What is Unspam?

Unspam is an email deliverability testing platform with a free spam checker, inbox placement tests, email previews across 50+ clients, AI eye-tracking heatmaps, and an AI assistant that recommends fixes. Send your email to a unique test address, review authentication and content warnings, preview rendering, and confirm inbox placement across Gmail, Outlook, Yahoo, and other providers before you hit send.

How to use Unspam?

1. Copy the unique testing email address shown on the homepage. 2. Send your campaign from the platform you actually use to that address. 3. Click View Results to see your spam score, expandable warnings, previews, and AI recommendations. 4. Run an inbox placement test to confirm whether messages land in Inbox, Promotions, or Spam.

Unspam Core Features

Email Spam Checker

Scores a single message against deliverability signals including SPF, DKIM, DMARC authentication, content, blacklists, and HTML before you send.

Inbox Placement Test

Sends your campaign to a seed list across Gmail, Outlook, Yahoo and more, then reports where each copy landed: Inbox, Promotions, Spam, or Missing.

Email Preview

Renders your email on 50+ real email clients and devices in light and dark mode so you catch broken layouts before subscribers do.

AI Eye-Tracking Heatmap

Predicts where readers look first on desktop, tablet, and mobile so you can place offers and CTAs in high-attention zones.

AI Assistant

Reads your test results and tells you exactly what to fix, from authentication and content to specific lines hurting deliverability.

Blacklist Monitoring

Checks whether your domain, email address, or IP is listed on Spamhaus, SpamCop, Barracuda, and other major blacklists.

Unspam Use Cases

Spam-test every newsletter before sending to your subscriber list

Verify inbox placement across Gmail, Outlook, and Yahoo before a product launch email

Preview campaign rendering on mobile and desktop clients in light and dark mode

Catch domain or IP blacklist listings before they hurt deliverability

Unspam Frequently Asked Questions

How do I run an email spam test?

Send your email to the unique testing address shown at the top of the homepage, then click View Results. Each user gets a private test address so only you can see the results.

Can I use Unspam for free?

Yes. Create an account and you get a monthly allowance of spam tests, email previews, heatmaps, and inbox-placement tests at zero cost with no credit card required. Limits are listed on the pricing page.

What's the difference between a spam test and an inbox placement test?

A spam test scores one message against deliverability signals before you send. An inbox placement test sends your campaign to a seed list across major providers and reports where each copy actually landed.

Do unused tests roll over to the next month?

No. Monthly quotas reset on your billing anniversary. If you regularly hit the ceiling, upgrading to the next tier is usually cheaper than buying overage.

Do you offer a money-back guarantee?

Yes. Paid plans include a 14-day no-questions-asked refund window. Reach out from the support chat and refunds are processed the same day.
