What Are Smart Send Times?
Smart Send Times is a HubSpot feature that automatically determines the optimal time to send an email to each recipient based on:
- Past open/click behavior
- Engagement patterns
- Time zone differences
Goal:
Maximize opens, clicks, and conversions by sending emails when the recipient is most likely to engage.
How HubSpot Smart Send Times Work
- Data Collection
- HubSpot analyzes a contact’s historical email activity:
- Opens
- Clicks
- Past interactions
- Over time, it builds an engagement profile for each contact.
- HubSpot analyzes a contact’s historical email activity:
- Optimal Send Time Prediction
- Machine learning calculates the time of day and day of the week when a contact is most likely to open and engage.
- Accounts for time zone automatically.
- Email Scheduling
- When creating an email campaign, select “Send at Smart Time” instead of a fixed schedule.
- HubSpot automatically schedules the email for each contact individually.
How to Set Up Smart Send Times in HubSpot
- Navigate to your Marketing > Email > Create Email.
- Create your email content as usual (subject line, body, CTA).
- In the send tab, select “Send at Smart Send Time”.
- HubSpot will analyze historical engagement data for your recipients.
- Review the suggested timing (optional) and confirm.
Tip:
