Hi
So if your current Sharepoint list stores email address and Full Name, you can implement a flow that will send one independent email per sharepoint item, meaning each target email address will receive its own email. You can add in the body Dear <full name> so you customize its contents also.
"The email going out will vary each time, announcing either an activity that members can participate in like Habitat for Humanity or a Health Fair as examples. "
So, either each person in your list has a preferred activity list associated, or you suggest then activities in a random way... you will probably need to have a second Sharepoint list with activities name, details etc. so you do not need to modify your flow everytime you want to add a new event.
Happy flowing!
