MailToaster vs Warmy 2026: Which Warmup Tool Wins?

MailToaster charges a flat $29 per mailbox per month, full stop, per mailtoaster.ai's own pricing page. Warmy has gone the other way: as of 2026 it pulled all dollar figures off warmy.io/pricing and routes every visitor to a demo call instead. If you're scaling past 10 mailboxes, that gap in pricing transparency should decide half your evaluation before you even test either tool.

How much does MailToaster cost vs Warmy in 2026?

MailToaster is $29 per mailbox per month on a flat plan, per mailtoaster.ai's pricing page, with no separate tiers to compare. Warmy removed its published pricing in 2026 and now sells through demo calls.

Third-party reviews from mailreach.co and mailivery.io cite its prior five-tier range at roughly $49 to $429 per month, and one mailreach.co calculation puts 20 warmed mailboxes on Warmy near $1,000/month. The same 20 mailboxes on MailToaster run $580/month, no sales call needed.

What's actually different in how they warm up your inboxes?

MailToaster runs a set path: pick New Email Account or Reputation Protect, and it auto-generates warmup emails, filters them into separate folders, and validates SPF, DKIM, and DMARC along the way. Warmy leans on AI behavior tracking and seed lists that test where emails actually land, inbox, spam, or promotions, before you send a cold email.

Most cold email platforms, Instantly and Smartlead included, now bundle basic warmup for free. That's the real pressure on both tools: a standalone product only earns its price by doing something the built-in version skips, DNS validation for MailToaster, placement testing for Warmy.

Does Warmy do more than email warmup?

Yes. Warmy bundles email list verification, spam-placement seed testing across 20+ providers, and a direct Google Postmaster Tools integration, per warmy.io. MailToaster stays narrow on purpose: warmup and the DNS checks that support it, nothing more. If your stack already has a verifier, you're paying for unused surface area on Warmy. If you're managing a dozen domains with no other monitoring, that surface area is the point.

Which one should you actually use?

If your only problem is warming up mailboxes before a cold outbound push, MailToaster is the better buy. It's cheaper, the price is public, and the trial is twice as long. Most teams under 20 mailboxes are overpaying for a full deliverability suite when a $29-flat tool does the job. Warmy earns its keep when you need monitoring, verification, and warmup under one login, and you're big enough that a custom quote beats stitching tools together.

FAQ

Is MailToaster free to try?

MailToaster offers a 14-day free trial with no credit card required, per mailtoaster.ai. After the trial it's a flat $29 per mailbox per month with no separate tiers.

Why doesn't Warmy show its pricing anymore?

As of 2026, warmy.io restructured its pricing page into B2B, B2C, and Custom plans with no dollar amounts listed. You have to book a demo or start the 7-day trial to get a quote.

Can I run MailToaster and Warmy on the same mailbox?

You can, but it's not worth it. Running two warmup engines against one inbox at once just doubles the automated activity Gmail and Outlook are watching for, without adding any real benefit over picking one tool.

Do I still need a warmup tool if Instantly or Smartlead already warms up my inboxes?

Only if the built-in warmup isn't cutting it. Instantly and Smartlead both include basic warmup for free, so add MailToaster or Warmy when you need the extra layer, like DNS validation or spam-placement testing, that the built-in version skips.

Warmup tools fix inbox placement. They don't fix a bad list or copy nobody replies to, which is where most cold email programs actually stall. If you'd rather have someone else run the whole outbound motion, that's what Modern Inbound does. See how the setup works.
