    • Email: test@inzen.email
    • Password: Test6475

2. Send a Test Email:
From your personal email client (like Gmail, Outlook, etc.), compose a new email and send it directly to our project's central Postmark inbound address:

0ae9c2de491edfecc2fc0383e46b642a@inbound.postmarkapp.com
Enter fullscreen mode Exit fullscreen mode

3. See the Magic!
Within seconds, return to the Inbox Zen dashboard. You should see your email appear in the list, automatically analyzed by the AI, and the created tasks.
