Two atomic utilities we built for HubSpot users.
A deliverability audit and a split-test workflow action. Free to install, no card required. Each tool answers one specific question — and works well in isolation.
If you want the full picture — every send optimized per person, audience recycling, reputation monitoring, cross-program orchestration — try the platform instead. Same effort. More leverage.
Deliverability audit
Slice your HubSpot email reporting by inbox provider — Gmail, Outlook, Yahoo, Verizon Media, and the long tail of business domains. See which provider is dragging your engagement down.
- Per-provider open/click rate segmentation
- Separates B2C providers from business mail
- Segments Google Workspace vs. Microsoft 365 performance
- Free to install — but setup is a real project
Split test automation
Native HubSpot workflow action. Run real A/B/C/D/E tests (up to 5 variations) inside any workflow — no spreadsheets, no manual list randomization, no rebuild between tests.
- 2-, 3-, or 5-cohort split actions inside workflows
- Test content, send time, paths, frequency — anything
- Run as long as you want, then pick the winner
- Free, installed via HubSpot Marketplace
These tools answer one question each. Useful, free, and installable in 2 minutes — but the real lift comes from the full platform: per-person send-time AI, audience recycling, deliverability monitoring across providers, and cross-program orchestration. That's where customers see +44% engaged audience and +11% revenue lift, year one.
So we'd rather you start with the trial. Same effort to install. Dramatically more upside.
