Per-person email send time optimization, for HubSpot and Marketo only
Seventh Sense builds per-person send time models from engagement data, publishes its pricing at 400 USD a month for 25,000 contacts and charges no seat fees. It integrates with HubSpot and Marketo only, and its public material does not address how Apple Mail Privacy Protection affects the open data those models learn from.

Seventh Sense features: what it does
- Pricing is published at 400 dollars a month for 25,000 contacts, with no per-seat fees, no overage charges and unlimited users
- Deliberate narrowness, being built for HubSpot and Marketo and explicitly nothing else, produces depth most integrations lack
- Per-person timing models rather than a single best send time for a whole list, which is the version of this idea that can actually work
- More than 1,000 customers on two platforms, including SAP, Demandbase and Greenpeace, is genuine concentration rather than thin breadth
Seventh Sense limitations
- Apple Mail Privacy Protection is not addressed anywhere in the public material, despite prefetching having made open data unreliable for exactly the signal this product learns from
- Per-person models need substantial history per contact, and no minimum is published
- Supporting only two platforms means switching ESP means losing the tool entirely
- At 400 dollars a month for 25,000 contacts, the cost sits alongside the ESP fee rather than replacing anything
Who Seventh Sense is for
| Your situation | What that means here |
|---|---|
| HubSpot or Marketo team with a large list | Twelve years on two platforms buys depth that broad integrations sacrifice, and this is the intended deployment. |
| B2B sender across many time zones | Per-person timing beats a single best hour precisely when audiences span working patterns. |
| Team on any other ESP | Nothing else is supported by design, so the product simply does not apply. |
| Sender with a small or infrequently mailed list | Per-person models need observations per contact, and monthly sends to 25,000 give each person twelve a year. |
| Buyer who values pricing transparency | 400 dollars a month for 25,000 contacts, no seat fees, no overages, unlimited users. |
| Team with deliverability problems | If the issue is sender reputation rather than timing, this addresses the wrong variable. |
Seventh Sense use cases for marketers
- Lifecycle and nurture email send-time optimization, modelled per person rather than per list.
- B2B email across many time zones and working patterns, where a single global send time is the wrong answer for most of the list.
Seventh Sense FAQ
How does Apple Mail Privacy Protection affect this product?
Potentially at the foundation, which is why the silence is notable. MPP prefetches images and registers an open whether or not a human looked. A model learning each person’s peak window from engagement data has to separate real opens from machine prefetches.
Is only supporting HubSpot and Marketo a weakness?
It is a deliberate trade and mostly a strength, since send time optimization needs deep access to contact-level history and the sending pipeline. The cost is concentration risk: migrate ESP and you lose the tool rather than reconfiguring it.
How large does my list need to be?
Larger than you might assume, and no minimum is published. A list of 25,000 emailed monthly gives each person twelve data points a year, which is thin. Ask what the model does for contacts with insufficient history.
