Introduction

SendLucid Documentation

SendLucid has two halves:

  • Deliverability testing — send a test email, get a 0–100 score across 25+ checks (SPF, DKIM, DMARC, BIMI, reputation, content, infrastructure), with a clear fix for everything that fails.
  • Campaign intelligence — connect your email platform and get analytics that surface what’s working, what’s hurting you, and the highest-impact actions to take next.

Start here

  • New to the concepts? Read Core Concepts — deliverability, the score, attribution, LTV, fatigue, and how SendLucid finds opportunities.
  • Want to check one thing fast? Use the free Tools — SPF, DKIM, DMARC, BIMI, blacklist, MX, and header analysis, no login required.

Coming soon

Getting Started walkthroughs and per-page guides for the dashboard and analytics suite are being written. The deliverability check reference and connecting-your-platform guides land next.
