Gmail
Add Gmail to your product for your customers, and give your AI agents governed access to it.
Embed a Gmail integration in your product so your customers connect their own inbox and your AI agents get governed access to it. fastn handles per-tenant OAuth, the connector upkeep, and observability, so you ship Gmail as a product feature instead of building and maintaining an email integration yourself.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own Gmail so your product sends email from their address, with no shared inbox or SMTP for you to run.
Sync incoming email into your app's CRM, support queue, or activity timeline automatically.
Trigger your product's workflows the moment a customer receives an email that matches a rule.
Give every customer isolated, revocable Gmail access with per-tenant OAuth.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An AI agent searches the user's inbox and summarizes the latest thread before it acts.
An agent drafts and sends replies from the user's own Gmail, within the permissions you grant.
An agent watches for new mail and kicks off a workflow in real time.
Example prompt
Find unread emails from my manager this week, summarize what each is asking for, and draft a reply to the most urgent one.
Set up Gmail in 4 steps
- 01Open the Gmail connector from your fastn dashboard.
- 02Have each customer authenticate their Gmail with OAuth (per tenant, no shared credentials).
- 03Enable the actions and triggers your product needs.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Gmail integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Gmail integration without building it. Your customers connect their own Gmail account inside your product and work their messages, conversations and participants there, with no per-customer code on your side.
- Handle the part that actually costs time: anything sent is user-visible, so duplicates and misfires are immediately embarrassing. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Gmail update is not your on-call problem.
- One integration serves your product and your agents. The same governed Gmail connection powers in-product features and gives AI agents scoped, audited access, so you put the right message in front of the right team automatically without wiring it twice.

GongGmail integration FAQ
How do I add a Gmail integration to my product?
Enable the Gmail connector in your fastn dashboard, then let each customer authenticate their own Gmail account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Gmail client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Gmail account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Gmail account and only ever sees their own messages, conversations and participants. 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 Gmail 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 AI agent searches the user's inbox and summarizes the latest thread before it acts.
Who maintains the Gmail integration?
fastn does. When Gmail 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.
Does each customer connect their own Gmail account?
Yes. Every customer authorises their own Gmail account, so messages, meetings and notifications originate from their workspace under their permissions. You never proxy through a shared account, which also means a customer revoking access affects only their own connection.
How are duplicate notifications avoided?
Sends are deduplicated per event, so a retry after a network failure does not post the same message twice into a channel people are reading.
What can I build with the Gmail integration?
A common starting point: let each customer connect their own Gmail so your product sends email from their address, with no shared inbox or SMTP for you to run. 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 Gmail integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Gmail does not change your per-connector cost. You can start free with 3 connected accounts.
