I have a weird issue where Twitch.tv verification emails are delayed about 4 hours before I receive them. I am just using Cloudflare to route emails to another email provider, and I’m not using Cloudflare’s own custom Email routing.
I thought the delay issue was due to my email hosting provider, but then I switched hosting providers and the delay is still happening. I contacted Twitch. support but they would not help with the issue. The Twitch emails originate from an amazonses.com system.
It seems like there could be something happening with amazonses emails? I wanted to try contacting Amazon support but I’m not sure how I would do that. It seems you would need an Amazonses or some other Amazon cloud account to be able to reach them.
