Warmy.io Pricing in 2026: What Every Plan Actually Costs (And What They Won’t Tell You)

You visited Warmy.io’s website to check pricing. You got a “Book a Demo” button. So now you’re here. That frustration is by design — Warmy.io removed public pricing from their website and pushed all prospective buyers through a sales call to get actual numbers. As of May 2026, their pricing page doesn’t even show the old tier names — just three categories (B2B sender, B2C sender, Custom) with “Book a demo” on each.

You’re not alone. This is the #1 complaint in cold email communities: “What does Warmy actually cost? Their site doesn’t show it.” One r/coldemail user put it bluntly: “I calculated that warming 20 mailboxes on Warmy would cost ~$1,000/month. For a background process. That’s insane.”

This guide gives you what Warmy.io won’t: a verified breakdown of every plan’s pricing, an honest analysis of what’s gated behind each paywall, total cost projections at 5 to 100 mailboxes, and a clear framework for deciding whether Warmy’s price is justified for your situation, or whether a smarter alternative exists.

Note: If you want to check your current deliverability before spending a dollar on warmup, run a free spam test first. It takes 2 minutes and shows exactly where your emails land.

Warmy.io Pricing at a Glance (2026)

Important caveat: The pricing below is sourced from G2 user submissions, Capterra reviews, and cached historical data. Warmy.io no longer publishes pricing publicly. These figures represent the most comprehensive available breakdown, but pricing may have changed. Always verify directly with Warmy.io.

UPDATE — Live pricing page verified (May 2026): Warmy.io’s official pricing page (warmy.io/pricing) has been completely restructured. The old 5-tier model (Starter through Platinum) is no longer displayed. 

Instead, Warmy now shows three categories: “B2B sender,” “B2C sender,” and “Custom plan”, all requiring “Book a demo” with no prices visible. All three categories now advertise: volume-based pricing, Google Postmaster integration, deliverability monitor, and a dedicated deliverability expert. 

The historical per-mailbox prices below remain the best available third-party data, but the tier structure itself may no longer apply. Warmy also now claims 35,000+ happy businesses and 650,000+ domains improved.

A few things stand out immediately. First, there’s no unlimited mailbox option, every mailbox is priced separately. Second, there are no publicly visible volume discounts. And third, the jump from Starter ($49) to Premium ($189) is nearly 4x the price. We’ll come back to whether that gap is justified.

Warmy.io does reportedly offer a 7-day free trial based on user reports, but availability may vary. Annual billing provides approximately 2 months free (~16–17% off), bringing monthly costs down to roughly: Starter ~$41, Business ~$108, Premium ~$158, Expert ~$233 (SaaSWorthy, Lemwarm review).

For context: approximately 45% of SaaS companies publicly display pricing, while 55% do not (Vena Solutions, citing OpenView data). Warmy’s decision to hide pricing goes against the buyer-preference trend toward self-service evaluation, and it’s the single biggest friction point in community discussions.

Warmy.io Plan-by-Plan Breakdown: What You Actually Get

Starter Plan (~$49/mailbox/month)

The entry-level plan covers the basics: up to around 100 warmup emails per day, Adeline AI for automatic volume adjustment, and standard deliverability metrics. It includes 1 DNS record test and 1 inbox placement test per period.

What it does not include: template warmup, industry/language targeting, or access to a dedicated deliverability expert. (Note: Warmy’s current pricing page now lists “dedicated deliverability expert” for all plan categories, suggesting this may no longer be gated.) For most SDRs and B2B founders warming a handful of mailboxes, the Starter plan is the realistic option.

Honest verdict: Gets the job done for basic volume warmup. But users on G2 consistently report feeling limited.

Business Plan (~$129/mailbox/month)

The Business plan bumps warmup volume to around 300 emails per day and unlocks additional deliverability metrics. It includes 3 DNS record tests and 3 inbox placement tests, plus custom pacing and language selection. Based on user reports, template warmup remains gated at this tier.

At $129/mailbox, you’re paying 2.6x the Starter price for more volume and slightly more visibility, but still without the headline features Warmy uses to justify its premium tiers.

Honest verdict: Hard to justify for B2B cold outreach at this price point.

Premium Plan (~$189/mailbox/month)

This is the tier where Warmy’s marquee features unlock: template warmup (warming using your own email templates), industry and language targeting for warmup content, Google Postmaster integration, and a dedicated deliverability expert.

Here’s the thing: these are the features that sound impressive on a pricing page but don’t actually improve deliverability.

Template warmup is counterproductive. Warmup emails should be 100% harmless: neutral content with no tracking pixels, no commercial links, no aggressive copy. If you warm up using your actual campaign templates, you’re training spam filters to associate your sending domain with the risky elements in those templates.

Industry and language warmup are cosmetic. Google and Microsoft don’t factor “what industry your warmup emails discuss” into sender reputation decisions. These signals don’t exist in their filtering models.

The math: You’re paying ~$140/mailbox/month more than the Starter plan ($189 vs $49) for features that look good on paper but don’t move the inbox placement needle.

“Signed up expecting full warmup customization but realized topic selection, language targeting, and template warmup were all locked behind Premium or higher tier.” — G2

Expert Plan (~$279/mailbox/month)

The Expert plan pushes warmup volume to approximately 2,000 emails per day and includes all Premium features plus 50 DNS record tests, 50 inbox placement tests, agency dashboard access, and priority support. This is Warmy’s second-highest tier, targeted at organizations with heavy volume requirements or agency support needs.

At $279/mailbox, this plan only makes economic sense for users warming a very small number of mailboxes with specific high-volume requirements, or agencies and enterprise buyers for whom white-glove support justifies the premium.

Honest verdict: For B2B cold outreach, 2,000 warmup emails/day per mailbox is far beyond what most teams need. And at $279/mailbox, 10 inboxes cost $2,790/month.

Platinum Plan (~$429/mailbox/month)

The Platinum plan is Warmy’s top-tier offering, providing up to 5,000 warmup emails per day, 100 DNS record tests, 100 inbox placement tests, and the complete feature set. This is designed for high-volume enterprise senders who need maximum warmup capacity and comprehensive testing.

At $429/mailbox, even 5 inboxes cost $2,145/month. For most B2B outreach teams, this tier represents significant overinvestment in warmup capability.

The Real Cost of Warmy.io at Scale: 5, 10, 20, 50, and 100 Mailboxes

Per-mailbox pricing sounds manageable until you multiply it across your actual infrastructure. Here’s what Warmy.io actually costs at typical B2B team sizes, compared to MailReach’s sliding-scale pricing (which decreases per mailbox as you add more).

*MailReach pricing at 100+ mailboxes via custom/agency pricing. MailReach annual billing saves an additional 20%.

Every MailReach warmup plan includes 20 free spam test credits. Warmy.io does include inbox placement tests, but the number is limited by tier (1 test on Starter, 3 on Business, up to 100 on Platinum).

The number that matters: At 50 mailboxes, a B2B team using Warmy.io’s Starter plan pays roughly $2,450/month. The same 50 mailboxes on MailReach cost approximately $900/month, including spam testing credits. That’s approximately $18,600/year in savings.

What Real Users Say About Warmy.io Pricing

Across G2, Capterra, and community forums, five consistent themes emerge.

Theme 1: Pricing Adds Up Fast

“Adds up fast when you’re running 10–15 sender accounts. I had to get on a call just to find out pricing, which already felt off.” — G2

Theme 2: Good Features Behind a Paywall

Template warmup, language targeting, and dedicated expert access all require Premium ($189+) or Expert ($279). The honest editorial note: these features don’t actually improve deliverability. The more important question isn’t “why are they gated?” — it’s “should I pay more for features that don’t work?”

Theme 3: Results Took 3–4 Weeks

Multiple reviewers praise the 5-minute setup, but note meaningful deliverability improvement took 3–4 weeks. To be fair, this is true of all warmup tools — MailReach recommends a minimum 14-day initial warmup phase too.

Theme 4: SMTP Quality Is Inconsistent

“Works great with Google Workspace but when I connected my custom SMTP, the results were mediocre at best.” — G2

Theme 5: Support Is Fine for Basics, Thin for Technical

Users on lower plans report template responses for complex questions. Dedicated expert access is gated at Premium ($189+).

The Contrarian Take: Why “Cheap Warmup” Actually Costs More

There’s a conventional conclusion many readers reach after seeing Warmy’s pricing: just find the cheapest warmup tool. Same result, lower cost. This is the wrong takeaway.

Cheap warmup tools typically build their networks from the cheapest available mailboxes: custom SMTP accounts, bulk-provisioned inboxes, disposable domains. These interactions produce engagement signals that Google and Microsoft largely ignore for B2B sender reputation.

Consider the broader context: the average global inbox placement rate is approximately 83.5%, meaning roughly 1 in 6 legitimate emails never reaches the inbox (Validity, 2025 Email Deliverability Benchmark Report). Email marketing generates an average of $36 for every $1 spent (Litmus, State of Email ROI research). Even modest inbox placement improvement from better warmup generates outsized returns.

The nuanced conclusion: The answer isn’t “pay more” — it’s “pay for what actually matters.” Network quality is the single most important factor. This is where MailReach threads the needle: premium network quality (30K+ real professional inboxes, average reputation score 95.17/100) at a mid-range price point.

When Warmy.io’s Pricing Makes Sense — And When It Doesn’t

Warmy.io Might Make Sense If:

• You need B2C email warmup. Warmy supports B2C warming and now explicitly offers a separate “B2C sender” plan category on their pricing page, which most B2B-focused tools including MailReach don’t.
• You need very high warmup volume (1,000–5,000 emails/day per mailbox) and can justify $189–$429/month.
• You’re warming 1–3 mailboxes and want an all-in-one warmup and monitoring solution regardless of cost.

Warmy.io Probably Doesn’t Make Sense If:

• You’re running B2B cold outreach. The network composition matters enormously.
• You’re warming 10+ mailboxes. Cost scales linearly with no visible volume discounts.
• You’re an agency managing client inboxes at scale.
• You need unlimited or frequent spam testing. MailReach includes 20 spam test credits plus 3 free tests per day. Warmy includes limited tests (1–100 depending on tier).
• Your company requires visible pricing for procurement.

One more thing nobody else addresses directly:

Email warmup is NOT a one-time setup cost. Warmup must run continuously, before campaigns (minimum 14 days for new domains), during campaigns, and between campaigns. Budget for warmup as an ongoing monthly expense for every active sending mailbox.
