Fill Every Seat with Personalized Invitations

AI tailors event invitations based on each recipient's interests and past attendance. Marketing reviews before every send.


Why this matters

Generic event invitations have low open and registration rates because they feel mass-produced. Personalizing invitations at scale is impossible without automation — but fully automated sends risk off-brand messaging or targeting the wrong audience segments.


How MultiMail solves this

MultiMail's AI agent segments your audience, personalizes each invitation based on recipient interests and past event attendance, and queues everything for marketing review. Gated_send oversight ensures every invitation is on-brand and properly targeted before delivery.

1

Define Event and Audience

Set up the event details — date, speakers, topics, registration link. The AI agent uses search_contacts to identify the target audience based on interest tags and engagement history.

2

Segment and Personalize

The agent groups recipients by interest, role, and past attendance, then crafts a unique pitch for each segment highlighting the most relevant speakers or topics.

3

Draft Invitations

Using send_email, the agent composes personalized invitations for each recipient with tailored subject lines, opening hooks, and calls to action.

4

Marketing Reviews

With gated_send oversight, all invitations enter the approval queue. Marketing reviews messaging, targeting, and branding before approving for delivery.

            "Based on your interest in agent frameworks, I thought you&"cm">#039;d "
            "enjoy our upcoming webinar on building AI agents with email " 
            "capabilities.\n\n"
            "Date: March 20, 2026 at 2pm ET\n"
            "Speaker: Jane Smith, Head of AI Platform\n\n"
            "Register here: https://events.yourcompany.com/webinar-march\n"
        ),
        "html_body": "<h2>You&"cm">#039;re Invited</h2><p>Hi Rachel...</p>"
    }
)
print(f"Invitation queued: {response.json()[&"cm">#039;id']}")

Compose and send a personalized webinar invitation through the MultiMail API.

Segment Audience by Interest
python
import requests

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

"cm"># Find contacts interested in AI agents
ai_segment = requests.get(
    f"{API}/contacts/search",
    headers=HEADERS,
    params={"query": "ai-agents"}
).json()

"cm"># Find contacts interested in developer tools
dev_segment = requests.get(
    f"{API}/contacts/search",
    headers=HEADERS,
    params={"query": "developer-tools"}
).json()

print(f"AI segment: {len(ai_segment[&"cm">#039;results'])} contacts")
print(f"Dev segment: {len(dev_segment[&"cm">#039;results'])} contacts")

Search contacts by interest tags to build targeted invitation lists.

MCP Tool: Event Invitation Workflow
typescript
"cm">// Find contacts interested in the event topic
const audience = await mcp.search_contacts({
  query: "ai-agents",
  limit: 200
});

"cm">// Send personalized invitations
for (const contact of audience.results) {
  const result = await mcp.send_email({
    to: contact.email,
    subject: `${contact.name}, join our AI agents webinar March 20`,
    text_body: `Hi ${contact.name}, based on your work in AI...`
  });

  "cm">// Tag for campaign tracking
  await mcp.tag_email({
    email_id: result.id,
    tags: ["event-invite", "webinar-march-2026"]
  });
}

Use MCP tools to search contacts, send invitations, and tag for tracking.

Common questions

How does the AI personalize each invitation?
The agent uses contact metadata — interest tags, past event attendance, role, and company — to craft relevant messaging. For a developer, it might highlight the technical workshop. For a product manager, it might emphasize the strategy keynote. Each invitation feels individually written.
Can we send follow-up reminders to non-registrants?
Yes. Your AI agent can track which recipients haven't registered and send follow-up reminders with adjusted messaging. With gated_send, marketing approves the reminder copy before it goes out, ensuring the follow-up cadence feels helpful rather than pushy.
How do we handle event cancellations or changes?
The agent can draft update notifications for all registered attendees using the same personalization approach. Gated send is especially valuable here, as incorrect event details could cause confusion and damage trust.
Does this integrate with our event platform?
MultiMail handles email delivery. Your AI agent connects to your event platform (Eventbrite, Luma, etc.) for registration data and uses MultiMail's API to send invitations. The agent bridges both systems without requiring native integration.
