I missed an email that a train I was scheduled for had changed schedules on a trip earlier in the year. Why? Because Eurostar sends me maybe weekly email marketing messages that get filtered to one of my Google tabs because I maybe take them every couple years. It's probably unreasonable to expect that I'll see a reasonably last minute update though I'm not sure what a good alternative is.
I get probably 100+ emails a day that hit my inbox in some form and occasionally fairly important ones get mixed in with the mostly dross though Gmail does a pretty good job overall.
At least you got a notification your schedule had changed… I was just 5-6 hours late.
Had the same issue with amazon though. In the flood of “Information about your order” emails one had some slightly different content (but the same subject): “We haven’t received your entire return. Please contact us in 14 days or we’ll trash it and charge you.”
When I contacted them a month later I was not very pleased.
