Salesforce Marketing Cloud
Add Salesforce Marketing Cloud to your product for your customers, and give your AI agents governed access to it.
Embed a Salesforce Marketing Cloud integration so your customers can drive journeys, subscriber lists, and campaign activity from inside your product, and so your agents get governed access to the same data. fastn manages each customer's business unit scoping, OAuth, and API maintenance, so one integration serves every customer's Marketing Cloud setup.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers sync subscribers and data extensions into your product, mapped to their own attributes.
Trigger a journey entry from an event that happens in your product.
Read email, click, and bounce activity so your product can act on real engagement.
Support each customer's own business units with per-tenant OAuth and scoping.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reads recent campaign engagement before drafting a follow-up.
An agent adds a contact to a journey, within governed permissions.
An agent reacts to a bounce or unsubscribe event and updates the downstream record.
Example prompt
Find contacts who opened the onboarding email twice but never clicked, and add them to the re-engagement journey.
Set up Salesforce Marketing Cloud in 4 steps
- 01Open the Salesforce Marketing Cloud connector from your fastn dashboard.
- 02Have each customer authenticate their Marketing Cloud tenant and select the business units to expose.
- 03Map the subscriber attributes, data extensions, and journeys your product uses, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Salesforce Marketing Cloud integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Salesforce Marketing Cloud integration without building it. Your customers connect their own Salesforce Marketing Cloud account inside your product and work their campaigns, segments and subscribers there, with no per-customer code on your side.
- Handle the part that actually costs time: engagement data arrives as a high-volume event stream, so ordering and deduplication matter. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Salesforce Marketing Cloud update is not your on-call problem.
- One integration serves your product and your agents. The same governed Salesforce Marketing Cloud connection powers in-product features and gives AI agents scoped, audited access, so you trigger and measure campaigns from inside your product without wiring it twice.

ClassySalesforce Marketing Cloud integration FAQ
How do I add a Salesforce Marketing Cloud integration to my product?
Enable the Salesforce Marketing Cloud connector in your fastn dashboard, then let each customer authenticate their own Salesforce Marketing Cloud account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Salesforce Marketing Cloud client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Salesforce Marketing Cloud account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Salesforce Marketing Cloud account and only ever sees their own campaigns, segments and subscribers. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Salesforce Marketing Cloud integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent reads recent campaign engagement before drafting a follow-up.
Who maintains the Salesforce Marketing Cloud integration?
fastn does. When Salesforce Marketing Cloud changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Can I trigger a Salesforce Marketing Cloud campaign from an event in my product?
Yes. Product events can start a campaign, add a contact to a segment, or enrol someone in a journey, so lifecycle messaging follows what a user actually did rather than a nightly export.
Can I read engagement results back from Salesforce Marketing Cloud?
Yes. Results come back scoped per tenant, so your product can act on them without one customer's data mixing with another's. What you get depends on the channel: opens, clicks, bounces and unsubscribes where there are sends, and impressions, spend and conversions where there are campaigns.
What can I build with the Salesforce Marketing Cloud integration?
A common starting point: sync subscribers and data extensions into your product, mapped to their own attributes. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Salesforce Marketing Cloud integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Salesforce Marketing Cloud does not change your per-connector cost. You can start free with 3 connected accounts.
