A Basin alternative built around a project inbox, not a form dashboard.
Basin is a polished form backend: point any HTML form at a Basin endpoint and submissions land in a dashboard, get forwarded to your email, and pass through built-in spam filtering. If forms are all you need, it does that job well.
mailcontact starts from a different question: where should everything a project receives go? Each project gets one inbox fed by both a form endpoint and a real email address (yourproject@mailcontact.app), with pings in Discord, Slack, email, or a webhook when something arrives.
