About:
MailCatcher runs a simple SMTP server along with a web interface that captures and displays emails as they arrive. It provides a non-destructive way to test email functionality in applications without sending real emails to actual recipients. This tool is invaluable for development and debugging of email workflows.

Key Features:

SMTP server with web UI
Instant email preview
Supports HTML and attachments
Zero configuration required

Use Cases:

Testing email functionality in web applications
Debugging email templates and formatting
Validating email delivery in development environments

Alternatives:

MailHog – Similar functionality with more advanced features like API access and webhook support
FakeSMTP – Java-based GUI tool, simpler but lacks web interface for viewing emails
