Does Klaviyo have a way to conditionally send an email to a person depending on whether (or how recently) you have already sent that email to that person? I have only figured out how to condition on how recently you have sent any email to that person, or on whether or how recently the person has been in that Flow as a whole.
My use case is, there are users with accounts (each user may have many accounts), and when an account is inactive I want to send periodic email notifications to the user. I don't want to send the notification if I have already sent the user a notification about that account in the past N days, but I do still want to send the notification even if I have already sent the user a notification about a different account in the past N days.
The events and profile properties that I use to implement this will be custom, so there is flexibility there, but I would prefer not to have to keep track of Klaviyo-related state/logic outside of Klaviyo - I want to be able to give updates to Klaviyo saying that a given account of a given user has been inactive for a given number of days, and for logic within Klaviyo to determine whether that warrants sending a notification that day or not.
