Three quick fields. We review requests in small batches and email you when a seat opens.

By invitation only. We onboard a small cohort at a time and never share your details.

What Pharos is

Other email APIs ship features. We ship inbox placement.

Resend has beautiful docs on someone else's infrastructure. Postmark knows deliverability but its UI is from 2015. Pharos is what happens when the people who run real email infrastructure build a modern developer API on top of it. You buy credits, you send email, it arrives.

Why founders switch

Three things every other API makes you choose between.

Deliverability is built in

We monitor our own IP reputation 24/7 and publish the data. Automated rDNS/PTR scanning, DKIM/SPF/DMARC setup, and deliverability engineers who answer tickets — not a chatbot.

Built for developers in 2026

A modern REST API with idempotency keys, signed webhooks, and an OpenAPI spec. SDKs for Node, Python, PHP, and Ruby. Docs written by engineers, with examples that actually work.

Pay for what you send

Buy credits in bulk, use them whenever. No subscriptions, no overage fees, no surprise bills. Credits don't expire, and the per-email cost is shown at checkout.

Proof, not promises

One call to send. Live data to prove it landed.

Send your first email in under a minute. Then watch the same deliverability data we use to route your mail — updated every five minutes.
