Notification strategy for product teams: what to build, what to buy, and how to decide between transactional and marketing sends.

Top Platforms for Preference Management in 2025
73% of users unsubscribe from poorly targeted notifications. The problem: preference logic is scattered across marketing platforms, product notification systems, and multiple providers that don't talk to each other. Most preference tools handle marketing OR product notifications, not both. This guide compares 9 platforms for 2025, evaluating integration depth, compliance support (GDPR, CAN-SPAM, TCPA), and multi-channel capabilities across email, SMS, push, chat, and in-app. Includes SDK references, implementation examples, and MCP setup for AI-assisted configuration. Best for teams planning Q1 notification infrastructure improvements.

Twilio Integrations with Courier: SMS, SendGrid, Segment
Twilio owns critical notification infrastructure: SMS in 180+ countries, SendGrid for email at scale, and Twilio Segment for customer data. Using them together means maintaining three APIs, three credential sets, and zero coordination between channels. Courier gives you a single integration point for all three Twilio products. Connect your accounts, use one API to send across SMS and email, start journeys from Twilio Segment events, and orchestrate multi-channel delivery with routing rules and failover built in.

Nodemailer Alternative: Outgrowing DIY Email Infrastructure
Nodemailer works great for transactional email in early-stage products. But B2B customer journeys demand more: Slack notifications for engineering teams, Microsoft Teams messages for enterprise customers, in-app notification centers, SMS escalations, and push alerts. Building this yourself means maintaining integrations with SendGrid, Twilio, Firebase, Slack's API, and Microsoft Graph. Courier provides omnichannel notification infrastructure through one API, handling routing, preferences, delivery, and analytics across every channel.

What is the Twilio Messaging API?
Twilio's Messaging API enables developers to send and receive SMS, MMS, WhatsApp, and RCS messages at scale across 180+ countries. While Twilio excels at reliable message delivery through carrier networks, modern applications need more than single-channel messaging. Courier acts as a provider-agnostic orchestration layer that activates messaging across Twilio and other channels from a single platform. You get intelligent routing, user preference management, and fallback logic without vendor lock-in.

Top 10 Rules for SMS Messaging
Transactional SMS gives you 160 characters to communicate something critical, and that drops to 70 the moment an emoji or curly quote sneaks into the copy. This guide covers 10 rules for delivery confirmations, security alerts, and payment notifications: leading with the outcome, making your brand unmistakable, respecting the character limit, making the next step obvious, keeping links trustworthy, sharing just enough context, handling security scenarios, getting timing right, offering a real escape route, and building templates that survive production data. Each rule includes weak and better versions of a real message with exact character counts.

What Most People Get Wrong About Push Notification Metrics
Push notification analytics have evolved beyond traditional engagement metrics, yet many teams still rely on outdated measurement approaches that obscure real business value. The challenge lies in applying email marketing metrics to push notifications without considering fundamental differences in user behavior and platform constraints. A notification that never gets "opened" might still drive a purchase decision or prevent user churn.
