This article documents the technical architecture used to run automated ABM email sequences for [1] — and potentially other clients — where HubSpot's native sending capabilities are insufficient or unavailable at the client's subscription tier. The pattern decouples email sending from HubSpot while keeping engagement data visible inside the CRM.
First deployed February 23, 2026. Discussed in [2].
HubSpot's native email sending has two common constraints:
This pattern routes email delivery through AWS SES while keeping HubSpot as the CRM of record for engagement data.
Orbit (playbook + scheduling)
↓
Automation server (polls every ~1 min)
↓
AWS SES (sends email)
↓
AWS tracking tools (open/click monitoring)
↓
Webhook → HubSpot (logs engagement as "logged email" activity)
| Component | Role |
|---|---|
| Orbit | Manages the ABM playbook, target list, contact status, and send schedule |
| Automation server | Polls for pending sends; orchestrates the flow between Orbit, SES, and HubSpot |
| AWS SES | Delivers the actual email; bypasses HubSpot sending limits entirely |
| AWS tracking tools | Monitors opens and clicks at the infrastructure level |
| HubSpot webhooks | Receive engagement events from AWS and log them as activity on the contact/company record |
Orbit provides a unified view across all client ABM campaigns without requiring the operator to log into each client's HubSpot account. Key views available in Orbit:
Clients who want visibility can be given access to Orbit directly, though HubSpot remains the CRM of record.
| Metric | Result |
|---|---|
| Emails sent | 100 |
| Open rate | 13% |
| Click rate | 11% |
| Bounce rate | 3% |
| Unsubscribes | 3 |
Context: Industry benchmarks for cold B2B outbound typically run 20–30% open rate and 2–5% click rate. An 11% click rate on the first send of a cold sequence is notably strong and suggests good list quality and relevant messaging.
This pattern was also being evaluated for [3], which does not have a HubSpot subscription tier that supports native email automations. The same Orbit + SES + webhook stack can be connected to any client's HubSpot account.
When deciding whether to use this pattern vs. native HubSpot sending, consider:
