VERDICT

Should I use Unspam?

Run a free spam test and get your spam score in 30 seconds. Check SPF, DKIM, DMARC, and blacklists with a full email deliverability test, before you send. - unspam.email

Worth it. Buy if you send email campaigns and want a fast, cheap deliverability check — the free 30-second test makes trying it risk-free. Skip it if you need continuous DMARC monitoring or enterprise vendor guarantees.

Gotchas - check before you buy

medium

Free tests cover entry use; recurring senders hit pay-per-test fees — model your monthly volume first

medium

Five pricing tiers per G2, but the public feature split between plans is opaque

medium

No external funding on record — likely bootstrapped; thin bench if you need vendor support guarantees

medium

No public security page; ask how test email content and headers are stored first

Pros and cons

Pros

  • Free spam test returns a spam score in 30 seconds
  • Tests SPF, DKIM, DMARC, and blacklists in one run

Cons

  • No dedicated security page found on its site
  • Some G2 users cite difficulties; snippet truncated in source
  • Guess: one-off tests don't monitor; deliverability drifts between checks
