## About sendmsg.io
sendmsg.io is a developer-first email platform for sending transactional and promotional email at scale. It combines a REST API and SDKs (Node.js, Python, PHP, Go) with built-in reputation management: Domain Health Scoring (0–100, updated continuously), adaptive rate limiting based on live ISP feedback, graduated freeze states, and gradual recovery. The Anomaly Cortex layer detects abnormal sending patterns within 30–60 seconds and automatically protects sender reputation. Transactional emails route through a dedicated priority queue and never get throttled by promotional-side issues. Built for SaaS, e-commerce, and developer-first teams sending 10K–10M emails/month.
