Seventh Sense
Seventh Sense is an email performance layer for HubSpot and Marketo that schedules each message to the individual contact's best open time. It connects to your existing marketing automation stack and adds send-time optimization, audience recycling, campaign orchestration caps, and deliverability insights without replacing your ESP.
Most send-time tools pick one window for the whole list. Seventh Sense profiles each contact, suppresses worn-out subscribers, and coordinates sends across campaigns so you stop colliding with your own emails. The Business plan includes all four AI capabilities, unlimited users, and engagement profiles written back to HubSpot CRM records.
Seventh Sense has served HubSpot and Marketo customers since 2014 and reports 500M+ personalized emails orchestrated monthly. Marketing teams at financial, energy, consulting, and pharma brands use it when batch-and-blast fatigue is hurting inbox placement.
