Forwarding an Email as an Attachment

In some cases, you may need to forward an email as an email attachment. In contrast to simply forwarding an email, the headers of the original email are preserved, which can be necessary for troubleshooting issues such as blacklisting and bounced emails.

Please Note

Emails that you forward to IONOS Customer Service for phishing/spam checks in the .eml or .msg formats must be compressed before sending.

If you are unsure about how to compress files, please see the instructions below:

Saving Email Locally

With some email programs and webmail services, emails cannot be forwarded as attachments at all - or only with some effort. In this case, you can save the email locally and send the resulting file as an attachment.

IONOS Webmail

  • Log in to Webmail.
  • Select the desired email.

  • Click on the icon with three horizontal lines in the white bar at the top right.

  • Click Save as file.

    The email will be saved.


Gmail

  • Open Gmail.

  • Open the desired email.

  • Click on the three dots in the email.

  • Click on Download message.


Outlook 365 and 2016/2019/2021

  • Open Outlook.

  • Click on the desired message.

  • Click File at the top of the menu bar.

  • Click Save as.

  • Select the desired storage location.

  • In the File name field, type the desired file name.

  • Click Save.


Apple Mail on macOS

  • Open Apple Mail.

  • Click on the desired message.

  • Click on File.

  • Click on Save as.

  • In the Save as: field, type the desired file name.

  • In the Location: field, select the desired location.

  • Click Save.

Compressing Emails as a ZIP File

Optionally, you can compress the saved email(s) into a ZIP file, making it easier to send multiple downloaded emails at once:

Windows

  • Open Windows Explorer and navigate to the folder where you saved the email.
  • Right-click on the file. A context menu will open.
  • Select Send To > ZIP Compressed Folder. A packed version of the source file is created with the ZIP extension.


macOS

  • Open the Finder and navigate to the file.
  • Highlight the file and click the gear icon in the menu bar.
  • Click on "Compress filename" to pack the file. "Filename" will be the same as the name you gave it when you saved the email.
