When I changed ISP I decided to use a webmail account, so I should never need to update my email address online again - in theory.
In practice I had no luck receiving emails from AmigaKit until I had added their domain to whitelists in the webmail settings first. Since then it’s been fine. But I’ve had the exact same problem with almost all my retro-related websites - including this one.
It’s a right pain in the arse and there’s not a lot AnigaKit can do about that.
