Email Preview Testing

Helps users test how their emails will look across different devices, screen sizes, and email clients (like Gmail, Outlook, Yahoo) before sending, preventing broken layouts and improving deliverability/readability.

User installs extension -> Logs into Inbox Pirates account -> Navigates to supported email provider (e.g., Gmail) -> Clicks extension button or context menu -> Extension sends email content to Inbox Pirates backend -> Backend generates preview images -> User views previews in extension popup or redirected website.

Target users: Email marketers / Developers / Business owners sending newsletters

The extension relies heavily on the external Inbox Pirates service for the actual preview generation. The local code primarily handles UI and API communication. Paid features are tied to the service subscription rather than a one-time purchase within the extension.
