Hi
I dont know where you plan to put the button, but if you want to send an email to 4 different locations
1. Create your Maual flow
2. Create an initial Send Email V2/or V3 action under the trigger
3. Click the + Sign between the trigger and new #2 Action
Select add Parallel Action
Select another Send Email V2/V3
Do this until you have 4 total parallel actions
Now in each Line, Add the proper To line of emails for each offer.
Now if you have the emails stored somewhere, in each parallel path, you can run an action to get the email addresses from SharePoint or wherever you want, and you just need to have an identifier, so you can say Get Items (ftiler on location name)
And bingo you have 1 button.
That, or you schedule 4 different flows to send to each office. And you have 4 separate ones, just in case time zones change. This way you dont touch a button, it just sends them every day at whatever you want you.
