Email deliverability and spam testing

Unspam.email is an email deliverability testing tool focused on finding spam triggers before a campaign is sent. It combines spam scoring, inbox placement tests, email previews, heatmaps, and authentication checks so senders can inspect both message content and technical setup.

The homepage positions the product as a way to check whether a newsletter or transactional email is likely to land in the inbox, promotions tab, or spam folder. It also includes separate browser-based tools for SPF, DMARC, and DKIM record lookup, plus related checks such as BIMI and reverse DNS guidance.

Core capabilities

Email spam scoring

Send a message to a unique session address and get a spam score that highlights deliverability signals such as authentication, content, links, and blacklists.

Inbox placement testing

Run inbox placement tests across multiple providers to see whether messages land in Inbox, Promotions, Spam, or Missing.

Email preview and heatmaps

Preview how an email renders on desktop, laptop, and mobile, with an AI heatmap that indicates where attention is likely to go.

Authentication and DNS checks

Check SPF, DMARC, DKIM, BIMI, reverse DNS, and related email health signals from the product hub.

Accessibility testing

FAQ

Is there a free plan?

Yes. The free plan includes monthly allowances for spam tests, email previews, heatmaps, and inbox placements, along with the AI assistant, and the pricing page says no credit card is required.

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

A spam test scores a single message against deliverability signals such as authentication, content, and blacklists before you send it. An inbox placement test sends to a seed list across providers and reports where the message landed, such as Inbox, Promotions, Spam, or Missing.

How does the workflow work?

You send an email to a unique testing address for your session, then the product returns a spam score, email preview, heatmap, and inbox placement results. The SPF, DMARC, and DKIM tools can also be used directly in the browser to inspect DNS records.

Can I automate repeated checks?

The homepage says spam test results are available about 30 seconds after the email is received, and the pricing page describes historical results and Autopilot scheduling on paid plans.

Is any data stored when I use the checker tools?

The site’s standalone record checkers run in the browser over DNS-over-HTTPS with no signup and nothing stored. The homepage also emphasizes that a unique testing address is generated for each session.
