Campaign Monitor
Add Campaign Monitor to your product for your customers, and give your AI agents governed access to it.
Embed a Campaign Monitor integration so your customers can manage their own subscribers, lists, and campaigns from inside your product and get engagement events back as data your app can act on. A product event can add a subscriber to a list or start a send, so lifecycle messaging follows what a user actually did rather than a nightly export. Opens, clicks, bounces, and unsubscribes are delivered per tenant, and fastn handles each customer's credentials and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.

- 02Have each customer authenticate their Campaign Monitor account with OAuth or an API key.
- 03Map the lists, custom fields, and campaign templates your product uses, then enable actions and triggers.

Why teams use the Campaign Monitor integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Campaign Monitor integration without building it. Your customers connect their own Campaign Monitor 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 Campaign Monitor update is not your on-call problem.
- One integration serves your product and your agents. The same governed Campaign Monitor 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.

ClassyCampaign Monitor integration FAQ
How do I add a Campaign Monitor integration to my product?
Enable the Campaign Monitor connector in your fastn dashboard, then let each customer authenticate their own Campaign Monitor account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Campaign Monitor client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Campaign Monitor account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Campaign Monitor 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 Campaign Monitor 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 campaign engagement before recommending a follow-up send.
Who maintains the Campaign Monitor integration?
fastn does. When Campaign Monitor 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 Campaign Monitor 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 Campaign Monitor?
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 Campaign Monitor integration?
A common starting point: manage their own subscriber lists and segments from inside your product. 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 Campaign Monitor integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Campaign Monitor does not change your per-connector cost. You can start free with 3 connected accounts.
