Benchmark Email
Add Benchmark Email to your product for your customers, and give your AI agents governed access to it.
Benchmark Email's current REST API is served from clientapi.benchmarkemail.com and replaced an older XML-based interface, so a lot of third-party code and blog examples still on the web target endpoints that no longer exist. The core objects are contact lists, the contacts inside them, emails (the campaigns), signup forms and the reporting resources for opens, clicks and bounces. Contacts are stored per list rather than in one global address book, so the same address subscribed to two lists is two records with independent custom fields and status, and deduplication is your job. Adding contacts is done as a bulk operation against a named list, and it is accepted asynchronously, so a successful response does not mean the addresses are queryable yet. Campaign reporting is only available once an email has actually been sent, and drafts return empty report structures rather than an error. fastn keeps each customer's token, handles the list-scoped contact model and maintains the connection as credentials change.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let a customer connect their own Benchmark Email account so your app can add subscribers to their chosen list
Sync opt-in status back from Benchmark Email so unsubscribes are respected in your own database
Show a customer their campaign open and click figures inside your product instead of sending them elsewhere
Create a list per customer segment automatically when a new segment is defined in your app
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
Ask an agent which lists a given email address appears on for one tenant, and with what status
Have an agent summarise the last campaign's opens, clicks and bounces for a customer
Let an agent add a batch of subscribers to a named list, with the write audited per tenant
Example prompt
How did last week's newsletter perform, and how many people unsubscribed from it?
Set up Benchmark Email in 4 steps
- 01Enable the Benchmark Email connector from your fastn dashboard.
- 02Have each customer authorise their own Benchmark Email account, so calls run under their credentials rather than a shared key.
- 03Decide which campaigns, segments and subscribers your product needs, map those fields, then enable the actions and triggers you want.
- 04Call it from your product and expose it to your agents through the same governed connection.
Why teams use the Benchmark Email integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Benchmark Email integration without building it. Your customers connect their own Benchmark Email 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 Benchmark Email update is not your on-call problem.
- One integration serves your product and your agents. The same governed Benchmark Email 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.

Benchmark Email integration FAQ
How do I add a Benchmark Email integration to my product?
Enable the Benchmark Email connector in your fastn dashboard, then let each customer authenticate their own Benchmark Email account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Benchmark Email client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Benchmark Email account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Benchmark Email 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 Benchmark Email integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. Ask an agent which lists a given email address appears on for one tenant, and with what status
Who maintains the Benchmark Email integration?
fastn does. When Benchmark Email 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 Benchmark Email 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 Benchmark Email?
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 Benchmark Email integration?
A common starting point: let a customer connect their own Benchmark Email account so your app can add subscribers to their chosen list. 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 Benchmark Email integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Benchmark Email does not change your per-connector cost. You can start free with 3 connected accounts.
