How Top Fintech Startups Engage Users

This past month, I interviewed over 50 FinTech executives, primarily CTOs, VPEs, CPOs and engineering managers at mid-market product orgs. In each of these conversations, I had one central question in mind: “How do you currently manage notifications for your company?”  

Below are a few key observations and one surprising takeaway.

Notifications are the central communication channel between the product and the market—the direct touch point between you and your users. Notifications are how your users will interact with you and how they will remember you. This is why having the right platform for managing event-driven notifications is one of the most important channels for user engagement, growth and retention.

This is especially true for fintech companies, where users need to know when their accounts are active, when their margin calls are issued, or when their transactions are declined. Even a few missed financial product alerts can have lasting repercussions for consumers and businesses alike, which is precisely why it’s increasingly important to have a multi-channel templating system—to have each notification be cross-compatible with multiple channels, ranging from SMS to email to Slack. That way, you can reach your users where they want to be reached. Of course, sending too many notifications can have an adverse effect, so it’s important to give users control over their preferences.

Every executive I’ve spoken to has told me that a rapidly scaling technology company needs a robust system in order to manage notification templates in a user-friendly way.

In short, any stakeholder, whether product manager or engineer, should be able to edit copy, reformat messages, analyze engagement, and track delivery with distribution channels and routing systems to ensure that notifications are properly delivered. Redundancy needs to be in place from the beginning so that if a user has opted out or a provider is down, the message will automatically route through another channel. Data security and regulatory compliance is another top priority in fintech, meaning any system implementation needs to also have enterprise-level protections such as encryption of data in transit and at rest, SOC 2 certification and GDPR/CCPA.

But building a system this robust takes thousands of engineering hours and a princely fortune to get right. Good executives know the value of strong technical systems and cannot afford to skimp on quality. The tradeoff is usually price and time.

What it takes to build Notifications

The most noteworthy observation from my many interviews came from a product leader of a rapidly-growing unicorn startup. In order for their business to stay operational, they needed to communicate with users on a regular basis—anything from ‘thank you for signing up’ to ‘there is a problem with your account, please login to review.’ In short, they needed a multichannel templating system so they built one in-house.

It cost them over 4000 engineering hours just to build template management, and much much more to build routing and message delivery microservices. All in all, their cost of building a notifications system internally was more than one million dollars. The worst part is they aren’t alone. Everyone I spoke with is sinking countless hours building the exact same capabilities as everyone else I spoke with.

For a long time, there were no good alternatives, this was just the cost of doing business. That is, until now. Courier is the easiest way to build and manage notifications over any channel.

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.

quite hours and delivery windows
EngineeringNotifications Landscape

How Top Notification Platforms Handle Quiet Hours & Delivery Windows in 2026

No platform offers per-template delivery windows in 2026—it's either per-workflow (Customer.io, Knock), per-campaign (Braze), or global settings. This comparison shows exactly how six platforms handle quiet hours and send time controls based on their documentation and API specs. Braze leads on AI timing (23% open rate lift from Intelligent Timing across their customer base). Novu is the only platform letting subscribers set their own delivery windows. Customer.io and Knock require manual workflow configuration. OneSignal's strength is push-specific optimization across 300K+ apps. Courier combines per-node flexibility with API control. Includes feature matrix, timezone handling, and frequency capping differences.
