SendTrace is an automated email testing tool designed for developers and QA teams who need to inspect notification emails before they reach real users. It lets you see the full content, variables, formatting, and timing of outgoing emails โ without sending anything to real inboxes.
Built by a senior engineer, SendTrace focuses on simplicity and developer-friendly workflows. No complex setup, no risky exposure of real mailboxes, and no credit drain from unwanted messages.
With SendTrace, you can:
Test automated emails instantly via a simple API
Inspect variables, HTML, formatting, and payloads
Capture only the messages generated during your test session
Keep your own inbox clean and safe
Avoid overpaying via โper-emailโ billing models
SendTrace is lightweight, reliable, and ideal for indie developers, QA testers, and small teams who want a clean and accessible way to debug email workflows.
A practical, minimal, and cost-effective alternative to email testing tools like Mailtrap, Mailosaur, and Testmail.
