Warmy
Warmy.io is an email deliverability platform that automatically warms up email accounts, monitors sender reputation, and checks spam placement to keep cold and marketing emails out of spam folders.

Warmy works in the background of a user’s email account, sending and interacting with a network of other addresses to build up sender reputation before a new domain or mailbox starts cold outreach or bulk sending. Alongside warmup, it checks inbox placement, flags blacklist issues, and monitors domain health metrics like SPF, DKIM, and DMARC setup. It’s aimed at the technical, often-overlooked plumbing of email marketing rather than the writing or sending tools themselves.
Who It’s For
Affiliates writing for cold email and outbound sales audiences, agencies running email marketing for clients, and SaaS founders doing their own outreach are the clearest fit, since deliverability problems are a common pain point in those spaces. It pairs naturally with content about cold email tools, SDR workflows, or email marketing platforms as a companion recommendation rather than a standalone topic. Because deliverability is a technical concept many readers don’t think about until they hit spam-folder problems, it often converts better paired with educational content than as a bare product mention.
