Overview

Seventh Sense is an AI-driven email delivery optimization tool that personalizes when each individual recipient receives an email based on their historical engagement patterns. Instead of sending to everyone at the same time, it distributes sends across optimal windows for each contact.

The platform analyzes engagement data from your existing email campaigns to build individual recipient profiles, predicting when each person is most likely to open and click. It works exclusively as an add-on for HubSpot and Marketo.

Seventh Sense is ideal for marketing teams using HubSpot or Marketo who want to improve email open rates, click-through rates, and deliverability without changing their content strategy.
