Sometimes email automations are made inactive for one reason or another, and a payroll could be finalised with this setting inactive - meaning the client doesn't receive the payroll. This is even more of an issue if auto-pilot is enabled.
A column for Email automations would help know at a glance if any clients have inactive emails.
It could be a filled in circle or number of inactive addresses that shows in the list or some combination of the two to tell us as much information at a glance as possible.
I've listed under Dashboard, but that's not where this would be, it's the employer list.
