Seventh Sense, built by Telepath Data since 2014, solves a narrow, specific problem: rather than sending an email campaign to every recipient at the same scheduled time, it determines the optimal send time for each individual person based on their own historical email engagement patterns, then staggers delivery accordingly.
That per-recipient timing runs as an add-on layered onto an existing platform like HubSpot or Marketo rather than a standalone email tool itself, meaning a team keeps its existing email content and workflow and adds send-time intelligence specifically on top of what it already uses.
There's no free tier; pricing starts around $64 a month. For a team already using HubSpot or Marketo that wants to improve open rates through better-timed delivery without changing its existing email platform or content workflow, Seventh Sense's narrow, add-on-focused approach to send-time optimization addresses that one specific lever directly.
