Warmy.io

Overview

Warmy.io is an email deliverability and warm-up tool that uses artificial intelligence to optimize email sender reputation and ensure marketing emails reach the inbox rather than spam folders. Founded in 2020 by Daniel Shnaider and Michael Shnaider, with headquarters in Tel Aviv, Israel and Vinnytsa, Ukraine, Warmy has grown to $8.4M in revenue as of 2024 with 11-50 employees. The platform automates email warm-up through "Adeline," their proprietary AI engine, which simulates real conversations with AI-generated replies, open rates, and click-throughs. Adeline automatically opens emails, marks them as important, removes them from spam folders, and gradually increases sending volume to build sender reputation organically. This mimics natural human email behavior, signaling to email providers that the sender is legitimate and trustworthy. Key features include automated email warm-up with customizable daily volumes, Email Health Monitoring with real-time grades for inbox placement and blacklist status, SPF/DKIM/DMARC verification, daily deliverability reports with visual insights, Team & Agency Mode to manage dozens of accounts across organizations, and Inbox Network Customization to select quality-based warm-up peers. The platform integrates with all major email service providers and SMTP servers. Warmy.io serves sales teams, marketing agencies, recruiters, and anyone running cold email outreach campaigns who needs to maintain high deliverability rates. The platform is particularly valuable for businesses scaling outbound email programs, agencies managing multiple client accounts, and companies recovering from deliverability issues or spam complaints. Pricing starts at $49/month for the Starter plan with 100 daily warm-up emails, while the Platinum plan costs $429/month and allows up to 5,000 daily warm-up emails. Multiple pricing tiers accommodate solo users through large agencies managing hundreds of mailboxes. In 2025, Warmy rolled out powerful new features including domain-level reporting from the User Dashboard, real-time report tracking, downloadable reports in XLSX or PDF format, and enhanced analytics for troubleshooting deliverability issues. These updates help users identify and fix problems before they impact campaign performance. What sets Warmy.io apart is its focus on AI-powered automation and its extensive warm-up network. Rather than simple scheduled sending, Adeline makes intelligent decisions about engagement patterns, email content, and sending behavior to maximize reputation gains. The platform's warm-up network of thousands of real email accounts ensures diverse, authentic interactions that email providers recognize as legitimate activity. This results in higher inbox placement rates, better sender scores, and improved campaign performance.
