Group Messaging for Lodge

So today we canceled lodge for the weather, most of our members are seniors and didn’t want them getting sick or slipping. We have a group message but we have maxed out the number of contacts we can have in the group message and 2 of our members who aren’t in the group and can’t be added didn’t get the message. What are some ways y’all have gotten announcements out to large groups? Facebook is out, most of the members don’t have it, figure email is out too.
