Inspect what your app sent
Open an inbox and select a captured message. The inspector separates the useful views so you can diagnose content and delivery data quickly.
Rendered, sanitised HTML for a visual check.
The exact body variants your mailer generated.
From, To, Cc, Reply-To, Message-ID and custom headers.
The original raw MIME message for low-level debugging.
Extracted URLs for verification and reset-flow checks.
Names, types and downloadable captured files.
Deleting a message removes it immediately. Clearing an inbox removes every captured message in it. Otherwise messages expire automatically after the plan's retention period.
