Seventh Sense

Seventh Sense is an email performance management system focused on improving when and how often emails are delivered, built specifically for HubSpot and Marketo environments. The company describes its AI as personalizing delivery time for each individual, and it also emphasizes audience engagement management, which aims to protect list health by adjusting sends based on engagement signals rather than blasting the full database. This positions Seventh Sense as more than simple send time optimization, because it links delivery timing to engagement strategy and audience hygiene. Operationally, the product works as an add on that influences how campaigns and workflows execute in HubSpot or Marketo, so fit depends on your marketing ops maturity and your ability to segment and govern email programs. Pricing is published on the official site for HubSpot packages, with a business tier shown at $80 per month billed annually including 5,000 marketing contacts, and additional contacts purchased in increments. For evaluation, measure lifts in opens and clicks with proper controls, and track complaint and unsubscribe rates to confirm engagement health effects. Also validate workflow behavior such as delivery windows and execution constraints, because timing decisions can interact with HubSpot workflow schedules. Seventh Sense is best for organizations that send enough email for timing and fatigue to matter and that want an AI layer designed around HubSpot or Marketo rather than generic ESP add ons.
