How do I test emails in CI/CD?

Use Inboxical's REST API or SDKs. Set your API key as an environment variable, create inboxes in your test setup, trigger email flows, then assert delivery — works in GitHub Actions, GitLab CI, CircleCI, and any CI/CD platform.

Do I need to run an SMTP server in CI/CD to test emails?

No. Inboxical is a cloud API — no SMTP server, no Docker containers, no infrastructure to manage. Just an API key and your test framework.

How reliable is email testing in CI/CD with Inboxical?

Inboxical uses long-polling to wait for emails instead of arbitrary delays. Combined with isolated inboxes per test, this eliminates flaky tests from shared state or timing issues.

Use Case

CI/CD email verification
that actually works.

Email is critical infrastructure. Test it like you test everything else — in your pipeline. Inboxical gives you isolated inboxes, reliable delivery assertions, and zero infrastructure to manage.

Inboxical integrates with any CI/CD platform that can make HTTP requests.

GitHub Actions

Set INBOXICAL_API_KEY as a repository secret. Works with any test runner.

GitLab CI

Add the API key as a CI variable. Run email tests in any stage.

CircleCI

Store the key in project settings. Email tests run alongside your existing suite.

Any CI

REST API works from any environment. curl, Node.js, Python — whatever your pipeline uses.
