Send an email to the testing email address below.
Check if your domain name, email address, or IP address is blacklisted across Spamhaus, SpamCop, Barracuda, and other major lists. Catch listings before they hurt your deliverability, and keep mail flowing to every subscriber.
Check your emails against WCAG accessibility rules: color contrast, alt text, heading order, dark-mode rendering. Make sure every subscriber can read what you send, on any client or screen reader.
Copy the unique testing address generated for your session and send your email to it from the platform you actually use.
View your results to see a clear spam score, with each warning expandable to learn why it fired, authentication, content, links, and more.
See exactly how your email renders on desktop, tablet, and mobile, plus an AI heatmap of where subscribers will actually focus and an AI assistant that suggests fixes.
Run an inbox placement test across providers to confirm whether your email lands in the primary inbox, promotions, or spam.
Your spam score is a 0 to 100 rating of how likely your email is to reach the inbox instead of the spam folder. Unspam calculates it from authentication (SPF, DKIM, DMARC), sender reputation, blacklists, and content signals, then shows exactly which checks cost you points and how to win them back.
Significant issues need attention before this mail reaches the inbox reliably.
Real risk of the spam folder. Fix the flagged checks in order.
A few things worth tightening before you can fully rely on the inbox.
Strong deliverability. Keep doing what you are doing.
If core authentication fails, the report flags high risk no matter the number, because a failed SPF, DKIM, or DMARC check alone can send mail to spam.
A minor mistake, such as a typo or a broken link, can harm your credibility and reduce the effectiveness of your email communication. To address this, we've introduced an email spam checker, email deliverability tester, and a heatmap tool.
Enhance your email deliverability using our email test tool. Unspam evaluates key elements of your email, provides an email spam score, and predicts outcomes using a heatmap of your email newsletter.
Use these deliverability test insights and our spam score to refine your strategy, ensuring your emails don't just land in the inbox, but also engage your readers.
Maximize your email impact with our Inbox Placement test tool: ensure your messages bypass email spam filters, navigate promotions tabs, and land directly in your recipient's primary inbox every time.
Test the email deliverability and optimize for prime delivery on Gmail, Outlook, Yahoo, and more email platforms.
Create more impactful campaigns and get better results with accurate data on where subscribers are looking and how they're reading your emails.
See exactly how your email renders on real email clients and real devices before you send. Unspam previews your message across 50+ clients and devices, from Gmail and Outlook to Apple Mail, iPhone, and Android, in both light and dark mode.
Catch a broken layout, an invisible dark-mode logo, or a cut-off button while you can still fix it, so every recipient sees your email exactly the way you designed it.
Schedule a test once. Unspam runs it on your selected days, tracks your spam rate across inbox providers, and alerts you as soon as your placement starts to slip.
Pick the email, pick the days, and Unspam handles the sending. Every execution is stored. Every spam rate is graphed. When the number climbs, an email alert lands in your inbox before customer complaints do.
Helping the world's best marketing teams maintain good sender reputation and email deliverability rates.
