email.onDelivered

The recipient's server accepted the message.

Fires when the recipient’s mail server accepts the message. responseTime is included when the provider measures it.

hooks: {
  email: {
    onDelivered: async (event) => {
      await prisma.sentEmail.updateMany({
        where: { messageId: event.messageId },
        data: { status: "delivered" },
      });
    },
  },
},

Delivered means the server took the message — whether it landed in the inbox or the spam folder is not observable. When delivery fails instead, onBounced fires.
