My loss isn't as big as this but I've gotten some Paypal disputes because those users didn't get any of the welcome emails (for a rather costly purchase). My issue has been more with Apple's mail for some reason though. Thankfully all my customers have been super understanding and were kind to take the disputes back once they were able to locate the emails in the Spam folder. Also I finally decided to just use a "reputed" smtp server to fix my problems (feels like extortion but what can you do). I've written this before, but it's so sad that something so important and vital like email is so broken and we are the mercy of corps like Google/Apple/Microsoft and everyone has their own secret policy.
