Nitrosend

Nitrosend is a transactional email API designed specifically for AI agents and applications that need reliable delivery of system notifications. It includes a built-in MCP server for smooth integration with AI workflows, pre-built templates for common use cases, and the ability to route emails across multiple providers to optimize for delivery and cost.

The platform works well for developers building AI-native applications who want transactional email without the complexity of connecting to multiple services. It's lighter-weight than full customer data platforms but more flexible than simple SMTP relays, making it a fit for teams that prioritize agent compatibility and provider choice.
