Optimize marketing email send time

By optimizing when you send a marketing email based on when contacts have opened or clicked recent emails, you can improve your chances of generating engagement for the current email. 

In the email editor, you can generate a suggested time based on an average of best sending times for that email's recipients.

In accounts with a Marketing Hub Enterprise subscription, you can also set a marketing email to be sent to each individual contact at their own best time, calculated from their recent email opens and clicks.

Understand limitations and considerations

• Recent engagement is calculated by looking at each contact's email opens and clicks for the past 90 days. 
• One-to-one emails and opens categorized as bot activity will not be included when calculating recent email engagements. 
• Sending time is calculated using your user's time zone. 
• When optimizing send time for individual contacts, contacts without enough engagement data will be sent the email at the beginning of the sending range.
• When optimizing send time for individual contacts, you can set a sending range of up to 168 hours, or seven days. This applies to both emails sent immediately and those scheduled for later.
