Marketing Hub ↔ SalesforceSalesforce Sales Cloud
The integration we are called in to fix most often. The native connector is almost never the fault — the failure is a data-model mismatch in lifecycle stages, ownership and campaign logic that was never designed consistently across the two platforms.
To Salesforce: qualified contacts, lifecycle stage, campaign membership, engagement history. To HubSpot: opportunity stage, closed-won and closed-lost outcomes, account owner.
Marketing Hub ↔ Sales HubHubSpot Sales Hub
Where both hubs sit in the same portal the integration is native, but the handoff still has to be designed: which score triggers a task, which owner receives it, and what a rep sees on the record when they open it.
To Sales Hub: lead score, lifecycle transition, nurture history. To Marketing Hub: deal stage, sequence enrolment, meeting outcomes.
Marketing Hub → Ad PlatformsGoogle, LinkedIn & Meta Ads
Connecting the ad accounts is a five-minute job; making spend legible against closed revenue is not. The value sits in the campaign taxonomy and the audience sync design behind the connection.
To the ad platforms: suppression and lookalike audiences, offline conversion events. To HubSpot: spend, impressions and click data joined to the contact record.
Marketing Hub → AnalyticsGoogle Analytics 4 & Looker Studio
HubSpot reporting answers marketing's questions; the warehouse and BI layer answers finance's. Both need to agree on what a session, a source and a conversion mean before either is trusted.
To analytics: conversion events, campaign parameters, form submissions. To reporting: pipeline and revenue joined back onto the acquisition source.
Marketing Hub ↔ AutomationZapier, Workato, Celigo & n8n
Middleware is the right answer for a long tail of low-volume connections and the wrong answer for anything that carries revenue-critical data at scale. We say which is which before it becomes a support problem.
Into HubSpot: enrichment, product usage signals, third-party form data. Out of HubSpot: notifications, ticket creation, downstream record updates.
Marketing Hub → Sales EngagementSlack, Outreach & Salesloft
The last hundred metres of the handoff. A high-intent lead is worth far less if the alert lands in a channel nobody watches, or the sequence enrolment has to be done by hand.
To the sales stack: scored lead alerts, sequence enrolment, routing decisions. Back to HubSpot: activity logging and reply outcomes on the contact timeline.
