How to Save Multiple Emails to a Single File in Mac OS X Mail

In macOS 10.13 and later, this article describes how to save Apple Mail emails to a single text file.

Save Multiple Emails in a Single File

To save multiple messages from Mail to a single consolidated text file:

1. Navigate to the folder that contains the messages you wish to save.
2. Select the emails you wish to save to a single file by highlighting them.

• While holding Shift, click a contiguous region.
• While holding down Command, select multiple emails.
• Additionally, you can combine these two methods.

3. From the menu, choose File > Save As.
4. Under Save As, type a file name that is different from the subject line of the first selected messages.
5. Under Where, select a folder for saving.
6. Under Format, choose either Rich Text Format (completely formatted email text) or Plain Text (plain text versions of email messages).
7. Click Save.

The text file contains the sender, subject, and recipients of the messages as they appear in Mail when you read them.
