For our October 21st Courier Live, Avi Goldman joined me to talk about building Interactive Emails using Parcel. Parcel is a code editor built for email development. It streamlines your development workflow to help you rapidly code high-quality emails. Together we walked through building an Interactive Welcome Email that prompts the recipient to select how they want to be contacted. We then used these selections to add the recipient to the appropriate Courier Lists.

Check out the video below to watch us:

  • Talk about Parcel and Interactive Emails
  • Build an Interactive Welcome Email using Parcel
  • Add the Interactive Welcome Email to Courier using the Handlebars Override
  • Connect the email submission using email tracking to a Glitch App running Node.js and ExpressJS
  • Send and Demo the finished email

Code for the Node.js/ExpressJS server and email html can be found in the Courier-Parcel Glitch application.

Is there something you’d like to see us do using Courier? Let us know and it might be the subject of our next Courier Live. We stream a new Courier Live every Wednesday at noon Pacific. Follow us on Twitch to be notified when we go live.

The $5.9 Billion Rebuild: Why Healthcare Is Replacing Its Notification Infrastructure

The clinical alert and notification market will reach $5.9 billion by 2032, growing at 12.3% annually. That number represents hardware, software, and services combined. It also represents healthcare's admission that pagers and overhead speakers aren't enough anymore. Healthcare organizations are rebuilding how critical information moves through their systems. Regulatory pressure, workforce shortages, and value-based care economics are forcing the investment. The software layer is where outcomes are won or lost.

Vibe Coding Notifications: How to Use Courier with Cursor or Claude Code

Courier's MCP server lets AI coding tools like Cursor and Claude Code interact directly with your notification infrastructure. Unlike Knock and Novu's MCP servers that focus on API operations, Courier's includes embedded installation guides for Node, Python, Flutter, React, and other platforms. When you prompt "add Courier to my app," your AI assistant pulls accurate setup instructions rather than relying on outdated training data. OneSignal's MCP is community-maintained, not official. Courier supports 50+ providers, native Slack/Teams integration, drop-in inbox and preference components, and a free tier of 10,000 notifications/month. Configure in Cursor with "url": "https://mcp.courier.com" and "headers": { "api_key": "YOUR_KEY" }.

The Complete Guide to B2B Customer Engagement

Courier provides the notification infrastructure layer for B2B customer engagement, routing messages across email, SMS, push, in-app, Slack, and Teams based on user preferences and product events. Unlike building notification systems in-house—which takes months of engineering time for features like multi-channel routing, preference management, and delivery tracking—Courier handles this infrastructure so product teams can focus on engagement strategy. B2B customer engagement requires multiple layers: notification infrastructure (Courier), customer data platforms (Segment), product analytics (Mixpanel/Amplitude), and channel-specific tools. Companies with strong engagement programs see 15-25% churn reduction. The key is connecting product events to customer communication at the right moment through the right channel, handling complexity like multiple users per account with different notification needs across work channels.
