What is a Unified Email API?
Email platforms each store data differently, with their own authentication and schemas. A Unified Email API standardizes these into one interface — operations like Create Ticket, Get Ticket By Id, Get Contacts work the same way no matter which platform is on the other end, while Knit manages translation, rate limiting, retries, and sync management underneath.

Unified Email API vs. building it yourself
Building it yourself
- A separate integration for every Email platform you support
- Different schema, auth, and pagination per platform
- You build and maintain OAuth for each platform
- Poll each API on your own schedule
- Engineering effort grows with every new platform
- Weeks to months per platform, per engineer
With Knit
- One Unified Email API covers every platform you support
- One normalized schema across every platform
- Embedded Auth handles OAuth, storage, and refresh for you
- Extensive webhook support for real-time sync
- Describe a missing app to the Integrations Agent and get it built instantly
- Live in days, not months

Easy to integrate. Knit's dashboard is intuitive for setting up and testing integrations, and the sandbox is extremely useful during development.

Knit shipped a brand-new Timesheet API in a week and handed us a ready-to-use NetSuite sandbox. That velocity is priceless when you're running payroll in 40+ countries.

FAQ
Common questions about the Unified Email API
Which Email systems does Knit support?
2 Email platforms today — including Gmail, Outlook and more. Missing one you need? Knit's AI-assisted connector-build process typically adds a new one within days.
Does the Unified Email API support both reading and writing data?
Yes. It supports both reads and writes, so you can build bi-directional sync use cases — not just pull Email data, but push updates back to the source app.
How does authentication work across Email platforms?
Knit provides an embedded Auth component (white-labeling available on higher tiers) that handles OAuth, credential storage, and refresh — your customers authorize once through Knit, and you never touch raw credentials.
What is the timeline for adding a missing Email connector?
Typically days, not months — the same AI-based connector-build tooling that lets us maintain the 2 Email connectors already live.
Do you store Email data or customer PII?
No. Knit acts as a stateless passthrough — data is processed on our application server and sent directly to your webhooks, without being stored on Knit's servers.
What is the pricing model, and is there a free trial?
You choose the model that fits your business — pricing based on integrated accounts, or based on API call volume. Every plan includes a 30-day free trial before billing starts.
