How to Build a Scalable MarTech Stack: Lessons from a Sold-Out Event

Building a MarTech Stack That Survives Sold-Out Events

Picture this: 700 dealer tables vanish faster than Disney FastPasses during spring break. That’s exactly what happened at last year’s FUN show – and why building reliable marketing tech matters more than ever. When hundreds of dealers and thousands of collectors depend on your systems, your MarTech stack can’t afford an off day.

1. CRM: Your Dealer Central Station

Managing hundreds of coin dealers (each with unique needs) taught us one hard truth: CRM systems either bend or break under pressure. When shared tables and special requests start flooding in, you need more than basic contact management.

Salesforce or HubSpot: Making the Right Choice

After testing both platforms through multiple events, here’s what we found:

• Salesforce handles complex relationships best – perfect for tracking shared tables between dealers
• HubSpot’s visual workflow builder saves time for smaller teams

Here’s how we updated dealer statuses in HubSpot during crunch time:

// Sample HubSpot API call for dealer status updates
fetch('https://api.hubapi.com/crm/v3/objects/dealers', {
method: 'PATCH',
headers: {
'Authorization': 'Bearer YOUR_ACCESS_TOKEN',
'Content-Type': 'application/json'
},
body: JSON.stringify({
properties: {
table_assignment: 'A302',
payment_status: 'confirmed',
shared_with: 'JDRC'
}
})
});

What Actually Worked: Blending Both Worlds

For the 2026 FUN show, we connected Salesforce (dealer hub) with HubSpot (attendee comms). This dynamic duo delivered:

• Live table availability maps
• Automatic waitlist promotions
• Smart matches between dealers and serious collectors

2. Customer Data: Connect the Dots

When we spotted 575 listings with shared tables and hidden dealers, it clicked: scattered data creates chaos. A proper customer data platform (CDP) became our secret weapon, merging:

• Table reservation patterns
• Email response history
• Dealer negotiation styles
• Even Disney passholder status (yes, that mattered!)

Build vs Buy: Our Event-Tested Approach

We combined Snowplow for raw data with Segment for connecting identities. Here’s how we tracked key actions:

// Event tracking implementation
window.snowplow('trackStructEvent', {
category: 'Table Reservation',
action: 'Shared Table Request',
label: 'Broward County',
property: 'table_300',
value: 1
});

72-Hour CDP Crash Course

1. Find every data source (we discovered 12 unexpected ones!)
2. Link identities using emails and mobile numbers
3. Create live dashboards showing dealer capacity

3. Email Systems: Beyond Bulk Sends

When user GoldFinger1969 asked “Does it usually sell out?”, we realized: collectors crave real-time updates. Our email setup evolved into a notification powerhouse for:

• Waitlist position changes
• Last-minute table openings
• Dealer arrival alerts

Our Email Toolbox

We mixed SendGrid for instant alerts, Mailchimp for newsletters, and Postmark to ensure delivery. The glue? Smart webhooks like this:

// SendGrid inbound webhook for engagement tracking
app.post('/sendgrid-webhook', (req, res) => {
const event = req.body[0];
if (event.event === 'processed') {
updateDealerStatus(event.email, 'email_pending');
}
if (event.event === 'delivered') {
triggerSMSFallback(event.email, 'email_delivered');
}
});

5 Emails That Actually Get Opened

1. Sneak peek with top dealers highlighted
2. Confirmation email with clickable floor plan
3. Countdown message with local tips
4. Live updates using AMP email tech
5. Post-show recap featuring biggest deals

4. Handling the Rush: Tech That Scales

When tables disappear in 3 hours, your tech must handle:

• Traffic spikes bigger than Space Mountain lines
• 500+ dealers updating inventory simultaneously
• Real-time sync between all systems

Going Serverless: Our Safety Net

We rebuilt reservations using:

• AWS Lambda for critical functions
• DynamoDB for lighting-fast updates
• CloudFront for caching heavy assets

// AWS Lambda function for table reservations
exports.handler = async (event) => {
const dealerId = event.queryStringParameters.dealerId;
const table = await checkTableAvailability(dealerId);
if (table.available) {
await updateCRM(dealerId, table.number);
await sendConfirmationEmail(dealerId);
return { statusCode: 200, body: JSON.stringify(table) };
}
return { statusCode: 409, body: 'Conflict' };
};

Stress-Test Like Your Event Depends On It

Simulate:

• Dealers hammering refresh at opening
• 10,000+ users viewing floor plans
• Payment system webhooks firing nonstop

Key Takeaways From the Trenches

Sold-out events don’t forgive tech mistakes. Build your MarTech stack to handle:

1. Flexible CRM setups for complex dealer needs
2. Unified customer views through CDPs
3. Smart email systems that notify in real-time
4. Auto-scaling infrastructure for demand spikes

When coin values swing and collectors rush like it’s Rise of the Resistance, your marketing tech keeps everything running. Build systems ready for the frenzy – your dealers (and sanity) will thank you.
