We help individuals and startups send personalized cold emails at scale — directly from their own Gmail or Outlook, without any technical setup or extra costs.
ColdFly started with a simple idea: cold emails shouldn’t require expensive tools or complicated servers. We built a platform that lets users send up to 300 personalized emails a day — with attachments and name tags — using their own inbox.
From side-hustlers to small sales teams, we’ve helped hundreds of users reach the right people, faster and more effectively.
As we grow, our mission stays the same: to make outreach smarter, not harder.
At ColdFly, our values drive everything — simplicity, transparency, and empowering users to take control of their outreach.
We believe in simplifying cold outreach with powerful tools that stay easy to use.
Your emails, your account. We never send from our servers — your data stays with you.
From performance to UI, we obsess over every detail so you don’t have to.
