What it does when it runs

Always-on spam and deliverability guardrails for cold email copy. Apply these rules whenever writing, reviewing, or QA-ing subject lines, openers, follow-ups, CTAs, or any cold outreach copy. Trigger on phrases like "check this for spam", "spam word check", "deliverability review", "QA this copy", "flag banned words", "check subject line", "is this safe to send", "scan for spam triggers", or any time cold email copy is being generated or reviewed. Also trigger automatically as a background rule whenever the campaign-copywriting or cold-email-copywriting skill is active -- these guardrails apply to EVERY piece of outbound copy generated, even if the user does not explicitly ask for a check.

Spam Word Checker

Always-on spam and deliverability rules. Apply to every subject line, opener, second line, follow-up, and CTA generated or reviewed.

When These Rules Apply

Subject lines, openers, second lines, follow-ups, CTAs
Any cold outreach copy being written or QA'd
If a deliverability checker or review flags a word/phrase, treat it as banned going forward unless user explicitly approves an exception
When in doubt, choose the lower-hype rewrite

Banned Single Words

Do not use any of the following standalone or as part of a compound word/phrase:

get, bank, credit, access, open, compare, problem, now, billing, deal, finance, financial, claims, insurance, mortgage, soon, new, performance, freedom, home, sales, medical, urgent, life, marketing, investment, diagnostics, friend, cash, invoice, extra, purchase

Nuance: Punctuation, hyphens, or splits do not make a banned token safe. Treat close variants as banned when the root token is still obvious:

cash-cycle → still cash → banned
invoice-line → still invoice → banned
extra-room → still extra → banned
purchase-cycle → still purchase → banned

Banned Short Phrases

off chance, one time, all good, following up here, last note from me here, great fit, bumping this once, just following up once, circle back, one more quick follow-up, keep this open, compare notes, compare notes live, appreciate the reply

Formatting & Style Bans

No em dashes
No ALL CAPS
No multiple exclamation marks
No greeting prefix before first name (no Hi, Hello, Hey)
No third-person company references ([Company] offers, [Company] helps)
No fake urgency, misleading subject lines, excessive links, or promotional formatting

Unsubscribe / Closeout Line Rules

Never write an unsubscribe line that promises to stop following up based on silence. We DO follow up — that's the whole point of sequences. Silence-based promises are misleading and fail to match actual behavior.

Banned patterns (silence = we stop):

I will take silence as a no
read no reply as a pass
assume no response means no interest
If I don't hear back, I will leave it there / let this one go / leave you alone
I am happy to stay out of the way (if implied by context)
Any construction where the user doing nothing = we stop sending

Allowed patterns (explicit user action = we stop):

A reply of 'no' / 'not for us' / 'pass' is enough and I'll step out of your inbox (action-conditional)
Just say the word and I'll stop (asks for action)
A one-word reply works fine if you'd rather I stopped (asks for action)
Feel free to ignore this (permission, no promise)
Happy to try back later when timing makes more sense (defers, doesn't stop)
If this isn't the right angle, tell me what is (invites pivot)
If I misjudged the fit, I'd rather know than guess (asks for clarification)

Rule of thumb: the user has to do something explicit for the sequence to stop. Silence keeps the cadence running.

Safe Replacement Patterns

Banned / Risky	Safe Replacement
`free consultation`	`open to a short conversation`
`special offer`	`what we're seeing in the market`
`act now`	`if relevant, happy to send details`
`guaranteed results`	`this may be relevant depending on your situation`
`click here`	`let me know and I can send it over`
`limited time`	`not sure if this is timely for you`
`increase revenue`	precise business outcome (e.g. `help support liquidity`)

Rewriting Logic

Rewrite hype into plain, observational language
Replace pressure with permission
Replace promotional wording with specific business language
If a line sounds like an ad, coupon, scam, or phishing message → rewrite it
If a bump sounds filler-heavy or vague → replace with a direct next-step question or clear closeout line
If a value line uses fuzzy wording (tight, fit, access, problem) → rewrite so the operational meaning is explicit
If a reply acknowledgement sounds low-status → remove it and go straight to the next useful question
If a sentence sounds AI-polished → simplify until it reads like a person speaking plainly

Company Name Handling

If a banned word appears inside a company name used in copy:

Do not drop the company reference entirely if the name is still needed
Rewrite the displayed name so the banned token is removed from standalone form
Priority: remove the token if the remaining name still reads clearly; only abbreviate or compress when needed

Examples:

Access Brand Communications → AB Communications
Calcon Mutual Mortgage → Calcon Mutual
Buckeye Insurance → Buckeye
Coming Soon New York → Coming NY

Final QA Checklist

Before approving any copy:

Scan subject line for spam-trigger wording
Scan body for banned or high-risk wording
Rewrite any hype-heavy or pressure-heavy line into plain language
Remove fake urgency
Confirm email sounds like a credible real person, not a promotion

What to do next

If flags cleared: run /smartlead-spintax before upload, then launch via /smartlead-campaign-upload-public.

If flags fired: back to /campaign-copywriting to rewrite the flagged lines. Re-run this check after.

Or wait: this skill auto-triggers on every copy draft — there's no standalone "next". Continue whatever copy work you were doing.
