Forward Emails as Attachments Without Revealing Addresses
To forward an email as an attachment without revealing all the addresses in it:
- Save the message you want to forward as a .eml or .msg file.
- Open the saved message in a text editor like Notepad.
- Delete all the email addresses you do not want to reveal.
- Usually, you can simply remove the To: and Cc: lines completely.
- In your email client, forward the original message as an attachment.
- Before sending the forward, however, delete the automatically generated attachment.
- Attach your edited .eml or .msg file instead.
- Continue composing and delivering the forward as usual.
