For those who use Apple (@icloud, @me, @mac.com) accounts: my apologies for the almost comical delays (days) in delivery times for these emails. I’ve determined my current email provider is not willing or able to fix this issue, so I’m in the process of transitioning email delivery services – will try and keep this ‘behind the scenes’ work as unobtrusive as possible!
