Rate the app

If the app did the job, a rating helps other people find it: rate EML & MSG Viewer on the App Store. If something did not work, email support first so it can be fixed.

Remote images

Remote Content can be turned off in the app for local-only viewing and PDF export.

Privacy requests

The app does not create accounts or store user data on developer-operated servers. For privacy questions, email support or review the privacy policy.

Troubleshooting

The file will not open.

Confirm the file extension is .eml or .msg. Some Outlook items are calendar, contact, task, encrypted, or protected files rather than normal email messages. Step-by-step guides: .eml, .msg, winmail.dat.

An attachment will not preview.

Attachment preview depends on iOS Quick Look support for that file type. You can still try sharing or saving the attachment.

An email looks different from the original.

HTML emails can depend on remote images, fonts, and external resources. Use Remote Content settings to choose between fidelity and local-only rendering.

I need a PDF for records.

Open the email, choose PDF export, and include metadata and attachment inventory when those details are needed for documentation.
