# Notifications

> Send transactional emails and marketplace notifications with Resend.

<Note>
  This guide is being written. The outline below is the intended structure.
</Note>

<Info>
  **Two notification surfaces.** Mercur sends provider-backed transactional email (seller approvals, invites, order events) *and* keeps an in-app vendor notification feed in the Vendor Portal. The email side uses Medusa's standard notification-provider model — Resend is the documented default, but any Medusa notification provider plugs in the same way.
