How to Apply Email Rules to Emails Containing Attachments in Google Workspace

Next comes 3. If the above expressions match, do the following. Here, you get to choose what to do with any emails matched by this compliance filter. Modify message offers the following options:

Headers – lets you add custom headers to emails. For example, you can add a custom header matching the description you entered for the setting. This helps analyze why an email was routed in a certain way or what triggered a filter.

Adding the X-Gm-Original-To header is useful when you reroute a copy of an email, and the new recipient wants to know the original recipient’s address. The latest recipient can see the original recipient by checking the X-Gm-Original-To header box in the email.

Add X-Gm-Spam and X-Gm-Phishy headers to indicate if the email is spam or phishing. For example, these headers will look like this:

X-Gm-Spam: 0 (means that the email is not spam)

X-Gm-Spam: 1 (means that the email is spam)

Prepend custom subject allows you to add something to the beginning of emails’ subjects.

Change route allows you to re-route emails to another mail server, already added to the Hosts setting as shown here.

Change envelope recipient allows you to change the email recipient to another email address, bypassing the original recipient.

Bypass spam filter for this message approves emails for delivery automatically, regardless if Gmail’s built-in spam filter thinks they are spam.

Remove attachments from this message strips the emails of all attachments.

Add more recipients adds extra recipients to the email. This acts similar to a BCC, so the sender and recipients of the message won’t know about the additional recipients you have added.

Encryption (onward delivery only) makes it mandatory for a secure connection to be established during the transmission of the email, otherwise, it will not be delivered.
