What Our Review Didn’t Cover

This comparison focused on solo cold emailers and small-to-mid sales teams. We didn’t test enterprise plan tiers with custom SLAs or evaluate large agency pack deployments running thousands of mailboxes. Our observations are based on the April 2026 versions of both tools. If you’re sending over 100,000 emails per day, your priorities may differ from what we’ve covered here.

Veredicto final

Maildoso and Warmy are two very different products. Maildoso is a cold email infrastructure provider that handles your sending domains, mailboxes, and IP rotation. Warmy is a deliverability tool that warms up email accounts you already own.

Warmy is excellent for boosting existing sender reputation and avoiding the spam folder. The deliverability test tool and template checker provide real value. Smaller companies that already have email accounts often find Warmy a solid choice.

However, if you need full cold email infrastructure with unlimited inboxes, master inbox, and automated DNS setup, Maildoso is the better choice. Most cold email marketers need infrastructure first, then warm up — and Maildoso bundles both.

Perguntas frequentes

O que é Maildoso?

Maildoso is a cold email infrastructure provider that lets you send emails at scale. It gives you unlimited email inboxes across three domains or five domains and handles the entire domain configuration, domain name setup, and email server provisioning for you. The platform reduces costs and saves time compared to manually buying domains, mailboxes on Google Workspaces or Microsoft Outlook, and a private IP address. Maildoso pricing starts at $100/month for the small package, with built-in domain rotation, automated warm up, and a private warmup pool — making it a true email warmup automation and email warmup service in one. The system also guarantees domain isolation so your client domains stay free of viruses and protected from cross-contamination, with a clean subdomain structure for each agency pack.

Is Maildoso good for beginners?

Yes, Maildoso is user friendly because it automates the parts that other cold emailers struggle with. You don’t have to manually configure SPF, DKIM, DMARC, or even the warmup process — the system handles email setup end-to-end. The monthly subscription is private to your account, with no shared IP risk, and the dashboard tracks open rate, reply rate, click rate, and deliverability rate so you can monitor metrics in real time. The starter package is cost effective for solo users, while the agency pack and enterprise plan give you more inboxes for lead generation at scale. There is no free trial, but the deliverability platform pays for itself quickly through better inbox placement.

O que faz Warmy?

Warmy is the warmup software behind Warmy.io — an AI-powered warm-up tool and deliverability checker that uses Adeline AI as its AI email assistente to run the warmup process. It helps your warm-up emails and outreach emails land in the primary inbox instead of the spam folder. Warmy email warm up uses real users and real inboxes that hold natural conversations through your account, building domain authority and improving sender reputation. Warmy features include a deliverability test, an email deliverability test, a spam folder test, an email seed list, an email seed network across providers, a template checker that scans every subject line and spam test, a spam score checker, blacklist removal alerts via a built-in blacklist monitor, Google Postmaster Tools integration, an email signature construtor doubling as a signature generator, and a free SPF generator. Warmy integrations with major email platforms make it a strong choice for teams serious about deliverability.

Como funciona o aquecimento por e-mail?

Email warmup gradually increases sending volume from a new account so messages get delivered reliably. The tool sends warm-up emails to a network of inboxes that open, reply, and join the conversation through automated warm up — building sender reputation slowly without triggering any spam filter. The domain warm up phase is crucial for the highest deliverability rate and gives you more control over how providers see you. Watch your open rate, reply rate, and click rate climb as the warmup process matures.

O que é infraestrutura de e-mail frio?

Cold email infrastructure is the technical setup used to send emails at scale for outreach. It includes sending domains, mailboxes, three dedicated IPs or shared IPs, a private IP, DNS records, and a clean email server. The unlimited plan tiers from providers like Maildoso let you avoid extra cost when scaling, with no surprise fees.

Is Warmy worth it and is Warmy good for cold email?

Yes — for teams that struggle with the spam folder, Warmy is worth it. Warmy pricing is custom-quoted by plan, so contact sales for exact figures; the Warmy login dashboard gives you a free email warmup taste of the experience for new accounts. Warmy customer support is responsive, and Warmy alternatives like Warmbox or Mailwarm exist but lack Adeline AI as an assistente de IA and the inbox placement test depth. Each warmup email sent through the system helps improve sender reputation gradually. The Warmy app and Warmy free trial period help you confirm it’s the best email warmup tool, best email warmup, best email deliverability fix, and best deliverability tool for your stack before committing.
