You are off the list
Your address has been removed from the phillylate.st records digest.
Done — your address is no longer on the list and nothing further will be sent to it.
Nothing else happens: no confirmation email asking whether you are sure, no retention copy kept aside. If you want the address deleted from the database entirely rather than just marked as removed, write to hello@phillylate.st and that is done too.
You are welcome back any time.
