HotHawk vs Warmy.io
Warmy is the most feature-complete standalone warmer going, and it warms much the way HotHawk does. The difference is the model: Warmy charges per inbox behind a demo, while HotHawk bundles the same-method warmup into the sender for one flat, published price.
Choose HotHawk if
You like Warmy’s warmup but not its per-inbox bill, and you want it bundled into the sender on a Google and Microsoft only pool, with the Master Inbox and ClientBox, at one flat published price.
Choose Warmy if
You want deep standalone deliverability diagnostics, seed-list placement testing and Google Postmaster, or you need to warm Yahoo, Amazon SES or Zoho that a Google and Microsoft pool excludes.

Comparison based on publicly available information from warmy.io and hothawk.ai, accurate as of June 2026. Warmy.io removed its public prices in 2026; its pricing page now shows volume-based B2B, B2C and custom plans behind a demo, with legacy figures circulating around $49 an inbox. Pool sizes are each vendor’s own disclosed figure, not an audited count. "Not documented" means the feature is not confirmed in Warmy.io’s public material, not that it is necessarily absent. Warmy.io is a trademark of its respective owner; HotHawk is not affiliated with or endorsed by Warmy.io.
Where HotHawk wins
Same warmup, without the per-inbox bill.
We will be straight here: Warmy and HotHawk warm the same way, on real inboxes with AI-written conversations across topics, filtered out of your inbox. So the win is not the method. It is everything around it, the pool, the price and the protections.
No per-inbox bill that climbs
Warmy is charged per inbox, which reviewers say punishes growth, and warming 19 mailboxes can top $2,000 a month. HotHawk includes warmup in the platform for one flat price, with unlimited mailboxes warmed, so adding inboxes does not move the invoice.
A Google and Microsoft pool
Warmy deliberately mixes B2B and B2C inboxes, and warms consumer providers alongside business ones. HotHawk warms only against 50,000+ real Google and Microsoft inboxes, so every signal comes from the providers your B2B prospects actually use.
Bad mailboxes get pulled
A mailbox that starts bouncing is suspended on the spot, and risky ones are quarantined before they drag the pool down. Warmy monitors safe settings and rescues warmup mail from spam, but does not document quarantine or auto-suspend of mailboxes.
The price is on the page
Warmy pulled its public prices in 2026, so you book a demo to learn what it costs. HotHawk’s pricing is on the website, $97 a month all-in, with a 7-day trial and no sales call to see a number.
Where HotHawk wins
The best Master Inbox in cold email.
Warmy’s job ends the moment a prospect replies. It has no inbox, so the reply lands wherever your sender leaves it. HotHawk catches every reply and puts it in front of the right rep, which is the half of cold email a standalone warmer never touches.
It catches every reply
The Master Inbox connects to your real mailboxes and pulls in forwarded replies, CC’d colleagues, out-of-office notes and the people who reply from an address you never emailed. Warmy is warmup only, so the reply goes wherever your sender drops it.
Every reply gets an owner
Round robin shares new replies evenly across the team, and mailbox groups route them by the inbox they arrived on. Nobody has to remember to pick replies up by hand.
Each rep gets their own view
Give every rep a My Inbox of just their replies, or run one shared team inbox. Managers keep the full picture either way.
The warm ones surface first
Replies are sorted into positive, negative and out of office, so the team works the people who want to talk before chasing the rest.
Where Warmy wins
The diagnostics run deeper.
Warmy is the strongest standalone tool here on deliverability diagnostics, and it genuinely beats us there. It runs seed-list inbox-placement testing, integrates with Google Postmaster Tools for domain and IP reputation, and warms in 30-plus languages. It also warms providers our pool deliberately leaves out, Yahoo, Amazon SES and Zoho, and splits B2B from B2C inboxes. If you want a deep deliverability suite layered onto a sender we do not replace, or you need to warm non-Google and Microsoft providers, Warmy is the better buy for that job.
We made a narrower choice. Rather than build a standalone diagnostics suite, we keep warmup to real Google and Microsoft inboxes, bundle it into the sender, and put the rest of the work into sending and the replies that come back.
The verdict
Which tool should you pick?
Pick HotHawk
When you want Warmy-grade warmup bundled into the sender on a Google and Microsoft only pool, at one flat published price with quarantine and instant suspension, plus the Master Inbox and ClientBox.
Pick Warmy
When you want deep standalone diagnostics, seed-list placement testing and Google Postmaster, or you need to warm Yahoo, Amazon SES or Zoho, and per-inbox pricing is a fair trade for that.
FAQ
HotHawk vs Warmy questions.
Is HotHawk’s warmup better than Warmy’s?
Not on method, and we would not claim it is. Both warm against real inboxes with AI-written conversations across topics, and both keep warmup mail out of your inbox. The honest differences are around it: HotHawk includes warmup in the platform price rather than charging per inbox, warms only against real Google and Microsoft inboxes, and quarantines risky mailboxes. Warmy, in turn, has the deeper standalone diagnostics.
How much does Warmy cost now?
Warmy no longer publishes prices. Its pricing page shows volume-based B2B, B2C and custom plans behind a Book a demo button. Older figures put the entry plan around $49 an inbox a month, but treat that as a planning estimate, and expect the per-inbox cost to rise as you add mailboxes. HotHawk is $97 a month all-in, shown on the website, with a 7-day trial.
What is the difference between HotHawk and Warmy?
Warmy is a standalone warmup and deliverability suite you bolt onto a sender you already use. It warms inboxes and runs diagnostics. HotHawk is the platform that sends, with warmup built into every plan, plus the Master Inbox for replies and ClientBox for agencies. The warmup method is much the same; the model is not, since HotHawk bundles it in and Warmy charges per inbox on top of your sending tool.
Does Warmy support Yahoo and other providers?
Yes. Warmy warms Gmail, Microsoft, Yahoo, Amazon SES, Zoho and custom SMTP, and splits B2B from B2C inboxes. That breadth is a genuine Warmy strength. HotHawk deliberately warms only against real Google and Microsoft inboxes, so if you need to warm Yahoo or SES, Warmy is the better fit there.
Does HotHawk have deliverability diagnostics like Warmy?
No, and this is where Warmy is the stronger tool. Its seed-list inbox-placement testing and Google Postmaster integration are a mature standalone diagnostic, and it warms in 30-plus languages. HotHawk focuses on warmup, sending and replies, and runs no open or link tracking by design. If you want deep deliverability diagnostics layered onto an existing sender, Warmy is built for that.
Can I switch from Warmy to HotHawk?
Yes. You connect your own mailboxes over OAuth or SMTP, and warmup starts automatically with no separate tool to wire up. The first difference you feel is that the per-inbox warmup bill is gone, the price was on the website rather than behind a demo, and your sending and replies now live in the same place.
