Warmy.io

Warmy.io handles email warmup through its AI-powered Adeline engine, which automatically manages sending volume, timing, and engagement patterns to build domain reputation. The platform gradually increases your sending rate while monitoring deliverability metrics. It connects to your existing email provider and stops warming up once your account reaches safe reputation thresholds.

Cold email campaigns fail without good sender reputation, and Warmy solves that problem upfront. It's built for agencies, SaaS companies, and B2B teams running outbound at scale who can't risk low deliverability rates. Unlike manual warmup or basic alternatives, Warmy's AI removes the guesswork from volume ramping so you can focus on campaign strategy.
