Frequently Asked Questions

How to run a mail test, what the report covers, and how to raise a low deliverability score.

You get a unique test address. Send one message to it from your app, SMTP server, or mail client. The report scores SPF, DKIM, DMARC, spam rules, DNS, content, and blacklist status.

Yes. You can run one test at a time at no cost, with no signup required. Use it before a campaign or after a DNS change to see what receiving servers will see.

The report covers your spam score and triggered rules, authentication results, MX and reverse DNS, major blacklist listings, and the plaintext, HTML, and headers from the message you sent.

Publish aligned SPF, DKIM, and DMARC records, remove spammy phrasing or broken HTML, and check that your sending IP is not listed. Then send another test. Our SPF and DMARC generators can help with the DNS side.
