Outbound sales teams, lead generation agencies, recruiters, and resellers running cold email at scale
About Winnr
Winnr is a cold email infrastructure platform that runs the full sending stack in one place. Teams register outreach domains inside the dashboard, generate SMTP mailboxes that come with DKIM, SPF, and DMARC records already published, and enroll them in automated warmup. A shared inbox aggregates replies across every mailbox, and credentials export in one click to sequencers such as Smartlead or Instantly. Agencies and resellers can provision infrastructure programmatically through the REST API and webhooks. Continuous deliverability monitoring surfaces DNS drift and blacklist issues before they affect campaigns. Compared with running dozens of Google Workspace inboxes, Winnr cuts cost dramatically and reduces setup from days to minutes.
