Quickstart

Send any email to ... — the part before the @ can be anything (... accepts it all), so you can tag different test runs however you like. Then press "Check now" and it'll show up right here in the Mail viewer below, no page reload needed.

Next: read the documentation to learn about pulling mail programmatically, spam scoring, webhooks, and more — or try the GraphQL Playground if you're familiar with GraphQL.

Namespaces

Every address you receive mail on looks like namespace.anything@quickinbox.net. Create more namespaces if you need to keep traffic separated.

API keys

Use an API key to create namespaces and read mail programmatically — same endpoints the dashboard uses, no extra setup.

Custom Domains

Receive test mail on mail.yourcompany.com instead of a quickinbox.net address. Your first custom domain is free on every plan, including Free. Each additional domain is a $5/mo add-on.

You haven't added a custom domain yet.

SMS Testing Add-on

Rent a real phone number and receive SMS / OTP codes programmatically — same idea as a QuickInbox address. Completely optional, separate from your base plan.
