About Warmy.io
What it does
Warmy.io solves cold email deliverability by automatically warming up your email account. It connects to a network of real inboxes (business or consumer) to send and reply to messages in a natural pattern, training spam filters that your address is legitimate. AI-driven algorithms optimize settings to help emails land in the primary inbox, not spam or promotions.
Who it's for
Best for sales teams, agencies, founders, and affiliates sending cold outreach at scale. Also for anyone recovering from a spam complaint or blacklist. Not ideal for warm email lists where deliverability is already healthy.
Real use cases
Use Warmy.io to warm up new Gmail, Outlook, or custom SMTP accounts before a campaign. Monitor deliverability metrics and spam score in real time. Set custom warm-up schedules to match your sending pattern. Integrates via API for advanced workflows.
Alternative to manual warm-up
Instead of manually sending and replying to emails, Warmy.io automates the process with a real inbox network, reducing risk and saving hours weekly.
