Anypost

Anypost is a transactional and broadcast email API and SMTP service built for developers and teams who need reliable email delivery without legacy pricing. Anypost gives you a modern email infrastructure platform for sending everything from password resets and receipts to newsletters and marketing campaigns, backed by the same delivery pipeline and event reporting regardless of which transport you use. Two ways to send: a fast, JSON-based HTTP API (POST to api.anypost.com/v1/email) for teams building custom integrations, or standard SMTP for plugging into existing apps and off-the-shelf software with zero code changes. One API key authenticates both, and official SDKs are available for TypeScript, Python, PHP, Ruby, Go, Rust, Java, and C#, alongside full support for plain HTTP requests. Anypost's core object model, Team, Domain, API Key, Message, Event, and Webhook, gives you strict data isolation and real-time delivery visibility. Every send generates trackable events (sent, delivered, bounced, complained, opened, clicked) pushed to your webhook endpoint the moment they happen, so you always know what's landing and what isn't. Built-in suppression management automatically protects your sending reputation by blocking mail to addresses that hard-bounce or complain. Deliverability is handled for you: automatic DKIM/SPF signing and managed sending-reputation warmup come standard, so new senders don't have to manually configure authentication or slowly build trust with mailbox providers. Templates let you store reusable subject lines, HTML, and text with variable placeholders, and Anypost's open-source emailmd renderer lets you write plain Markdown and get back HTML tested across Gmail, Outlook, Apple Mail, Yahoo, Thunderbird, and mobile clients, plus an AI template generator that turns a plain-language description into a full email template. What makes Anypost different from legacy email APIs is infrastructure: it runs on bare metal rather than marked-up cloud infrastructure, which is how it keeps pricing a fraction of what established providers charge. Every account starts free for up to 3,000 messages a month, with adaptive daily sending limits and flexible prepaid overage credits for teams that scale beyond it. Anypost is an over-deliver, under-budget alternative to legacy transactional and broadcast email providers, combining API and SMTP flexibility, built-in deliverability tooling, real-time event tracking, and developer-friendly pricing in one platform.
