Anypost
Send transactional and broadcast email from one modern API
Anypost is a modern email API for sending transactional and broadcast messages through a simple HTTP or SMTP interface. It solves the problem of high costs and complexity associated with legacy email services by offering a streamlined, efficient stack with low pricing (as low as 8¢ per 1,000 emails). Designed for developers, it provides 8 SDKs, Markdown-based email creation, and comprehensive event tracking out of the box.
Built on bare metal infrastructure managed by Anypost, the service delivers high scalability and performance. Automatic DKIM and SPF configuration ensure inbox delivery, while sending reputation is warmed and managed by the platform. Whether sending a hundred or hundreds of millions of messages, Anypost scales seamlessly with no catch.
