Hi Paul, email is one-way communication and not guaranteed to be delivered. At a minimum you should have monitored who did and did not respond to the email with some kind of action and those that did not should have more effort expended to be able to reach them. Finally, you should have kept the data for a reasonable amount of time (say 90 days) post shut-down so users that did not get the notification could download it. What you've done is super rude and if I were still a customer in an unaffected region it would definitely be reason enough to leave because it's pointless to sit and wait to see how you'll deal with my data when the time comes. Better to preempt that and leave while I still have control.
