// Unspam vs Folderly
A Folderly alternative with previews, heatmaps and a real free tier
Folderly, by Belkins, is a managed warmup and deliverability service priced per mailbox. Unspam is a self-serve pre-send testing suite (spam score, inbox placement, client previews and AI heatmaps) from $9/mo, and it does not do warmup.
Which one fits you?
- You need automated inbox warmup. That is Folderly's core product; Unspam does not warm up inboxes at all
- You want free always-on spam-placement monitoring with Email, Slack and SMS alerts: Folderly's Pulse is $0/month
- You value hands-on, managed support: reviewers consistently praise Folderly's responsive human team

Why teams move from Folderly to Unspam.
Pricing in a different bracket
Folderly's core product is listed at $96 per mailbox/month billed yearly (third-party reviews report $120 on monthly billing), and its Inbox Insights testing add-on is $79/mo for 100 tests. Unspam's Business plan is $19/mo for 200 spam tests, 200 previews, 50 heatmaps and 50 placement tests, with a 14-day no-questions-asked refund.
Previews and heatmaps included
Folderly has no rendering previews and no heatmaps. Unspam shows how your email renders across clients and devices and overlays an AI eye-tracking heatmap, on every plan, including the free one.
Seeds beyond Gmail, Outlook and Yahoo
Folderly's placement seeds cover Gmail, Outlook and Yahoo, and reviewers note thin coverage beyond Google and Microsoft. Unspam runs placement tests across 6+ providers, including Zoho, ProtonMail and AOL, with results in about 30 seconds.
// FAQ
Unspam vs Folderly, answered.
Is Unspam a full replacement for Folderly?
Not if warmup is why you use it. Folderly's core product warms up mailboxes automatically; Unspam tests and monitors deliverability but does not warm up inboxes. If you mainly use Folderly's Inbox Insights for placement testing, Unspam covers that job, and adds client previews, heatmaps and email verification. Unspam also offers deliverability consulting as a separate service if you want hands-on help.
How does the pricing compare?
Folderly's core product is listed at $96 per mailbox/month billed yearly, with third-party sources reporting $120 on monthly billing; its Inbox Insights testing add-on is $79/mo for 100 tests. Unspam's paid plans run from $9/mo for the whole suite, with 2 months free on annual billing and a 14-day refund.
What is the biggest functional difference?
Direction. Folderly maintains sender reputation by sending automated warmup traffic from your mailboxes; Unspam checks an email before you send it: spam score, inbox placement across 6+ providers, client previews and an AI heatmap. One repairs reputation over time; the other tells you where a specific email lands.
How do the free tiers compare?
Folderly's free tiers are genuinely useful: Inbox Insights gives 2 placement tests per month, and Pulse spam-placement monitoring with Email, Slack and SMS alerts is $0/month. Unspam's free plan includes 10 spam tests, 10 previews, 10 heatmaps and 3 placement tests per month, with the AI assistant included and no card required.
