The only thing preventing me from migrating my mail from Fastmail to iCloud+ with my own domain is iCloud’s very basic filter support. You can’t do multiple conditions when making filters, and I’ve got 50+ folders for all kinds of filters in order to be able to tame my inbox.
Also, the ability to have just one custom domain linked to your inbox is a considerable limiting factor for me; I’ve inherited several domains over the years and I‘d like to have all of them available for receiving email while using my primary domain for sending email.
I hope Apple expands iCloud+ functionality over time so they become a serious contender to the Gmail/Microsoft 365 duopoly.
