an email to support@, hello@ or billing@ becomes a conversation in your app's admin. each address gets its own tab, and anything sent to any other address on the domain lands in "others", so nothing gets lost.
replies go out from the same address that received the email, written in markdown, with their own signature, and land in the same thread in the customer's inbox. you can see if it was delivered, bounced or marked as spam. auto replies and bounces are stored but don't trigger alerts.
here's how it's split:
resend-inbox: the core, plain php, no framework.
laravel-resend-inbox: livewire screens to drop into your admin.
resend-inbox-bundle: the same thing for symfony.
