- 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 and AI eye-tracking heatmaps. Warmy offers neither.
- You'd rather see prices than request a quote: free tier with no card, paid from $5/mo, and a 14-day no-questions refund.
- You're a small team or agency that would rather pay for tests than for mailboxes: $0.18 a spam test and $0.50 an inbox placement, from a $5 monthly minimum, with no per-mailbox maths
A Warmy alternative with spam testing, previews and AI heatmaps
Warmy is an AI-driven platform built around automated inbox warmup. Unspam doesn't warm inboxes. It tests them: spam score, seed-list inbox placement, client previews and AI heatmaps in one plan, free to start.
Compared from public pricing and product pages, September 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.
Pricing you can read
As of mid-2026, Warmy's pricing page shows no numbers: plans are quote-based, and one reviewer notes 'you have to sign up to see the plans'. Its entry tier was previously listed at $49/mo per mailbox. Unspam's pricing is public: a free plan with no card, paid from $5/mo, 14-day refund.
Pay per test, not per mailbox
Cost is the most common complaint about Warmy: 54 of roughly 498 G2 reviewers flag it as expensive, and per-mailbox pricing grows with every inbox you add: five inboxes have been cited at around $245/mo. Unspam charges for tests rather than mailboxes, 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 and no heatmaps. Unspam includes device previews and AI eye-tracking heatmaps on every plan (including the free one) alongside spam scoring and placement tests, so you catch a broken render or a buried call to action before you warm a single inbox.

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 AI heatmaps), so it can replace Warmy's testing features, not its warmup.
How does Unspam's pricing compare to Warmy's?
Warmy's pricing is quote-based as of mid-2026; its entry plan was previously listed at $49/mo per mailbox, and pricing is effectively per inbox. 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. Per-mailbox billing multiplies with team size, and how per-mailbox, credit and add-on pricing compare is where that shows up against paying per test.
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, previews and heatmaps, 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.
