Announce Features That Matter to Each Customer

AI personalizes product announcements based on each customer's plan and usage patterns. Marketing reviews before every send.


Why this matters

Product announcements often fail to land because every customer gets the same generic message regardless of their plan, usage, or needs. Features that would delight power users get buried alongside updates irrelevant to new customers. The result is low engagement, missed adoption opportunities, and announcement fatigue.


How MultiMail solves this

MultiMail's AI agent analyzes each customer's plan level and usage patterns to personalize announcement messaging. Customers see how new features specifically benefit their workflow. With gated_send oversight, product marketing reviews every announcement for accuracy and brand alignment before delivery.

1

Define the Announcement

Provide the feature details, affected plans, and key benefits. The AI agent identifies which customer segments are most impacted by the update.

2

Segment by Usage and Plan

The agent uses search_contacts to group customers by plan tier, feature usage, and engagement level, creating targeted segments that each receive relevant messaging.

3

Personalize Each Announcement

Using send_email, the agent drafts announcements that reference each customer's actual usage. A heavy API user learns about new rate limits differently than a dashboard-only user.

4

Marketing Approves

With gated_send, all drafts enter the approval queue. Product marketing reviews messaging accuracy and brand consistency before the announcements ship.


Implementation

Send a Personalized Product Announcement
python
import requests

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

response = requests.post(
    f"{API}/send",
    headers=HEADERS,
    json={
        "from": "[email protected]",
        "to": ["[email protected]"],
        "subject": "New: Webhook support is live on your Pro plan",
        "text_body": (
            "Hi team,\n\n"
            "Great news! Webhooks are now available on your Pro plan. "
            "Based on your API usage patterns, here&"cm">#039;s how webhooks "
            "can replace your current polling setup:\n\n"
            "- Real-time email delivery notifications\n"
            "- Instant inbox triggers (no more polling every 30s)\n"
            "- Reduced API calls by ~60%\n\n"
            "Get started: https://docs.yourcompany.com/webhooks"
        ),
        "html_body": "<h2>Webhooks Are Live</h2><p>Hi team...</p>"
    }
)
print(f"Announcement queued: {response.json()[&"cm">#039;id']}")

Announce a new feature with messaging tailored to the customer's plan and usage.

Segment Customers by Plan
python
import requests

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

"cm"># Find Pro plan customers who use the API heavily
pro_users = requests.get(
    f"{API}/contacts/search",
    headers=HEADERS,
    params={"query": "pro-plan api-user"}
).json()

for customer in pro_users["results"]:
    print(f"Customer: {customer[&"cm">#039;name']} ({customer['email']})")
    "cm"># Draft personalized announcement for each

Search contacts to build targeted announcement lists by plan tier.

MCP Tool: Announcement Campaign
typescript
"cm">// Find customers on Pro and Scale plans
const proCustomers = await mcp.search_contacts({
  query: "pro-plan",
  limit: 200
});

"cm">// Send personalized announcements
for (const customer of proCustomers.results) {
  const result = await mcp.send_email({
    to: customer.email,
    subject: "New: Webhook support is live on your Pro plan",
    text_body: `Hi ${customer.name}, webhooks are now available...`
  });

  await mcp.tag_email({
    email_id: result.id,
    tags: ["product-announcement", "webhooks-launch", "pro-segment"]
  });
}

Use MCP tools to manage a product announcement campaign across customer segments.


What you get

Higher Feature Adoption

When customers see exactly how a new feature benefits their specific workflow, adoption rates increase dramatically compared to generic announcements.

Reduced Announcement Fatigue

Customers only receive announcements relevant to their plan and usage. No more tuning out product emails because most updates don't apply.

Accurate Messaging Guaranteed

Gated send ensures product marketing reviews every announcement for factual accuracy. Incorrect feature descriptions or pricing details never reach customers.

Segment-Level Insights

Track engagement by customer segment to understand which features resonate with which audiences, informing future product and marketing decisions.


Recommended oversight mode

gated_send
Product announcements shape customer expectations about features and pricing. Inaccurate descriptions could cause confusion or support escalations. Gated send lets AI personalize at scale while marketing ensures accuracy and brand consistency.

Common questions

How does the AI know what features matter to each customer?
Your AI agent uses customer metadata — plan tier, API usage patterns, feature adoption data, and engagement history — to determine relevance. A customer who heavily uses email threading will get excited about threading improvements, while a customer who only uses basic sending might not need that update.
Can we stagger announcement sends across segments?
Yes. Your AI agent can schedule sends by segment priority. For example, send to power users first to catch issues, then roll out to the broader customer base. Gated send lets you approve each segment's batch independently.
What if a feature only affects certain plans?
The AI agent filters recipients by plan tier automatically. Customers on plans without access to the new feature can receive a separate message highlighting the upgrade path, or be excluded entirely. This prevents confusion about feature availability.
How do we measure announcement effectiveness?
Track email engagement through MultiMail's API and correlate with feature adoption metrics from your product analytics. The tag_email tool lets you categorize announcements for easy cross-referencing with adoption data.
