eml.ninja 作者: FastFlowUp

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.
