FreshMail
Add FreshMail to your product for your customers, and give your AI agents governed access to it.
Embed a FreshMail integration so your customers can run email campaigns to their own subscriber lists from events inside your product, instead of exporting a CSV every week. Engagement comes back as a high-volume event stream, so ordering and deduplication are handled for you and a retry does not send the same message twice. fastn handles per-customer credentials and API upkeep.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers add or update subscribers on their own lists from activity in your product.
Start a campaign or send a message when something happens in your product rather than on a schedule.
Read list membership so your product shows who is already being messaged.
Trigger your product on engagement events such as opens, clicks, bounces, and unsubscribes.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent checks whether a contact is already subscribed before recommending an outreach step.
An agent adds a subscriber to a list or queues a send within governed permissions.
An agent reacts to an unsubscribe or bounce and updates the customer record in your product.
Example prompt
Show subscribers added this month who have not opened a single message, grouped by list.
Set up FreshMail in 4 steps
- 01Open the FreshMail connector from your fastn dashboard.
- 02Have each customer supply their own FreshMail API credentials.
- 03Map the lists and subscriber fields 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 FreshMail integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a FreshMail integration without building it. Your customers connect their own FreshMail 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 FreshMail update is not your on-call problem.
- One integration serves your product and your agents. The same governed FreshMail 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.

Zoho CRMFreshMail integration FAQ
How do I add a FreshMail integration to my product?
Enable the FreshMail connector in your fastn dashboard, then let each customer authenticate their own FreshMail account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no FreshMail client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own FreshMail account?
Yes. Every connection is scoped to the individual customer, so each authorises their own FreshMail 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 FreshMail 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 checks whether a contact is already subscribed before recommending an outreach step.
Who maintains the FreshMail integration?
fastn does. When FreshMail 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 FreshMail 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 FreshMail?
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 FreshMail integration?
A common starting point: add or update subscribers on their own lists from activity in 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 FreshMail integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding FreshMail does not change your per-connector cost. You can start free with 3 connected accounts.
