Winnr

What it does

Winnr gives outbound teams cold email infrastructure at scale: buy domains, spin up SMTP mailboxes with automatic DKIM, SPF and DMARC, and warm them up — all in under 10 minutes, at a fraction of Google Workspace pricing. Unified inbox for replies, one-click CSV export to Smartlead/Instantly, webhooks, and an API. Unlike renting mailboxes from an agency, you own the whole stack.

Cold email infrastructure from $69/mo: SMTP mailboxes with automatic SPF, DKIM and DMARC, domains, built-in warming and pre-warmed mailboxes ready to send.

SMTP mailboxes with automatic DKIM, SPF & DMARC, one-time domain purchases, built-in warming and pre-warmed mailboxes. Plans from $69/mo for 50 email accounts. Cold email infrastructure is the set of sending domains, mailboxes and DNS records your outbound email goes through. It is kept apart from your company's main domain, so outreach can't hurt the email your team relies on every day. With Winnr you get SMTP/IMAP mailboxes on Winnr's own sending infrastructure, not Google Workspace or Microsoft 365 seats. You buy domains as a one-time purchase or connect your own, and SPF, DKIM and DMARC are set up automatically on every domain. Warming is built in, pre-warmed mailboxes are there when…from winnr.app
