Overview
MNTN’s HubSpot integration lets you connect your HubSpot contact lists to MNTN and use them in two ways:
Sync HubSpot lists into MNTN for audience targeting and exclusions.
Use your HubSpot contact lists as CRM audiences in MNTN campaigns without manual uploads.Send MNTN ad exposure data back to HubSpot for attribution.
When HubSpot attribution is enabled for a synced list, MNTN matches existing HubSpot contacts to MNTN ad impressions and sends impression details back to HubSpot as notes on the contact record.
This helps you activate HubSpot audiences in MNTN and understand how MNTN ad exposure supports downstream lead and sales activity in HubSpot.
Shared data
The HubSpot integration supports two data flows:
HubSpot Lists to MNTN
MNTN syncs your HubSpot contact lists into MNTN automatically. Once synced, these lists populate as CRM audiences that can be used for campaign targeting or exclusion.

MNTN Impression Data to HubSpot
Only lists with HubSpot Attribution enabled send MNTN ad impression data back to HubSpot, where it’s matched to your contacts. This lets you see which leads were influenced by MNTN directly in HubSpot.
