https://github.com/winnr-app: Cold email infrastructure: domains, inboxes & warming

We built Winnr after watching outbound teams burn days (and budgets) stitching together domains, DNS records, mailboxes, and warmup tools just to start sending. Google Workspace pricing makes 50+ inboxes painful, and renting mailboxes means you never own your infrastructure. With Winnr you buy domains, get SMTP mailboxes with DKIM/SPF/DMARC configured automatically, and warm them up, all in under 10 minutes. There's a unified inbox for replies, one-click export to Smartlead/Instantly/any sequencer, webhooks, and an API for agencies and resellers. Happy to answer any questions about deliverability, warmup, or how we run the infrastructure under the hood. If you're doing cold outreach, we'd love your feedback.
