What is winnr?

winnr provides bulk email accounts you can plug into any sales automation software like Apollo, Instantly, or Smartlead and achieve great deliverability at scale. Google Workspace accounts are expensive ($16+/account), have daily limits, take hours to set up, and often get suspended for cold email. winnr solves all of that — 50+ accounts in minutes at a fraction of the cost.

Does winnr integrate with tool XYZ?

Yes. Export your CSV and import into any sales automation tool — Smartlead, Snov, Instantly, Apollo, Lemlist, and more.

Does winnr have an API?

Yes! A full REST API to automate everything — domains, email users, inboxes, and more. Generate a token from your dashboard. Included with every plan at no extra cost. Learn more.

How many domains do I need?

Use our domain calculator to figure out exactly how many you need based on your sending volume.

How do I warm up the accounts?

Export your CSV and import into any warming tool — Smartlead, Instantly, Snov.io, or Lemlist. On Enterprise, we can warm them for you.

How many accounts can I get?

Startup includes 50 accounts, Enterprise includes 200. Additional accounts are $1 each/month.

Do you offer dedicated IPs?

Yes, $20/month on Enterprise. Most senders do great on shared IPs. Dedicated IPs are useful for advanced senders managing multiple mail streams.

Can I use my own domains?

Yes. Bring your own domains and we'll set up DKIM/SPF/DMARC records for you, no matter where you purchased them.

How much are domains?

One-time cost: .com/.net/.co $10 · .dev/.me $8 · .org $5 · .biz $5 · .info $2 · .xyz $1. Or bring your own for free.

Who is winnr for?

Entrepreneurs, sales teams, and demand gen agencies who want to scale cold email properly. winnr is not for spammers — we only work with legitimate businesses.

What is DKIM/SPF/DMARC?

Email authentication protocols required by Gmail and Yahoo since February 2024. We handle all of it — every winnr email has 100% passing, fully aligned SPF, DKIM, and DMARC.

Do you have an affiliate program?

Yes! 40% recurring commissions for 12 months per referral. No cap on earnings, monthly payouts. Learn more.

How do you guarantee deliverability?

Expert-level email authentication, our own infrastructure, and strict anti-spam policies. Follow our best practices and you'll see excellent results. 90% deliverability guaranteed or your money back.

How many emails can I send?

We recommend <50 emails/day per account for optimal deliverability. With 50 accounts on Startup, that's ~2,500/day after proper warmup.

How long does warmup take?

At least 2 weeks, ideally 4 weeks for new domains. The patience pays off when you're delivering thousands of cold emails per day.

Why do I need this?

To send thousands of cold emails with great deliverability without paying $16/account for Google Workspace. The goal: more leads, appointments, and demos.

What's the difference vs Google Workspace?

We run our own infrastructure, just like Google. But 50 accounts takes minutes and costs <$100/mo vs hours of setup and $300–400/mo with Google. No yearly contracts.
