How to save an email as a .eml file

Best done on a desktop computer. Most mobile mail apps can’t export a .eml file.

GmailOpen the email, click the ⋮ menu (top right), then Download message.

OutlookOpen the email, then File → Save As and choose the .eml format.

Apple MailSelect the email, then File → Save As and set the format to Raw Message Source.

Alternative submission methods

Prefer not to upload through the UI? You can also submit suspicious emails through one of the channels below.

Forward as attachment

Forward any suspicious email as an .eml attachment to our analysis mailbox. Static malware analysis is automatically run on attachments submitted this way. The forwarding mailbox requires a Seat License; on the Free Tier, upload the .eml here instead.

Outlook note: Outlook rewrites portions of the original message headers when using Forward as Attachment, which can affect SPF, DKIM, and DMARC results in the report. For the most accurate header authentication results, save the original message as a .eml file and upload it through the UI or API instead.
