How much does Warmup Inbox cost in 2026?

Warmup Inbox has three published tiers: Basic at $15/inbox/mo ($180 billed yearly, 75 warmup messages/day), Pro at $49/inbox/mo ($588 billed yearly, 250 messages/day, "Best Value" label), and Max at $79/inbox/mo ($948 billed yearly, 1,000 messages/day), per Warmup Inbox's pricing page. Agencies running 15+ inboxes get custom pricing, with further volume discounts past 50 inboxes.

Every tier includes a 7-day free trial with no credit card required, per Warmup Inbox's site. That's the single biggest difference from Warmy: you can see the exact monthly cost before you sign up for anything.

How much does Warmy cost in 2026?

Warmy does not list dollar amounts anywhere on its pricing page. Instead it offers three categories, B2B Sender, B2C Sender, and Custom, all priced on "volume-based pricing" tied to your warmup email volume, per Warmy's pricing page. You have to book a demo to get an actual number.

The honest take: gated pricing is a red flag for a self-serve tool, and the industry won't say it out loud. If a 2-person agency just wants to warm up 5 inboxes this week, calling sales for a quote is friction Warmup Inbox doesn't force you through.

Which warmup tool has better deliverability monitoring?

Warmup Inbox runs 24/7 monitoring across 100+ blacklists with automatic rescue protocols and built-in SPF/DKIM/DNS checks, claiming 98% Primary inbox placement within 30 days, per Warmup Inbox's site. Warmy leans on Google Postmaster Tools data plus a placement test and a human deliverability expert reviewing your account on the Custom plan, per Warmy's site.

If you want automated, always-on monitoring with hard numbers, Warmup Inbox's dashboard gives you that without paying for a human reviewer. If you'd rather have an actual person looking at your Postmaster data, Warmy's expert-review angle is the differentiator, but it's only confirmed on the higher-touch Custom tier.

Contract terms and best-fit team size

Both tools bill month-to-month with a 20% annual discount on Warmup Inbox (Warmy's annual terms aren't published), and both let you cancel anytime, per each tool's site. Warmup Inbox targets marketers, SDR teams, agencies, and recruiters running cold outbound at scale. Warmy markets separate products for agencies, SDR teams, growth teams, and an iGaming vertical, claiming 35,000+ users and 650,000+ domains improved, per Warmy's homepage.

For a lean team sending under 15 inboxes, Warmup Inbox's published tiers make budgeting simple. For a larger B2B sender juggling multiple domains who wants white-glove support, Warmy's Custom tier is built for that, once you get a quote.

FAQ

Is Warmup Inbox or Warmy cheaper?

Warmup Inbox is the only one of the two with a published price: $15/inbox/mo on the Basic tier, per Warmup Inbox's pricing page. Warmy's pricing is custom and volume-based, so there's no public number to compare against, per Warmy's pricing page.

Do Warmup Inbox and Warmy both offer free trials?

Yes. Both offer a 7-day free trial with no credit card required, per each tool's site. That's identical across both platforms.

Which tool is better for a small agency running under 15 inboxes?

Warmup Inbox, mainly because you can see exact per-inbox pricing on the Basic and Pro tiers without booking a call. Warmy's Custom-tier structure is built around larger volume conversations, per Warmy's pricing page.

Does either tool guarantee inbox placement?

Neither guarantees placement, since inbox placement depends on your domain history, content, and sending patterns too. Warmup Inbox cites a 98% Primary placement rate within 30 days as an internal benchmark, per Warmup Inbox's site, while Warmy focuses on Postmaster-driven monitoring rather than a stated placement percentage.

Warmup tools only fix half the deliverability problem. The other half is the list you're sending to and the copy you're sending with, which is where most cold email programs actually break. If you'd rather have a team handle infrastructure, data, and copy end to end instead of managing another dashboard, that's what Modern Inbound's setup service does.
