Tagging records and sending an email to them

Hi there - i have a list of records on a screen in softr in a table. I want the user to be able to tag them, then send them all an email (probably from a form), anyone think of how to do this, automation part is easy but the frontside tagging in the list has be stumped

You could try adding a checkbox field.
This triggers the automation.
I have something similar, and the final part of the automation unchecks the checked box so that it can be run again if necessary.
