Multi-project by default

Easy for developers. Clear for agents.

MCP and OpenAPI help coding tools understand the surface. The Node SDK, REST API, and SMTP keep the finished integration ordinary and portable.

Send with the typed Node.js SDK, a direct REST request, or the SMTP settings your app already understands. The same logs and delivery controls sit behind each path.

Simple where it should be. Visible where it matters.

Build, test, and operate email without stitching together a different tool for every stage.

Test the unhappy paths safely.

Simulate delivery, bounce, complaint, and suppression results before a customer is ever involved.

Open the simulator guide

Follow each recipient outcome.

See the request, message, and delivery timeline together so a support question has a concrete answer.

See delivery events

Keep every app in its own lane.

Separate projects, keys, domains, and logs while managing them from one account.

See project controls

One quiet place to run the work.

Projects keep each product’s identity and activity separate. Delivery logs show what happened. Suppressions help stop repeat sends before they leave.

Need a detail we missed? Talk with us.

Can I test without sending real email?

Yes. Use the sandbox sender and simulator recipients to test delivered, bounced, complained, and suppressed outcomes without contacting a real inbox.

Do transactional and marketing email live together?

Yes. Free, Pro, and Scale include both paths in one workspace, one package, and one subscription.

Can I keep using SMTP?

Yes. Point a compatible app at smtp.noticeapi.com on port 465 with implicit TLS and an API key as the password.

How does the free plan work?

Start with one project, one sending domain, 3,000 transactional emails, and sandbox testing each month. Add a card to activate production sending; Free itself stays at $0.

Email infrastructure that stays understandable.

Start with one project, one API key, and a sandbox send.
