What is Email Spam Word Checker?
Before send, you want a quick scan for classic spam-trigger phrases. ToolYour Email Spam Word Checker matches subject/body text against a fixed lexicon, counts hits, and returns a heuristic score. It is not Gmail/Outlook filtering, DMARC, or a full content reputation system. Same route via REST and MCP (POST /api/v1/marketing-apis/email-spam-word-checker).
What are common questions about Email Spam Word Checker?
Is a clean score “inbox guaranteed”?
No. Deliverability depends on reputation, authentication (SPF/DKIM/DMARC), list quality, and engagement. Use Security Tools for DNS auth checks.
What text can I paste?
Subject, plain body, or HTML — the checker lowercases and scans for lexicon tokens.
Does this check attachments or images?
No — it scans the text you paste (subject, plain body, or HTML). Image-based spam signals and attachments are out of scope.
What are the key features of Email Spam Word Checker?
Lexicon hit list
Each matched phrase with occurrence count for rewrite focus.
Heuristic score
Simple 0–100 for triage across drafts.
How do you use Email Spam Word Checker?
Paste subject or body
Include the parts recipients actually see.
Rewrite hit phrases
Prefer specific value over “FREE!!! / act now” patterns.
Why this tool exists
Certain words and phrases ('FREE!!!', 'act now', 'guaranteed') correlate with spam filtering even though no single word guarantees a block. Email Spam Word Checker exists as a fast, deterministic pre-flight scan against a fixed lexicon — a first pass before you worry about authentication and reputation.
Problems it solves
Writers rarely notice their own spam-trigger phrasing because it reads naturally to them; a lexicon scan catches it objectively. Running this before send is faster than waiting for deliverability data to show up as a drop in open rates days later.
Common use cases
- Agency pre-send review: scanning a client's subject and body copy for classic trigger phrases before scheduling a send.
- In-house marketer: checking a promotional email with discount language ('free', '% off', 'limited time') for stacked spam tokens.
- Pre-launch: running a new welcome or nurture sequence through the checker once, before it goes live for all new subscribers.
- Agent/MCP: an agent flagging high-risk phrasing in generated email drafts before a human copywriter finalizes them.
Honest scope
A fixed word list cannot catch novel spam patterns, image-based spam signals, or sender reputation issues — it is not Gmail/Outlook filtering, not DMARC/SPF/DKIM authentication, and not a content reputation system. Treat a clean score as one pre-flight checklist item, not a deliverability guarantee. Use Security Tools for DNS authentication checks.
