AI email send time optimization for HubSpot and Marketo campaigns
What is Seventh Sense?
Seventh Sense is a specialized AI tool that optimizes email delivery timing for HubSpot and Marketo users. Instead of sending emails to an entire list at once, Seventh Sense analyzes each contact's historical engagement patterns and delivers emails at the individual-optimal time, spreading sends across personalized windows to maximize open rates, click rates, and deliverability.
The platform's machine learning model builds an engagement profile for every contact based on when they typically open, click, and interact with emails. This per-recipient timing helps avoid inbox competition and spam filter triggers from bulk sending. Seventh Sense also provides email throttling, frequency optimization to prevent fatigue, and engagement scoring to identify database decay.
