Under the hood

Put your email pedal to our metal

Anypost runs on modern bare metal that we manage ourselves, not the aging software and slow, shared servers many email providers still lean on. The low price comes from real efficiency, not corners cut.

Built to reach the inbox. Automatic DKIM and SPF, with sending reputation warmed and managed for you.

Steady at any volume. Send a hundred messages or hundreds of millions; Anypost scales with you.

Low prices, no catch. A modern email stack we run ourselves, with no cloud provider's markup on your bill. The efficiency is the discount.

How you send

Point and send.

Send over HTTP or SMTP. SMTP lets existing apps and off-the-shelf software send with no code changes while HTTP offers a richer JSON interface and enhanced speed. One key authenticates both, and every send reports back the same events, whichever transport you use.

# JSON over the HTTP API.
POST https://api.anypost.com/v1/email
{
"from": "[email protected]",
"to": ["[email protected]"],
"subject": "Welcome aboard",
"text": "Thanks for joining."
}

email.delivered → your webhook

Batch in one call. Send many messages in a single request.

Idempotency keys. Attach a key and retry without fear.

emailmd

Write Markdown. Ship email. No HTMHELL.

Email HTML is a special kind of misery. With emailmd you write plain Markdown, and Anypost renders HTML that's been tested across real inboxes, plus a clean plain-text version, on every send.

emailmd is open source, with 1,000+ stars from developers who render their own email. Inside Anypost it's built in: pass markdown and the rendering happens for you. emailmd.dev →

Visibility

The send is just the beginning.

Anypost tracks every email event out of the box: sent, delivered, bounced, opened, clicked, unsubscribed. Push them to a webhook, pull them from the events API, or just open the dashboard, where every event is already there to search and filter. No event pipeline to wire up, no second system to build.

EventsLive
POST your-app.com/webhooks202

Push, pull, or just look. Webhooks POST each event the instant it happens, the events API serves the full history on demand, and the dashboard has it all without a line of code.

Opens and clicks, as events. Engagement arrives the same way everything else does, so the code that handles a delivery already knows how to handle an open.

Slice by anything. Attach tags, a topic, and a campaign to any send, then filter every event by them. Pull up just the bounces from one campaign, or every click on a single topic.

Unsubscribes, handled. Anypost adds the one-click unsubscribe link, hosts the page, and suppresses the address automatically. You still get the unsubscribe as an event, like everything else.

SDKs

Speak your stack

Official SDKs for eight languages, each one idiomatic and a single install away. Or skip the SDK entirely: the API is plain HTTP and JSON, so curl works just as well. Whatever you reach for, the docs and full API reference are ready.
