Spark only allows me to create reminders for outgoing email. I wish I could create a reminder for mail that is in my Inbox. While I can snooze that email, it just re-appears and I don’t see a notification. I am now trying the alert part of snooze to see if that works. Update: I did find that turning alert on triggers a notification that fires at the time of the snooze. If you go in to Settings, Scheduling, Snoozes and enable Default Alert then I think alerts will be on by default. If there is something important I will either dump in to Reminders or Noteplan.
