There are multiple ways to message your group. You can message directly from the platform or you can send or forward a message to the group from your email client using the Group Email Address.
On the group settings, choose Email Settings and add the group email address you would like to use.
Enabling the toggle Group Discussions means your members can see each others' comments on posts. This is great for discussion and collaboration groups where member engagement is encouraged or desired. If members want to opt out of receiving comments on a particular thread, they can choose Opt Out at the bottom of any message they receive.
