Sync HubSpot Lists to MNTN

Sync HubSpot contact lists into MNTN so you can use them as CRM audiences for targeting and exclusions.

Overview

MNTN’s HubSpot integration lets you sync HubSpot contact lists into MNTN automatically. Once synced, these lists populate as CRM audiences in MNTN, where you can use them for targeting or exclusions in your audience strategy.

Syncing HubSpot lists is also the first step required for HubSpot attribution. After a list is synced, you can enable HubSpot attribution to send MNTN ad exposure data back to HubSpot for matched contacts.

Use this article to connect HubSpot, sync HubSpot contact lists to MNTN, manage synced lists, or disconnect the integration.
