A developer's alternative to Intercom for product notifications
Intercom renamed itself Fin and agreed to be acquired by Salesforce, both around its AI support agent. If you're using it to send your product's notifications, it's fair to ask what the platform was actually built for. Its API answers the question: there is no push or SMS send endpoint, and the campaign builder has no API at all. Here's the architecture, the cost math, and how to migrate transactional and marketing sends.
Product notifications API: what it handles and how to build
A product notifications API sits between your product's events and every channel you send on. You post an event, and the API decides what message goes out, to whom, on which channel, at what time, with that user's preferences applied.

A developer's alternative to Salesforce Marketing Cloud
Salesforce Marketing Cloud is expensive, hard to navigate, and needs its own specialist developers to run. The answer isn't leaving Salesforce. It's keeping your CRM as the system of record and moving message delivery to a surface your own engineers, marketers, and AI agents can build on. Here's the architecture, the cost math, and an honest look at when to stay.
Courier Skills: teach your AI agent to build with Courier
Courier Skills is a free, open-source knowledge base that teaches your AI coding agent how to build and debug notifications with Courier: the right primitive for each use case, the exact payload shapes, and the mistakes that produce unhelpful errors.

The federal texting rule your transportation and logistics software is breaking
A single text to a driving trucker can trigger a federal fine of up to $11,000 for the motor carrier, and your transportation and logistics software is often what sent it. How to design driver notifications that stay on the right side of FMCSA rules.
How to send messages and not piss off your customers
