How Mockmail Works
Create Your Inbox
Your Mockmail Inbox is your virtual SMTP server that allows you to easily debug your application's emails. All e-mails sent via this inbox will end up in this inbox according to the "catch-all" principle.
Configure SMTP Credentials
Each inbox comes with unique SMTP credentials. Simply enter these credentials into your application to start capturing outgoing emails.
Send & Debug Emails
Send emails from your application as usual. Every email is stored in your Mockmail inbox, where you can conveniently review and debug them via a user-friendly web interface.

Prevent Test Emails from Reaching Real Customers
With Mockmail, test emails stay where they belong—away from customer inboxes. Each test inbox comes with its own dedicated SMTP server and unique login credentials. Simply use these details in your application, and no matter who the emails are addressed to, they will all be captured in your test inbox. This ensures a controlled testing environment where you can easily review and debug your emails without any risk.
Access shared inboxes together
Work as a team with Mockmail's shared test inboxes. Easily invite your colleagues and manage access with a flexible permission system. Control who can view and use each inbox—for example, grant your QA team access to the test environment's inbox while keeping other inboxes private. Effortless collaboration, seamless email debugging.


Send Emails Directly to Your Inbox
Each Mockmail inbox comes with a unique email address, allowing you to receive emails directly without needing to configure an SMTP sender. Simply send an email to your inbox assigned address, and it will appear in your Mockmail inbox for easy debugging and review.
Forward Emails automatically to a Webhook
Streamline your email workflow with webhook forwarding. Configure your inbox to automatically forward incoming emails to a webhook URL of your choice, enabling real-time processing, automation, and seamless integration with your applications.
