Questions & Answers

As answered by people managing Postmark and Anypost.

What makes your product unique?

Anypost's answer:

Most email APIs rent their infrastructure from a cloud provider and pass the markup on to you. Anypost doesn't.

  • Bare-metal infrastructure: Anypost runs on bare-metal servers instead of rented cloud capacity, so there's no cloud markup in your bill. The efficiency is the discount.
  • Billed by the penny: As low as 5¢ per 1,000 emails at volume, with plans starting at $20/month for 100,000 emails.
  • Emails in Markdown: Write in Markdown and get responsive, email-safe HTML and plain text that render correctly in Gmail, Outlook and Apple Mail. No table hacks.
  • Backed by actual humans: When something needs attention, you reach real people who know email.

Why should a person choose your product over its competitors?

Anypost's answer:

Because you shouldn't have to choose between price, deliverability and a good developer experience.

  • Lower cost at every tier: Plans start at $20/month for 100,000 emails and drop to 8¢ per 1,000 at high volume. Free forever for up to 3,000 emails a month.
  • Deliverability handled for you: DKIM and SPF are set up automatically, and sending reputation is warmed and managed for you.
  • Every event, your way: Deliveries, opens, clicks, bounces and unsubscribes arrive as events by webhook, through the events API, or in the dashboard.
  • Unsubscribes handled: One-click unsubscribe links, a hosted unsubscribe page and automatic suppression are built in.
  • Easy to switch: Send through a simple HTTP API or SMTP, with official SDKs in 8 languages, batch sends and idempotency keys.

How would you describe the primary audience of your product?

Anypost's answer:

Businesses that send serious email volume and are tired of paying legacy email API prices for it. That includes:

  • Mid-size and larger companies sending transactional email (receipts, password resets, notifications) and broadcast email at scale
  • SaaS and e-commerce teams that want predictable costs as their volume grows
  • Engineering and marketing teams that need reliable delivery, clear event data and a platform both sides can work with
  • Teams leaving SendGrid, Amazon SES, Mailgun or Postmark because of rising costs, support frustrations or deliverability issues

What's the story behind your product?

Anypost's answer:

Anypost started as an infrastructure project with a simple question: why does sending email cost so much?

The answer was cloud markup. Most email APIs run on rented cloud infrastructure and pass that cost straight to their customers. So the team built an email platform on bare-metal servers instead, with DKIM, SPF and IP warming built in to protect deliverability from day one.

Next came the part everyone hates: building HTML emails. That led to emailmd, an open-source tool that turns Markdown into inbox-ready HTML. Markdown in, email out, no table hacks.

The platform first launched under the name unMTA in late 2025 and became Anypost in 2026. The goal hasn't changed: a modern email platform, humanity included. Built for the modern sender. Backed by actual humans. Billed by the penny.

Which are the primary technologies used for building your product?

Anypost's answer:

  • Bare-metal servers running Anypost's own mail transfer infrastructure (no cloud provider in the middle)
  • Email authentication: DKIM, SPF and managed IP warming
  • HTTP/JSON REST API and SMTP for sending
  • Webhooks and an events API for real-time delivery and engagement data
  • emailmd, Anypost's open-source Markdown-to-email-HTML renderer
  • Official SDKs for TypeScript, Python, PHP, Ruby, Go, Rust, Java and C#
