I think the expectation of urgency should be put into perspective alongside the $10/year price tag, i.e. if you need someone to get out of bed in the middle of the night $10 is probably not enough incentive.
That said, any issues or questions I've had have been resolved way faster than I experienced with Fastmail.
For me, this would be a major issue for personal emails as well. Even if an undelivered email wouldn't cause a monetary loss it still could have significant consequences, such as upsetting friends or family or missing the signup deadline for your kid's sports team. Personally, I don't mind paying the higher Fastmail prices to not have to worry about this.
Maybe it's good for personal use or as a throwaway email, but it is not good for main business email. Certainly not a replacement for Gmail or Fastmail kinds. Because you expect the email service to have 24/7 availability and near-perfect email delivery and receiving.
