What is Send Time Optimization?
What does 'Send Time Optimization' mean?
Send Time Optimization (STO) is an add-on function that allows marketers to send emails to each recipient at the most optimal time. In other words, different receivers receive an identical email at various times depending on when they are most likely to engage. Based on past data about their open email timings, the best time for contact is when they are most likely to open an email. If marketers choose to enable Send Time Optimization for an Email step in the Campaign Canvas, the email will be sent an hour before the contact's optimal time. Within a week of starting the email, the email gets sent.
