See the workflow, step by step
  1. Create a dedicated test inbox.
  2. Start a wait, then trigger your application’s email.
  3. Read the message and assert the expected content.

Retrieve plain-text content, headers and original MIME messages. Your tests decide which codes or links to use.

Test signup emails from form submission to verified account

A successful send request is only the beginning. A useful email test checks that the right message arrives, that its code or link belongs to the test account, and that completing the action changes the application state.

Check delivery separately

Use the dashboard to send to a mailbox you control and inspect Logs. Remote-server acceptance does not prove inbox placement: check the actual mailbox and spam folder. This is a different test from validating your app’s signup flow.

Automate your app’s email flow

Use a unique temporary inbox per parallel test. Your application sends through its existing provider. Start the API wait before submitting the form, then check the matched code and the resulting account state. No change of sending provider is required.

Know what the test proves

An inbox test proves arrival and content for that route. It does not prove deliverability to every provider. Your app must enforce token expiry and single use. Incoming usage, storage and retention limits still apply.

Build the first working flow

  1. Create a temporary inbox for one signup attempt.
  2. Start the wait before your application sends the verification email.
  3. Submit your signup form using the temporary address.
  4. Use the matched code and assert that the account is verified.

Frequently asked questions

Do I have to connect or replace my email provider?

No. Use the test address in your app. Your current provider sends the message to InboxIt just like any other recipient. Your test runner uses the InboxIt API to read the result.

What can I try for free?

The Free plan includes 1,000 outbound emails and a separate allowance of 1,000 incoming emails per calendar month. Daily sending, storage and retention limits apply. Review the current plan limits before running a large test suite or integration.
