visit https://www.delivra.com/pricing or email our Client Success team.
