- You want to know where a campaign lands before you hit send: seed-list placement across Gmail, Outlook, Yahoo, Zoho, ProtonMail, AOL and GMX, with results in about 30 seconds.
- You need client previews across 50+ clients and devices, in light and dark mode. Warmy offers none.
- You'd rather start free than with a trial: a free plan with no card, paid from $5/mo against Warmy's $49/mo starting price, and a 14-day no-questions refund.
- You're a small team or agency that needs testing, not warmup: $0.18 a spam test and $0.50 an inbox placement, from a $5 monthly minimum, without paying for warmup volume you won't use
A Warmy alternative with spam testing, inbox placement and client previews
Warmy is an AI-driven platform built around automated inbox warmup. Unspam doesn't warm inboxes. It tests them: spam score with authentication and blacklist checks, seed-list inbox placement at 7 providers and client previews in one plan, free to start.
Compared from public pricing and product pages, October 2026.
Which one fits you?
- You need automated inbox warmup. It is Warmy's core product, and Unspam doesn't warm inboxes at all.
- You want continuous DNS record-status monitoring on a dashboard, across SPF, DKIM and DMARC. Unspam checks all three per test, and its DMARC monitoring reads aggregate reports and tracks the published policy rather than watching every record.
- You're warming many mailboxes and want weekly auto-run deliverability tests, blacklist alerts and list validation bundled with the warmup.
Why teams move from Warmy to Unspam.
Start free, not at $49
Warmy's plans start at $49/mo, priced by the volume of warmup email they generate, and its free option is a 7-day trial. Unspam has a free plan that renews every month with no card, and paid testing starts from a $5 monthly minimum with a 14-day refund.
Pay for tests, not for warmup volume
Cost is the most common complaint about Warmy: 54 of roughly 498 G2 reviewers flag it as expensive. Its plans bill for warmup volume from $49/mo, whether or not you need warmup at all. Unspam charges only for the tests you run, from a $5 monthly minimum at $0.18 a spam test, however many mailboxes you send from.
See how the email looks, not just where it lands
Warmy has no client previews. Unspam renders your email across 50+ clients and devices, in light and dark mode, on every plan (including the free one) alongside spam scoring and placement tests, so you catch a broken render or an unreadable dark-mode version before you warm a single inbox.

What each one costs.
Warmy's pricing page shows two self-serve plans, B2B Sender and B2C Sender, each listed as starting from $49/mo with volume-based pricing: you pay for the volume of warmup email Warmy generates. A Custom plan is designed with its team. The self-serve plans start with a 7-day free trial and no card. The page does not publish the higher volume tiers, so prices above the entry point come from Warmy.

Unspam vs Warmy, answered.
Is Unspam a full replacement for Warmy?
No. Warmy's core product is automated inbox warmup, and Unspam doesn't warm inboxes. Unspam covers the testing side (spam scoring, inbox placement, client previews and blacklist checks), so it can replace Warmy's testing features, not its warmup.
How does Unspam's pricing compare to Warmy's?
Warmy's plans start at $49/mo and are volume-based: you pay for the amount of warmup email Warmy generates, and a Custom plan is quoted by its team. Unspam's paid pricing starts at a $5 monthly minimum, charged per test, with a free tier, 15% off annual billing and a 14-day refund. Warmup volume and per-test pricing grow with different things, and how per-mailbox, credit and add-on pricing compare shows where that matters.
What's the biggest functional difference between Unspam and Warmy?
Warmup versus testing. Warmy sends automated engagement traffic from a mailbox network to build sender reputation. Unspam tests what happens when you send: spam score, placement across 7 providers and client previews, with results in about 30 seconds. The two approaches can complement each other.
Does Warmy have a free plan like Unspam's?
No permanent free plan: Warmy offers a 7-day trial with no card and some free standalone tools. Unspam's free plan renews every month: 5 spam tests, 3 inbox placements, 3 device previews, 5 screenshots and 5 heatmaps, AI assistant included, no card required.
