Hi @mdkat ,
Would you please share an example of the vote? Does the leadership would make response to the email will support for vote?
I suggest that you could create a flow for each time when a new form ideas is created, create an item in a sharepoint list, and send the email with the item link, the list should have a number column, the leadership would reply to the email with the id of item in the email subject,such as "Response to ideas-id" The response "Support" or "Oppose" in the email body.
Then you could create another flow to trigger when a new email arrives and the subject contains string Response to ideas, then get the special item from the list with the id, check the body in the email, if it is Support, add 1 to the number column in this item.
Best regards,
Alice
