How it works

One test address, one useful scorecard.

SpamLens is designed for fast pre-send checks. Your team sends the exact message it plans to send, then reads a report built for both business and technical users.

  1. Get a unique test email addressGenerate an address like test-abc123@in.spamlens.eu for the message you want to test.
  2. Send your emailUse your campaign tool, SaaS product or transactional email provider.
  3. Read the scorecardSee what is ready, what is contested, and what gets blocked before digging through cryptic headers.
Five judges

Each judge gives your email a score out of 10.

Authentication, deliverability, content, structure and trust are scored separately, so the next fix is obvious.
