Email runs through everything

Resend handles every email the site sends. Payment confirmations after Stripe checkout. Welcome emails when someone joins the newsletter. Notification emails when I update a project, add a deliverable, post a comment, or assign an action item. Each one is a single API call from a Next.js route handler — no email service dashboard, no template builder, no drag-and-drop editor. The templates are React components. The same TypeScript that renders the site renders the emails. The git log shows email touchpoints scattered across a dozen commits because email is not a feature — it is infrastructure. Every service interaction eventually produces an email. The client buys a mixing package and gets a confirmation. I upload stems and they get a notification. The newsletter subscriber gets a welcome. One provider, one API, one pattern. Resend and a single import statement.
