FAQs

Send-time optimization is a feature that automatically delivers each email at the predicted best time for every individual contact, instead of sending to your entire list at a single fixed time.

The system analyzes historical engagement signals such as opens, clicks, and time zones to identify patterns, then predicts and schedules future sends during each contact’s highest-likelihood engagement window.

Use send-time optimization for newsletters, promotional campaigns, and nurture sequences where maximizing engagement is the primary goal, rather than hitting a precise clock time for all recipients.

Yes, send-time optimization can be applied to one-off broadcast campaigns as well as recurring or triggered automation flows, so each message in a series goes out at that contact’s ideal time.

Yes, you can define boundaries like allowed days, hours, or a send window (for example, “within the next 24 hours”), and the system will choose the optimal time per contact within those constraints.
