MailWarm vs Warmy 2026: Pricing, Features, Verdict

MailWarm charges a flat $90 to $190 per year, per MailWarm's pricing page. Warmy hides its rate behind a demo and prices by volume instead. If your cold email motion books meetings worth real revenue, a warmup tool that lands 5% more mail in spam is money walking away, and these two tools solve that problem very differently.

How much do MailWarm and Warmy cost in 2026?

MailWarm's Basic plan is $90/year for 50 inboxes capped at 40 emails/day. Pro is $190/year for unlimited inboxes at 80 emails/day, per MailWarm's pricing page. Warmy skips public pricing entirely, routing every plan through a 7-day free trial and a demo call, per Warmy's pricing page.

That opacity is the part nobody says out loud about volume-based warmup pricing. It usually means you pay more once you're locked into the workflow and can't compare rates upfront. If you run a lean shop and want to budget in five minutes, MailWarm's flat annual fee wins on that alone. If you're an agency negotiating for 40+ client domains, Warmy's custom quote can undercut a flat per-inbox model at scale.

What do MailWarm and Warmy actually do differently?

MailWarm is a straight warmup engine. Connect an inbox through one of 10+ supported providers, and real recipients open, read, and reply to build sender reputation, per MailWarm's site. Warmy bundles warmup with a seed list tool, deliverability insights, and email verification, positioning itself as a broader deliverability suite rather than a single-purpose tool, per Warmy's site.

Neither tool sends your cold outreach. Most teams pair either one with a sending platform like Smartlead, Instantly, or ReachInbox, and the only thing that matters downstream is whether the warmed inbox actually lands.

Which integrations and team sizes fit each tool?

MailWarm covers the basics well: Gmail, Outlook, Yahoo, AOL, SMTP, ProtonMail, Zoho Mail, Apple Mail, and FastMail. That's enough for almost any small sending stack. Warmy focuses on Google Workspace and Microsoft 365 for B2B senders, with a separate B2C track for Gmail, Yahoo, and Outlook, plus API access for teams that want to pipe warmup data into their own reporting.

Team size is the real dividing line. MailWarm's inbox caps (50 on Basic, unlimited on Pro but still one flat rate) suit a founder or a two-person team running a handful of domains. Warmy's B2B/B2C split, dedicated deliverability expert, and optional customer success manager are built for agencies juggling client domains where one bad domain can sink a whole book of business.

Verdict: which warmup tool should you pick?

Here's the honest read. MailWarm is the better buy if you're a solo operator or small team running under 50 mailboxes and want to know the bill before you sign up. Warmy is built for agencies managing many client domains, where a named deliverability expert and volume pricing beat a flat annual fee at scale. Most operations under 5 inboxes don't need Warmy's overhead. Most agencies past 20 client domains outgrow MailWarm's inbox caps fast.

Neither tool fixes a bad list or bad copy. Warmup only protects the sender reputation you've already built.

FAQs: MailWarm vs Warmy

Is MailWarm free?
MailWarm offers a 1-inbox free warmup option per its homepage, but paid plans start at $90/year for 50 inboxes on the Basic tier.

Does Warmy publish its pricing?
No. Warmy runs B2B Sender, B2C Sender, and Custom plans on volume-based pricing with no published rate, per Warmy's pricing page. You get real numbers after a 7-day trial or a demo call.

Which tool is better for agencies?
Warmy, mainly because of its dedicated deliverability expert, optional customer success manager, and volume pricing built for managing many client domains at once rather than one flat per-account rate.

Can I use MailWarm or Warmy alongside ReachInbox, Smartlead, or Instantly?
Yes. Both are standalone warmup tools that run independently of your sending platform, so they pair fine with ReachInbox, Smartlead, Instantly, or any other cold email tool you already use.

If picking a warmup tool is where your outbound stalls, that's usually a sign the bigger problem is unmanaged infrastructure, not the software.
