🥊 The AWS Calendar Invite Server : The Secret Weapon for Event Management
Why Adding the AWS Calendar Invite Server to Your Event Stack Is the Knockout Punch
Executive Summary
Most Event Management Platforms (EMPs) — like Eventbrite, Cvent, Luma, and Splash — handle logistics well, but can’t get on the calendar fast and stay there.
The AWS Calendar Invite Server (CIS) changes that.
It sends real calendar invites at scale, with native RSVP handling. Combined with traditional platforms, it becomes the knockout punch: faster engagement, lower friction, and reliable delivery of updates, reminders, and cancellations.
All based on the AWS stack. It bolts on in less than 1 Hr into a AWS account and can send millions of Calendar Invites.

💡 Why It Matters
1. First to Calendar Wins Attention
Most platforms send emails asking users to register. CIS sends the event directly to their calendar.
✅ On the calendar = commitment
❌ In the inbox = ignorable
2. Reminders & Updates That Actually Work
CIS uses .ics file updates with higher SEQUENCE numbers — which calendar clients recognize immediately.
No spam folder. No missed message. Just synced.
3. No Login = Higher RSVP Rates
Users RSVP right inside Outlook, Gmail, or Apple Calendar — no forms or friction.
Lower friction = higher conversion = more attendees.
4. Time-Based Messaging > List-Based Blasting
CIS uses event time as the trigger, not static mailing lists.
5. It's Not a Replacement. It's an Upgrade.
CIS doesn't compete with EMPs — it extends them:
EMP forms ➝ instant calendar invites
CRM/ESP ➝ calendar-aware campaigns
APIs ➝ direct calendar injection
🔌 Technical Integration Scenarios
Form-Based: Auto-send calendar invites post-registration
API: Pre-registration or 1-click calendar injection
CRM/ESP: Embed invite links in Mailchimp, Klaviyo, etc.
CSV Upload: Drop lists into CIS for batch sends
📦 For EMP Vendors: Why You Should License CIS
Own the Calendar UX: Don't let Google/Apple take the credit
Differentiate: Be the platform that guarantees visibility
Boost Activation: Especially for free RSVP events
Instant Feedback: See real-time RSVP responses
🏁 Closing Argument
Most platforms get events onto a web page. AWS Calendar Invite Server gets them onto the calendar.
Add the AWS Calendar Invite Server — and turn your platform into the fastest, smartest, most effective engagement engine out there for pennies per send.
It’s not the whole stack. It’s the knockout punch.
