Email infrastructure,
built by the people who run it

Winnr was founded in 2024 by a team of email deliverability engineers who spent years managing SMTP servers, MTA clusters, and IP reputation at scale. We built the platform we wished existed.

Why we built Winnr

Before Winnr, our team ran email infrastructure for agencies sending millions of outbound emails per month. We saw the same problem everywhere: sales teams were paying $16+ per account for Google Workspace, spending hours on manual DNS setup, and getting suspended without warning for doing exactly what they signed up to do.

The alternatives weren't much better. Most "cold email infrastructure" providers were reselling Google Workspace or Microsoft 365 at a markup, offering no real control over deliverability. The few that ran their own servers were expensive, opaque about their infrastructure, and locked customers into annual contracts.

We knew there was a better way because we'd been building and operating SMTP infrastructure for years. So we built Winnr: a platform where sales teams get fully authenticated email accounts on dedicated infrastructure in minutes, not hours. Every account gets proper SPF, DKIM, and DMARC from day one. Every customer gets the same enterprise-grade infrastructure we'd been running for our own clients.

Small team, deep expertise

Everyone who works on Winnr has hands-on experience operating mail servers, debugging DNS records, and managing IP reputation.

Engineering

Infrastructure & Platform

SMTP server operations, MTA configuration (KumoMTA, Postfix), DNS automation, API development, and the dashboard you use every day. Over a decade of combined experience running mail at scale.

Deliverability

Reputation & Compliance

IP warm-up strategy, blocklist monitoring, feedback loop management, and sender reputation optimization. We actively manage the infrastructure that keeps your emails in inboxes.

Support

Customer Success

Real humans who understand email infrastructure, not scripted chatbots. We respond to every support request and help customers optimize their setup for maximum deliverability.

What we believe

Own the infrastructure

We don't resell Google Workspace or Microsoft 365. We operate our own SMTP servers, manage our own IP pools, and control every layer of the stack. When something goes wrong, we can actually fix it.

Authentication is non-negotiable

Every email account ships with fully aligned SPF, DKIM, and DMARC from the moment it's created. Gmail and Yahoo made authentication mandatory. We've had it since day one.

Transparent pricing

No annual lock-in, no hidden fees, no "contact sales" pricing. Two plans, clear per-account costs, and you can cancel anytime. We compete on product quality, not contract length.

API-first

Everything in Winnr is available through our REST API. Domains, mailboxes, warming, sending, inbox monitoring. If you can do it in the dashboard, you can automate it.

Purpose-built for cold email

A distributed network of SMTP clusters and MTA nodes across multiple providers and regions.

Smart Routing

Our MTA layer handles outbound delivery, IP rotation, rate limiting, and bounce processing. Traffic is automatically routed to maintain optimal deliverability.

Reputation Monitoring

We monitor sender reputation across all major inbox providers in real time. Dedicated IPs are available for customers who want full control over their sending reputation.

Automatic DNS

SPF, DKIM, DMARC, and MX records are provisioned automatically when you add a domain. No manual zone file editing, no waiting for propagation.
