Streamline Vendor Communications Without the Risk

AI drafts purchase orders and vendor emails with proper business context. Your procurement team reviews before sending to prevent costly errors.


Why this matters

Vendor communication is repetitive and time-consuming, but errors carry significant consequences. A wrong quantity on a purchase order, an incorrect specification, or a miscommunicated delivery date can cause supply chain disruptions that cost far more than the time saved by automation. Teams need speed without sacrificing accuracy.


How MultiMail solves this

MultiMail's AI agent handles routine vendor communications — purchase orders, delivery schedule requests, quality feedback, and contract renewal discussions. It drafts professional emails with proper business context and attaches relevant specifications. Gated_send oversight ensures procurement reviews PO details and pricing before anything reaches the supplier.

1

Identify Communication Need

Your AI agent detects vendor communication triggers — low inventory alerts, scheduled reorders, delivery date requests, or quality inspection results.

2

Gather Business Context

The agent pulls relevant data: contract terms, agreed pricing, delivery schedules, past order history, and specifications from your procurement system.

3

Draft Professional Communication

Using the gathered context, the agent drafts a clear, professional email with all necessary details — quantities, pricing, delivery requirements, and attached specifications.

4

Procurement Reviews and Approves

Under gated_send, the draft enters the approval queue. Procurement verifies quantities, pricing, and terms before the email is sent to the vendor.


Implementation

Generate Purchase Order Email
python
import requests

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

def draft_purchase_order(po: dict, vendor: dict):
    items = "\n".join([
        f"- {item[&"cm">#039;name']}: {item['qty']} units @ ${item['price']:.2f}"
        for item in po["items"]
    ])

    body = (
        f"Dear {vendor[&"cm">#039;contact_name']},\n\n"
        f"Please find below purchase order "cm">#{po['id']}:\n\n"
        f"{items}\n\n"
        f"Total: ${po[&"cm">#039;total']:.2f}\n"
        f"Requested delivery: {po[&"cm">#039;delivery_date']}\n"
        f"Ship to: {po[&"cm">#039;ship_to_address']}\n\n"
        f"Please confirm receipt and expected delivery date.\n\n"
        f"Best regards"
    )

    response = requests.post(
        f"{API}/send",
        headers=HEADERS,
        json={
            "from": "[email protected]",
            "to": vendor["email"],
            "subject": f"PO "cm">#{po['id']} - {len(po['items'])} items",
            "text_body": body,
            "html_body": build_po_html(po, vendor)
        }
    )
    print(f"PO draft queued for review: {response.json()[&"cm">#039;id']}")

Draft a purchase order email with itemized details for procurement review.

Follow Up on Pending Deliveries
python
import requests
from datetime import datetime

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

def follow_up_overdue_deliveries(orders: list):
    today = datetime.utcnow().date()

    for order in orders:
        if order["expected_date"] < today and order["status"] != "received":
            days_late = (today - order["expected_date"]).days

            body = (
                f"Dear {order[&"cm">#039;vendor_contact']},\n\n"
                f"PO "cm">#{order['po_id']} was expected on "
                f"{order[&"cm">#039;expected_date']} and is now {days_late} "
                f"day(s) overdue.\n\n"
                f"Could you please provide an updated ETA?\n\n"
                f"Items pending:\n"
                + "\n".join(f"- {i[&"cm">#039;name']} x{i['qty']}" for i in order["items"])
            )

            requests.post(
                f"{API}/send",
                headers=HEADERS,
                json={
                    "from": "[email protected]",
                    "to": order["vendor_email"],
                    "subject": f"Delivery follow-up: PO "cm">#{order['po_id']} ({days_late}d overdue)",
                    "text_body": body
                }
            )

Check for overdue vendor deliveries and send follow-up emails.

MCP Tool Integration
typescript
"cm">// Using MultiMail MCP tools for vendor communication

"cm">// 1. Look up vendor contact
const vendor = await mcp.search_contacts({

What you get

Error Prevention on Critical Orders

Gated send ensures procurement reviews every PO detail — quantities, pricing, specifications — before it reaches the supplier. Mistakes are caught before they cause supply chain disruption.

Consistent Professional Communication

Every vendor email follows your company's communication standards. No more inconsistency between different procurement staff or hastily written emails.

Automated Follow-Up Cadence

The AI tracks delivery dates and sends follow-ups on overdue orders automatically. No more manual spreadsheet tracking to remember which vendors need a reminder.

Full Communication Audit Trail

Every vendor email is logged in MultiMail with thread tracking. When disputes arise about what was ordered or agreed, you have a complete record.


Recommended oversight mode

Recommended
gated_send
Vendor communications often involve financial commitments — purchase orders, pricing agreements, and delivery terms. Errors in these communications can cause costly supply chain disruptions. Gated send lets AI handle the drafting workload while procurement verifies every detail before sending.

Common questions

Can the AI handle negotiations with vendors?
The AI can draft negotiation emails (price adjustments, term changes, volume discount requests) for procurement review. However, complex negotiations should remain human-driven with the AI providing data and drafting support. The gated_send oversight ensures procurement controls the negotiation strategy.
How does this handle multiple vendors for the same item?
Your AI agent can compare pricing and lead times across vendors and draft POs to the optimal supplier. The procurement team reviews the vendor selection during the gated_send approval. You can also set up preferred vendor rules that the agent follows automatically.
Can I track vendor response times?
Yes. MultiMail's thread tracking logs when emails are sent and when replies arrive. Your AI agent can calculate average vendor response times and flag vendors who consistently take longer than expected to confirm orders.
Does this support attachments like specifications and drawings?
Yes. Your AI agent can attach specification documents, CAD drawings, quality requirements, and other files to vendor emails via the MultiMail API. Attachments are visible during the gated_send review so procurement can verify the correct files are included.
