Asymmetric HubSpot Database: Segmentation & Cleanup
Overview
As part of Asymmetric's 2026 marketing engine launch, Mark Hope performed a comprehensive cleanup and segmentation of the HubSpot contact database. The result is a validated, enriched 37,000-contact database structured to support multi-channel outreach across nurture, ABM, and industry-specific campaigns.
HubSpot serves as the single source of truth for all contact activity, even when outreach is executed through external tools (SES for nurture, Orbit for ABM).

Cleanup Actions Performed
- Removed consumers — non-business contacts purged from the database
- Removed contacts without email addresses
- Validated all ~37,000 email addresses
- Enriched records — missing industry classifications and firmographic data were filled in programmatically via the HubSpot API (bulk operations, not manual UI clicks)
Segmentation Dimensions
1. Lead Quality Tiers
| Tier | Description |
|---|---|
| Tier 1 | High-quality leads — strong firmographic fit, known decision-maker, prior engagement |
| Tier 2 | Moderate quality — partial data, some engagement signals |
| Tier 3 | Low quality — minimal data, no engagement history |
Tier assignment uses an algorithm weighing contact completeness, engagement history, and fit against target criteria.
2. Industry Segments
The database is tagged by industry, including (but not limited to):
- Construction & Building
- Technology & Software
- Healthcare
- Food & Beverage
- Financial Services
- Manufacturing & Industrial
- Energy & Environment
Industry enrichment was required for a significant portion of contacts, as many records lacked this field prior to cleanup.
3. Ideal Customer Profile (ICP)
A dedicated ICP segment — "Mid-Market B2B" — identifies contacts meeting all of the following criteria:
- Revenue: $10M–$50M in annual sales
- Type: B2B company in a target industry
- Contact quality: Known decision-maker on record
Sub-segments within ICP:
- ICP with Significant Activity — multiple prior engagement touchpoints
- ICP with Some Activity — limited but present engagement history
Exclusion Logic
Contacts are excluded from general nurture and cold outreach campaigns under the following conditions:
| Condition | Excluded From |
|---|---|
| Marked as ABM target | All marketing campaigns |
| Has an active deal in pipeline | All marketing campaigns |
| Lifecycle stage = Customer | All marketing campaigns |
| In an industry-specific campaign (e.g., Food & Beverage, Energy & Environment) | General awareness/nurture funnel |
This ensures contacts receive only one coherent outreach track at a time and that active sales relationships are not disrupted by automated marketing.
HubSpot Operational Notes
Email Volume Constraint
HubSpot's free/starter tier limits direct email sends to 2,000 contacts. With 37,000 contacts in the database:
- Industry campaigns (typically <2,000 contacts per segment) can be sent directly from HubSpot
- Nurture campaigns (remaining ~35,000 contacts) are sent via AWS SES, with activity reported back to HubSpot
- ABM campaigns run via Orbit, also reporting back to HubSpot
API-Driven Management
Database operations (bulk updates, enrichment, segmentation) are performed via the HubSpot API rather than the UI, enabling faster and more reliable bulk changes.
Access
As of the March 2026 meeting, Melissa Cusumano was granted a dedicated HubSpot seat (reassigned from a former contact, Chris Ostergaard). Raphael holds a super admin / core seat. Karly Oykhman also has access.
