— The Pharos team
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.
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.
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.
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.
Send your first email in under a minute. Then watch the same deliverability data we use to route your mail — updated every five minutes.
curl https://api.pharos.email/v1/emails \ -H "Authorization: Bearer $PHAROS_KEY" \ -d from="you@yourdomain.com" \ -d to="user@example.com" \ -d subject="Reset your password" \ -d text="Here's your magic link."
import { Pharos } from "@pharos/node"; const pharos = new Pharos(process.env.PHAROS_KEY); await pharos.emails.send({ from: "you@yourdomain.com", to: "user@example.com", subject: "Reset your password", text: "Here's your magic link.", });
from pharos import Pharos pharos = Pharos(api_key=os.environ["PHAROS_KEY"]) pharos.emails.send( from_="you@yourdomain.com", to="user@example.com", subject="Reset your password", text="Here's your magic link.", )
We publish the same reputation data we use to decide which IP pool sends your mail. Sample figures shown.
Seed to Series B teams sending magic links, AI reports, and agent notifications at scale. Names are under NDA until public launch — here's the shape of the cohort.
Request a seat now. We onboard a small group at a time so every founder gets a deliverability engineer on the other end.
