Tips for better spam score checker results
One primary CTA
Fewer links and one clear next step usually outperform a footer full of badges.
Write like a human
Specific proof beats “100% guaranteed” and “limited time” on every channel.
Never fake Re: or Fwd:
It is a trust and phishing signal — and an easy filter feature.
Pair with subject testing
Use the Subject Line Tester for open-rate heuristics, then re-check full body spam risk here.
How to use Spam Score Checker
A short path from input to something you can ship or test.
Paste subject and body
Optional from name. Plain text or full HTML source both work.
Read dual scores + pillars
Risk index (0–100), SA-like (0–10), and which pillars are driving risk.
Work the priority fix list
Each fired rule includes a concrete rewrite. Start with critical/high rules.
Seed-test authentication + placement
This engine is content-only. Still verify SPF/DKIM/DMARC and send to seed inboxes.
Why teams use Spam Score Checker
Multi-rule, not a single keyword dump
Independent rules for urgency, financial hype, phishing, HTML scripts, image-only layouts, shorteners, IP URLs, and more.
Smart stacking
Combo bonuses when caps + !! or shorteners + spam language co-occur — the patterns that spike real-world risk.
Ham credits for good copy
Natural length, calm punctuation, unsub language, and clean links reduce the score instead of only punishing mistakes.
Private and local
Runs in your browser. No mailbox connection. Content-only — auth/DNS still need your ESP and DNS setup.
Spammy copy never gets a chance to convert. Score it like a rules engine.
Professional spam checks (SpamAssassin-style engines, Mail-Tester content layers, commercial spam-word tools) stack many small signals — not one keyword list. LoudScale’s free spam engine fires symbolic rules across lexicon, subject, formatting, links, HTML quality, phishing cues, and compliance, then applies combo multipliers and ham credits so you see risk the way filters accumulate it.
- 0–100 risk index + SpamAssassin-like 0–10 score
- Subject phrases weighted ~2.4× vs body (industry pattern)
- Pillar breakdown, rule IDs, and prioritized rewrites
Copy is one layer — deliverability is a system.
LoudScale builds lifecycle email, CRM workflows, and measurement so list health, authentication, and creative work together.

about Spam Score Checker
Clear answers on access, quality, and how this free tool fits a real workflow.

No. It is a heuristic pre-send check based on common spam patterns. Gmail, Outlook, and ESPs use proprietary models, authentication (SPF/DKIM/DMARC), reputation, and engagement history.
Risk index is 0–100 (higher = worse content risk). The SA-like score is a 0–10 scale similar to how SpamAssassin-style totals are read — many servers treat ~5.0+ as spam. Neither replaces your ESP’s live filter.
Scoring runs in your browser. Drafts autosave locally. Export may require suite unlock, but content is not sent to an AI model for this tool.
Yes. Paste HTML source; the engine checks scripts, forms, image-only balance, text/html ratio, fonts/colors, links, and the stripped text lexicon. For pixel-perfect rendering, use your ESP preview.
SPF, DKIM, DMARC, and blacklists require DNS and a real message path. This tool focuses on the content layer you can fix before send — then validate auth and placement with Mail-Tester-style sends or GlockApps-class seed tests.
