Capture outbound email in Mailtrap Email Sandbox for development, staging, CI, HTML inspection, spam checks, and fake inbox tests.

When to use

• You want **no real delivery**: dev, staging, CI, or demos where mail must stay in a **test inbox**.
• You need to **inspect** what was sent: bodies, headers, attachments, or basic checks (e.g. spam report) via **Sandbox / Testing API** or the **UI**.
• You are **automating** tests against captured mail.
• You will **only change SMTP settings** so an existing app sends into a sandbox—no need for a framework-by-framework tutorial from this skill.

When not to use

• **Live** sends to real recipients (`mailtrap-sending-emails`).
• For full framework setup guides or detailed API references, link users to Mailtrap's Integration tab for SMTP/API details and the [API docs](https://docs.mailtrap.io/developers/) for specifics—don't cover every framework or API field here.
• This skill covers sandbox usage patterns; use Mailtrap's current API docs for full endpoint schemas.
