MailPeek MSG Viewer
MSG, EML, MBOX & winmail.dat
$3.99
Open Outlook MSG, EML, MBOX and winmail.dat / TNEF files on Mac, iPhone and iPad.
MailPeek makes Outlook message files easy to open and read without sending anything to the cloud. Open files, read messages, save attachments, and use headers or raw source only when you need more detail. Remote content is blocked by default, so emails cannot silently load external tracking resources unless you allow it.
Features:
• Open .msg, .eml, .mbox, .mht and .mhtml files
• Open winmail.dat / TNEF attachments and extract embedded files
• Read HTML, plain text and RTF message bodies
• Save attachments quickly
• Search by sender, recipient, subject and filename
• Native interface with Dark Mode and Quick Look support
• Block remote content by default to prevent external tracking
• View Email, Headers and Source in one app
• Export emails as PDF or share them directly
• Export contacts in multiple formats
• 100% local processing, nothing sent to the cloud
• One-time purchase for Mac, iPhone and iPad – no subscription
Built for everyday access to Outlook message files, with extra detail available when you need it.
