How Mockmail Works
1. Create an inbox
Each inbox acts as its own virtual SMTP server with unique credentials.
2. Update your app's SMTP settings
Each inbox comes with unique SMTP credentials. Simply enter these credentials into your application to start capturing outgoing emails.
3. Send emails like normal
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.
4. Inspect everything
Preview HTML, plain text, headers, and attachments right in your browser. Share a link with your team, no setup, no mail delivery, no risk.
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 mail server credentials. Simply use these details in your application, and all emails sent through this SMTP, no matter the "To Adress", will 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.
Dedicated test email addresses
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 email 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.
