Just landed two big features. SelfMailKit.com is now a complete email dashboard!
1. Native Inbox - Send, receive, and reply to emails directly from the dashboard.
2. Managed version of SelfMailKit. If you don't prefer the self-hosted version, use the managed version with Inbox

I just requested AWS SES prod access for my new account, which I deployed SelfMailKit.
Generally, it takes 1-2 business days + follow-up questions, but this time, it took less than a min and automatically granted prod access.
