Bulletproof Your Emails

Capture, inspect, and debug transactional emails without spamming real inboxes.

Transactional Email Sandbox

Test your registration, password reset, and notification emails in a controlled environment. FileFusion Mail Sandbox captures your outbound JSON payloads and renders them exactly as your users see them.

How it works

1. Copy your unique sandbox URL.
2. Configure your app to send transactional mail via JSON POST.
3. Inspect the rendered HTML, attachments, and metadata here.

Private: Your sandbox is uniquely identified by your Developer ID.

🚀 Advanced Testing

Perfect your transactional flow:

HTML Preview: Toggle between Desktop & Mobile views.
Metadata: Inspect raw headers and MIME structures.
Payloads: Test with dynamic JSON templates.
