How much does Seventh Sense cost?

Business pricing starts at $400/month for 25,000 HubSpot contacts, scaling in 5,000-contact increments. Marketo pricing is custom, typically starting around 150K contacts. There are no per-seat fees, and onboarding is bundled.

Which email platforms does it integrate with?

Seventh Sense only works with HubSpot and Marketo. It does not support Mailchimp, Klaviyo, Customer.io, or other ESPs. If you use a platform outside these two, the tool will not function.

Is it suitable for small email lists?

It is best for high-volume B2B lists. The vendor suggests skipping it if your list is under ~10K active contacts. Value scales with recipient engagement variance, so small, homogeneous audiences see less lift.

Does it offer a free trial?

Yes, a free trial is available with no credit card required. The vendor also claims SOC 2 Type II, GDPR, and CCPA compliance for data security and privacy.

How does it handle disengaged contacts?

Audience Recycling automatically suppresses disengaged contacts to protect sender reputation. It reactivates them when their probability of opening recovers, helping maintain deliverability over time without manual list cleaning.

In short

Seventh Sense optimizes email send times and frequency for HubSpot and Marketo users. It uses AI to stagger delivery and suppress disengaged contacts to protect deliverability.

Best for

Pick Seventh Sense if you run high-volume lifecycle email out of HubSpot or Marketo and deliverability or list fatigue is hurting pipeline.

Skip if

Skip it if you send from Mailchimp, Klaviyo, Customer.io, or any ESP outside HubSpot/Marketo, or if your list is under ~10K active contacts.

Seventh Sense is a marketing-ops add-on that bolts AI deliverability tooling onto HubSpot and Marketo. Instead of generic 'best time to send' guesses, it builds a per-recipient engagement model and staggers email delivery to each contact's individual peak window, then layers in frequency caps, blackout windows, and priority lanes to keep campaigns from cannibalizing each other. Audience Recycling auto-suppresses disengaged contacts and reactivates them when their probability of opening recovers, which is meant to protect sender reputation over time.

This is squarely a B2B revenue-team product, not a consumer tool. Pricing starts at $400/month for 25,000 HubSpot contacts and scales in 5,000-contact increments; Marketo is custom and kicks in around 150K contacts. There are no per-seat fees and onboarding/support are bundled, which is unusual at this tier. The vendor claims SOC 2 Type II, GDPR, and CCPA compliance, plus a free trial with no card.

It only matters if you are already running serious volume in HubSpot or Marketo. Outside those two ESPs it does nothing, and the value scales with how much your engagement actually varies by recipient, so small lists with homogeneous audiences will see less lift than enterprise databases.

Editor's take

A focused, unsexy point solution that does one thing well: squeezing more opens out of HubSpot and Marketo by sending to each contact at their own peak window. The platform lock-in is the catch, but if you live inside those two ESPs the ROI math is usually straightforward.
