Marketing Automation integrations

Your customers connect their own account, and your product reads and writes their campaigns, segments, subscribers through one governed connection. Trigger and measure campaigns from inside your product.

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 across every connector in this category, so that work does not land in your backlog.

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.

Start with whichever your customers already run, not with the largest vendor. All 98 connectors here share one interface in your product, so adding a second is configuration rather than another integration project, and the order you add them in does not lock anything in.

Yes. Every connector here is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited, so an agent reaches exactly what that customer authorised and nothing else.
