Seedlisting Reinvented: Smarter Features, Wider Reach

We’re Focused on One Thing:

Email Deliverability That Works.

InboxAlly is positioned as a warm-up tool, relying mainly on simulated opens and replies to boost sender reputation. While this can help in the short term, it doesn’t provide deep insights into where your emails actually land—Inbox, Spam, or Promotions.

At Warmy.io, we go further: our platform not only warms up your inbox but also gives you real deliverability insights. With advanced seedlist testing, Gmail/Outlook/Yahoo placement checks, and detailed reporting, you get actionable data to improve performance. And you can start with a free inbox placement test in seconds—no sign-up required.

Why Warmy.io is the Smarter Choice for Email Deliverability

More powerful technology

Advanced warm-up, automated tests, real-time alerts, and far beyond a basic seedlist.

Our technology combines advanced warm-up processes with automated inbox placement tests and real-time alerts, so you know exactly when your deliverability is at risk and how to fix it. Unlike InboxAlly, which mainly relies on simulated engagement.

Warmy gives you a clear, data-backed view of where your emails really land—Inbox, Spam, or Promotions.

With Warmy, you’re never left on your own. Our dedicated human support team is always available to guide you, listen to your challenges, and adapt our recommendations to your specific situation. Where InboxAlly mostly leaves users with a “one-size-fits-all” solution, we believe in personal, ongoing support that makes a difference.

very business is different, and your email deliverability strategy should reflect that. Warmy offers tailored solutions by industry, goals, and special requirements—whether you’re a SaaS company, an agency, or a high-volume sender. We adjust our tools and recommendations to your context, giving you a level of customization you simply won’t find in InboxAlly.

InboxAlly offers only a narrow scope of functionality, while Warmy delivers a complete suite of deliverability tools. From blacklist monitoring and DNS checks to spam testing, API access, and detailed reporting, you get more features with fewer restrictions—all designed to help you not just warm up, but master your email deliverability.

Warmy delivers greater functionality at a lower cost. You don’t have to sacrifice volume or advanced tools because of pricing tiers. Compared to InboxAlly, you’ll get higher sending capacity, richer insights, and more automation—without paying extra for every upgrade.

Warmy isn’t just a tool—it’s powered by a team of in-house deliverability researchers who are constantly analyzing trends, running experiments, and pushing the limits of what’s possible in inbox placement. This means our technology evolves faster and stays ahead of industry changes, while InboxAlly’s static approach quickly falls behind.
