Hold Suppliers Accountable With Data-Driven Reports

AI generates quality performance reports with defect data and corrective actions. Your quality team reviews before sending to suppliers.


Why this matters

Manual supplier quality reporting is inconsistent and often delayed. Quality engineers spend hours compiling defect data, calculating metrics, and writing corrective action requests. Suppliers don't receive timely feedback, leading to recurring quality issues that impact production.


How MultiMail solves this

MultiMail's AI agent aggregates quality data, generates performance reports with trend analysis, and drafts emails with corrective action requests. With gated_send oversight, quality managers verify defect data accuracy and corrective action requirements before reports reach suppliers.

1

Aggregate Quality Data

The AI pulls inspection results, defect reports, and delivery metrics from your quality management system. It calculates key metrics like defect rates, on-time delivery, and trend comparisons.

2

Generate Performance Report

The agent compiles the data into a structured quality report with scorecards, trend charts, and specific corrective action requests for any metrics below threshold.

3

Quality Manager Reviews

With gated_send, the quality team verifies defect data accuracy, reviews corrective action priorities, and adjusts the tone based on the supplier relationship.

4

Send and Track Response

Approved reports are sent to supplier quality contacts. The agent monitors for supplier responses and tracks corrective action progress.


Implementation

Generate Supplier Quality Report
python
import requests

API = "https://api.multimail.dev/v1"
HEADERS = {"Authorization": "Bearer mm_live_xxx"}

def send_quality_report(supplier: dict, metrics: dict):
    corrective_actions = []
    if metrics["defect_rate"] > 0.02:
        corrective_actions.append(
            f"Defect rate at {metrics[&"cm">#039;defect_rate']*100:.1f}% "
            f"(target: <2.0%). Root cause analysis required."
        )
    if metrics["on_time_delivery"] < 0.95:
        corrective_actions.append(
            f"On-time delivery at {metrics[&"cm">#039;on_time_delivery']*100:.1f}% "
            f"(target: >95%). Delivery improvement plan needed."
        )

    body = (
        f"Hi {supplier[&"cm">#039;quality_contact']},\n\n"
        f"Please find your Q1 2026 quality performance summary:\n\n"
        f"Defect rate: {metrics[&"cm">#039;defect_rate']*100:.1f}%\n"
        f"On-time delivery: {metrics[&"cm">#039;on_time_delivery']*100:.1f}%\n"
        f"Units inspected: {metrics[&"cm">#039;units_inspected']:,}\n\n"
    )
    if corrective_actions:
        body += "Corrective actions required:\n"
        body += "\n".join(f"- {ca}" for ca in corrective_actions)

    return requests.post(
        f"{API}/send",
        headers=HEADERS,
        json={
            "from": "[email protected]",
            "to": supplier["email"],
            "subject": f"Q1 2026 quality report - {len(corrective_actions)} corrective actions required",
            "text_body": body
        }
    ).json()

Compile quality metrics and send a performance report with corrective action requests.

Track Corrective Action Responses
python
import requests

API = "https://api.multimail.dev/v1"
HEADERS = {"Authorization": "Bearer mm_live_xxx"}

"cm"># Check for supplier responses
inbox = requests.get(
    f"{API}/mailboxes/quality-mailbox-id/inbox",
    headers=HEADERS,
    params={"status": "unread"}
).json()

for message in inbox["emails"]:
    email = requests.get(
        f"{API}/emails/{message[&"cm">#039;id']}",
        headers=HEADERS
    ).json()

    # Tag by corrective action status
    if "corrective action plan" in email["text_body"].lower():
        requests.post(
            f"{API}/emails/{email[&"cm">#039;id']}/tags",
            headers=HEADERS,
            json={"tags": ["ca-response", "plan-submitted"]}
        )
        print(f"CA plan received from {email[&"cm">#039;from']}")

Monitor supplier responses to quality reports and track corrective action progress.

MCP Tool Integration

Use MultiMail MCP tools for supplier quality communication.


What you get

Consistent Reporting Cadence

AI ensures quality reports are generated and sent on schedule every quarter, eliminating the delays common with manual reporting.

Data-Driven Accountability

Reports include specific metrics, trend analysis, and threshold comparisons that give suppliers clear, objective performance feedback.

Accurate Before Delivery

Gated send ensures quality managers verify defect data and corrective actions before reports reach suppliers, preventing relationship-damaging errors.

Corrective Action Tracking

Thread tracking and tagging create a complete record of quality communications, corrective action requests, and supplier responses for ISO 9001 audits.


Recommended oversight mode

Recommended
gated_send
Supplier quality reports contain sensitive performance data and corrective action requests. Errors in defect rates or unwarranted corrective actions could damage supplier relationships. Gated send ensures quality managers verify all data before delivery.

Common questions

How does this help with ISO 9001 compliance?
ISO 9001 requires documented supplier quality management including performance evaluation and corrective actions. MultiMail provides an audit trail of all quality communications, corrective action requests, and supplier responses that auditors can review.
Can I customize report formats by supplier?
Yes. Different suppliers may have different quality requirements and reporting formats. The AI can adapt the report structure based on supplier tags while maintaining consistent underlying metrics and methodology.
What if a supplier disputes the quality data?
The AI monitors replies for dispute language and tags them for quality manager review. The thread tracking maintains the complete conversation history so the quality team can respond with supporting evidence and documentation.
How do I track corrective action completion?
Tag corrective actions by status (requested, plan-submitted, in-progress, verified-complete). The AI can send automated follow-up reminders when corrective action plans are overdue based on the requested timeline.
