Submission confirmation email sent within 5 minutes with a status link

When a submitter clicks submit and gets no email back, they assume the form dropped the request and either re-submit (creating duplicate moderation work) or abandon the directory entirely. Confirmation emails with a tracked submission ID and status link reduce duplicate submissions, cut support volume on "did you get my listing?" tickets, and give the business a legitimate re-engagement channel when the listing is approved. Absent confirmation also breaks CAN-SPAM and GDPR Article 13 transparency expectations around acknowledging data collection at the point of intake.

In app/api/listings/submit/route.ts, generate a stable submission_id inside the same transaction that inserts the listing, then enqueue the confirmation email so the response is not blocked by SMTP latency. The email body must include the ID and a status URL the submitter can revisit:

await sendEmail({
  to: data.contactEmail,
  subject: 'Your listing submission has been received',
  html: `Submission ID: ${submissionId}<br><a href="https://yourdomain.com/submissions/${submissionId}/status">Check Status</a>`
})

Queue the send via a background job so the API returns within 500ms.

• ID: directory-submissions-moderation.moderation.confirmation-email

• Severity: high

• What to look for: After a submission is created, check whether a confirmation email is sent to the submitter. The email should contain: (1) a unique submission reference ID, (2) a link to check the status (approved/pending/rejected), (3) sent within 5 minutes. Look for email templates and background job logic.

• Pass criteria: Enumerate all relevant code paths. A confirmation email is sent to the submitter's email within 5 minutes of submission. The email includes a submission ID and a link to check the status (e.g., /submissions/:id/status). with at least 1 verified instance.

• Fail criteria: No confirmation email is sent, or the email is sent but lacks a status link, or the email takes longer than 5 minutes to arrive.

• Skip (N/A) when: The project has no email infrastructure.

• Detail on fail: "Users receive no confirmation after submitting a listing. They don't know if the submission was received or when it will be reviewed." or "Email sent but contains no way to track the status."

• Remediation: Send a confirmation email with a status link:

  // app/api/listings/submit/route.ts
  import { sendEmail } from '@/lib/email'
  import { v4 as uuidv4 } from 'uuid'
  
  export async function POST(req: Request) {
    const data = await req.json()
  
    const submissionId = uuidv4()
    const listing = await db.listings.create({
      data: { ...data, submission_id: submissionId, status: 'pending' }
    })
  
    // Send confirmation email
    await sendEmail({
      to: data.contactEmail,
      subject: 'Your listing submission has been received',
      html: `
        <p>Thank you for submitting your listing to our directory.</p>
        <p><strong>Submission ID:</strong> ${submissionId}</p>
        <p>Your listing is currently being reviewed by our team. You can check the status anytime:</p>
        <p><a href="https://yourdomain.com/submissions/${submissionId}/status">Check Status</a></p>
        <p>We'll send you an email once your listing is approved or if we need more information.</p>
      `
    })
  
    return Response.json({ id: listing.id }, { status: 201 })
  }
