A special notice can be sent only from the group's website in a desktop or mobile browser or from the Groups.io mobile app. Special notices cannot be sent by email because there is no way to designate an email message as a Groups.io special notice.

To send a special notice: 

1. Desktop browser: Go to the group’s website and select New Topic in the left menu.
   Mobile device: Go to the group and tap the New Topic icon at the bottom of the page.
2. On the New topic page, select the Send this message as a special notice checkbox under the message box.
3. Compose and format the message as desired.
4. Click or tap the Send button at the bottom of the page.

In the emailed message, a “[Special]” tag is added to the subject line in front of the group-specific subject tag.

Note: Group members who have set their subscription to No Email will not receive special notices.
