Seventh Sense

Seventh Sense is an AI email delivery optimisation system built exclusively for HubSpot and Marketo users. The product solves a single, highly specific problem: it does not write emails, manage content, or run sequences. Instead, it analyses each contact in a database individually and determines the optimal send time and frequency to maximise engagement for that specific person. The AI builds a behavioural profile for each contact based on historical open and click patterns, then staggers email delivery throughout the day to reach each recipient at their personal peak engagement window. Telepath Data, Inc. has operated Seventh Sense since 2013, making it one of the longest-running AI email optimisation tools in its niche. The product is used by B2B marketing teams running HubSpot Pro or Enterprise and Marketo Engage at companies sending high-volume email programmes to large contact databases. Integration depth is deliberately narrow by design. HubSpot and Marketo are the only two supported platforms, and Seventh Sense is built exclusively on top of both. For HubSpot, the integration syncs contact engagement history bidirectionally: historical open and click data flows into Seventh Sense to build per-contact models, and send-time decisions flow back into HubSpot's sending infrastructure. For Marketo, the same model applies using Marketo Engage as the underlying ESP. No third-party platform connection, Zapier integration, or API endpoint for other ESPs exists. No MCP (Model Context Protocol) server support as of June 2026. Notable gaps: no Salesforce Marketing Cloud support, no Klaviyo support, no ActiveCampaign support, no Mailchimp support. Teams not on HubSpot or Marketo cannot use Seventh Sense under any circumstance. Pricing is publicly visible on dedicated HubSpot and Marketo pricing pages via interactive contact-count sliders. HubSpot pricing starts at $80 per month for 5,000 marketing contacts and scales with database size. Marketo pricing starts at $450 per month for 50,000 leads and scales similarly. Both pricing pages allow buyers to see exact prices for their contact count without a sales call. At 500,000+ contacts on HubSpot or similarly large Marketo databases, pricing shifts to custom enterprise quotes requiring a sales conversation. The Seventh Sense subscription is additive to existing HubSpot or Marketo platform costs: teams pay for both their underlying ESP and the Seventh Sense layer on top. A free trial is available for both platforms. Who Seventh Sense is not for: teams not on HubSpot or Marketo. Salesforce Marketing Cloud users, Klaviyo users, Mailchimp users, ActiveCampaign users, and all other ESP users cannot use this product under any circumstances. Teams expecting content improvements, subject line optimisation, or list quality enhancements should look elsewhere: Jasper (from $49/month) for AI content generation, Persado for language optimisation, or Klaviyo's built-in AI features for e-commerce email. Teams wanting a full email marketing intelligence suite should evaluate HubSpot Marketing Hub's native AI features included in Pro (from $800/month) or Salesforce Marketing Cloud Einstein before adding a specialist send-time layer. Teams with fewer than 5,000 HubSpot marketing contacts or fewer than 50,000 Marketo leads are below the minimum thresholds for Seventh Sense's pricing calculator.
