The context of what I said is important, even though I now realize I did not include the important determiner "less" (which I will add below).

>> If new members are made aware that sending a message to the group is perfectly acceptable, then there will be [less] trepidation.

>> Much like what I am doing here to what I assume is a group exceeding 100+ members.

> This is not a group, we’re not all receiving a notification because of your message.

My point was taking the risk of putting oneself "out there" for a group to see, not notification policies.
