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.


Try it with your agent

Pick your platform, copy the prompt, and paste it to your AI agent — it sets up MultiMail and builds the whole flow. Nothing to fill in.

1. Get MultiMail ready: read https://multimail.dev/llms.txt, connect the MCP server, create a free inbox, and set up a verified sender. 2. In Customer.io, use existing person attributes, events, segments, and campaign activity to identify customers eligible for this product announcement; trigger from a campaign or segment membership change using Customer.io's native workflow tools. 3. Build three announcement versions for new customers, active regular users, and power users, using plan level, recent events, and feature usage to explain the specific workflow benefit for each customer. 4. Compose the emails in MultiMail, schedule them by segment, and exclude customers who recently received a major product announcement to reduce fatigue. 5. Run the campaign in gated_send mode so product marketing reviews every message before delivery; ask me only for Customer.io access, sending-domain approval, and current brand guidance before going live.

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.

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 set_tags tool lets you categorize announcements for easy cross-referencing with adoption data.
