eml.ninja

Open and verify .eml attachments from Gmail and Outlook Web.

eml.ninja helps you open and inspect .eml email files directly from supported webmail workflows. Main features: # Detects received .eml attachments from supported webmail pages # Opens supported attachments directly in eml.ninja # Lets you upload .eml files manually when direct access is unavailable # Works with the eml.ninja app to inspect message content and headers # Supports Gmail directly and provides fallback handling for other providers such as Outlook # The add-on is designed to make .eml analysis faster and more convenient without requiring users to manually locate and manage files in most supported cases. It does not inject editing controls into email providers. Instead, it uses a lightweight popup to list available .eml attachments on the current page and send them to eml.ninja for viewing and verification.
