What Unspam is
Unspam is a free email testing tool. Before you send a campaign, you can use it to check the spam score of your message and test delivery capability, so you can fix problems while they are still cheap. It runs authentication checks including SPF, DKIM, and DMARC, which are the records that tell receiving servers your mail is legitimate. On top of that it uses eye-tracking data to generate heatmaps showing which parts of an email tend to draw attention, and it provides a preview of how the message will appear. The site pitches it to email marketers, communication leads, and anyone who wants their mail to land in inboxes.

What to watch out for
A clean result is a good sign, not a guarantee: inbox placement also depends on your sending reputation, list quality, and recipient behavior, none of which a single test can measure. Heatmaps show general attention patterns rather than how your specific audience will read. The checks are a snapshot at test time, so re-test after major changes. And since the tool is free, the feature set and availability can change over time. For team use, agree on naming and editing conventions in advance to avoid version conflicts or duplicated work. Name and archive exported files consistently so you can find and reuse them, and keep a backup copy of key data.
