Act now“Act now” is a classic false-urgency phrase that pressures the reader to move before they think — a hallmark of promotions and scams, so spam filters treat it as a negative content signal. It's higher-risk than most single words because urgency language is one of the patterns filters and trained recipients flag most reliably.Apply now"Apply now" is a high-pressure call-to-action that pushes the reader to act before they evaluate the offer, so spam filters treat it as a weak negative content signal. It nudges your risk score rather than blocking anything outright — on a well-authenticated, well-regarded domain a single "apply now" rarely decides whether a message reaches the inbox.Expires today"Expires today" is a false-urgency phrase that pressures the reader to act before they think, so spam filters treat it as a negative content signal — it shows up far more in promotions and scams than in normal 1:1 email. It's a weighted signal, not an automatic block: authentication and sender reputation decide whether it ever matters.Final notice"Final notice" is a high-pressure urgency phrase that scammers and phishing emails lean on heavily, so spam filters treat it as a negative content signal. It is a weighted signal, not an automatic block: one mention in a genuine, well-authenticated email rarely sends you to spam on its own, but it raises your content-risk score — and reads as a deceptive subject line if there's no real deadline behind it.Hurry"Hurry" is a false-urgency word that pressures the reader to act before they think, so spam filters treat it as a negative content signal. It's a weighted tiebreaker, not an automatic block — a single "hurry" rarely sinks a well-authenticated email, but it scores worse stacked with caps, exclamation marks, or other urgency words.Last chance"Last chance" is a false-urgency phrase that pressures the reader to act before an offer "disappears," so spam filters and trained recipients treat it as a negative content signal — especially in the subject line, in all caps, or stacked with deadlines and exclamation marks. It's a weighted content signal, not an automatic block: one honest "last chance" on a well-authenticated, reputable domain rarely lands you in spam by itself.Limited time“Limited time” is a false-urgency phrase that's a staple of promotions and scams, so spam filters treat it as a negative content signal — most of all in the subject line and in the intensified form “limited time offer”. A real, specific deadline stated as a fact is far lower-risk than vague countdown language.Today only"Today only" is a false-urgency phrase that pressures the reader to act before they think — a hallmark of promotions and scams — so spam filters treat it as a negative content signal, especially in the subject line or stacked with caps, exclamation marks, and other urgency words. It's a weighted signal, not an automatic block: one honest "today only" from an authenticated, well-reputed sender rarely gets filtered on its own.Urgent“Urgent” is a false-urgency word that pressures the reader to act before they think — a hallmark of promotions, phishing, and scams — so spam filters treat it as a negative content signal, especially in the subject line, in caps, or with extra punctuation. It's a weighted signal, not an automatic block: one calm, factual “urgent” from an authenticated, well-reputed sender usually still reaches the inbox.
Money & freebies
Be your own boss"Be your own boss" is income-opportunity language that turns up constantly in MLM pitches, work-from-home scams, and get-rich-quick mail, so spam filters and wary recipients treat it as a negative content signal. It's a weighted tiebreaker, not an automatic block — but because it so rarely appears in genuine 1:1 business email, it skews a message toward looking promotional or fraudulent.Cash"Cash" is a classic money-bait word that filters weigh as a weak negative content signal, because it appears far more in promotions, get-rich-quick pitches, and scams than in normal 1:1 mail. It's a tiebreaker, not a block — one factual mention from a well-authenticated domain rarely sends you to spam on its own.Cheap"Cheap" is a price-bait word that turns up constantly in discount blasts and bargain scams, so spam filters treat it as a weak negative content signal — it only matters in combination with weak authentication, poor reputation, and other risk markers. A single "cheap" in a genuine, well-authenticated message rarely lands you in spam on its own; the risk comes from density, intensifiers, and context (subject line, ALL CAPS, or stacking with other money words).Discount"Discount" is a money-and-offer word that's heavy in promotions and scams, so spam filters and trained recipients treat it as a weak negative content signal — most of all in the subject line, in all caps, or stacked with urgency. It's a tiebreaker, not an automatic block: a single, honest "discount" from a well-authenticated domain with a good reputation usually reaches the inbox.Earn money"Earn money" is income-promise language that spam filters and recipients associate with work-from-home schemes, MLM pitches, and get-rich-quick scams, so it reads as a weak negative content signal — especially in a subject line or stacked with other money words. It's a weighted signal, not an automatic block: one mention in a genuine, well-authenticated email rarely sinks you on its own.Easy money"Easy money" is a classic get-rich-quick phrase that dominates scams, phishing, and financial spam, so filters and recipients treat it as a strong negative content signal — especially in a subject line or stacked with caps, dollar signs, and other money words. It's a weighted content signal, not an automatic block: authentication and a good sending reputation are what actually keep you out of the spam folder.Extra income“Extra income” is a money-and-earnings phrase that appears constantly in MLM pitches, side-hustle scams, and investment spam, so filters and recipients treat it as a negative content signal — strongest in the subject line or stacked with “fast”, “easy”, or “$$$”. It's a weighted signal that nudges your spam score, not an automatic block: one factual mention on a clean, authenticated domain usually still reaches the inbox.Fast cash"Fast cash" pairs a money word with a speed promise — the signature of get-rich-quick and payday-loan scams — so filters and recipients read it as a negative content signal, especially in the subject line or stacked with other money and urgency words. It's a weighted signal that nudges your risk score, not an automatic block: one mention in a genuine, authenticated email rarely sends you to spam on its own.Financial freedom"Financial freedom" is an income-promise phrase that shows up constantly in MLM pitches, crypto hype, and investment scams, so it reads to filters and recipients as an "opportunity pitch." It's a weighted content signal, not an automatic block — one mention in a genuine, well-authenticated email rarely lands you in spam on its own.Free“Free” is one of the most over-used words in promotional and scam email, so spam filters and recipients treat it as a weak negative signal — especially in the subject line, in all caps, or stacked with other money words like “cash” and “$$$”. One “free” in a genuine, well-authenticated message rarely lands you in spam on its own; the risk comes from density and context.Free gift"Free gift" pairs the most over-used promotional word ("free") with a classic giveaway hook, so spam filters and recipients treat it as a weak negative content signal — it appears far more often in marketing blasts and scams than in genuine 1:1 mail. It is a weighted signal, not an automatic block: one mention from an authenticated, well-reputed sender rarely lands you in spam by itself.Free money“Free money” is one of the highest-risk money-and-freebie phrases, because it’s the language of giveaways, get-rich-quick schemes, and outright phishing (“claim your free money now”). It’s a content signal, not an automatic block — but a heavy one, especially in a subject line, in all caps, or on a cold, unauthenticated domain.Free trial“Free trial” pairs the most over-used promotional word (“free”) with a sales-y call to action, so spam filters treat it as a mild negative content signal — especially in the subject line, in caps, or stacked with urgency. It’s a weighted signal, not an automatic block: one honest mention from an authenticated, well-reputed sender usually reaches the inbox just fine.Lottery"Lottery" is one of the most scam-associated words in email — it's the signature of advance-fee "you've won!" fraud — so spam filters treat it as a strong negative content signal, especially in a subject line or paired with prizes, winnings, and a request to act. It's a content signal, not an automatic block: a legitimate, well-authenticated email that happens to mention a lottery isn't doomed, but the word carries far more risk than a neutral money word.Make money"Make money" is a content signal email filters treat with suspicion because it's so heavily used in get-rich-quick spam and scams — especially as "make money fast" or in a subject line. It's a weighted risk factor, not an automatic block: a single mention from an authenticated, reputable domain rarely sends you to spam on its own.Money back“Money back” — usually as “money-back guarantee” — is a classic direct-response phrase that spam filters treat as a weak negative content signal, because it shows up far more in promotions and refund scams than in normal 1:1 email. It’s a tiebreaker, not an automatic block: one factual mention from an authenticated, well-reputed sender rarely lands in spam on its own.Prize"Prize" is a high-risk content signal because spam filters and recipients associate it with sweepstakes, giveaways, and "you've won!" scams — but it's a weighted tiebreaker, not an automatic block. One honest mention from an authenticated, reputable sender rarely lands you in spam on its own.Winner“Winner” is heavily abused in prize, sweepstakes, and lottery scams, so spam filters treat it as a negative content signal — especially in the subject line or stacked with “congratulations”, “claim”, and a link. It nudges your content-risk score rather than blocking you outright; authentication and reputation decide most of where the message lands.Work from home“Work from home” is a content signal that filters distrust because it dominates get-rich-quick, MLM, and fake-job scams — especially in a subject line or beside income claims like “earn $$$”. It is a weighted tiebreaker, not an automatic block: a single contextual mention from an authenticated, well-reputed domain rarely lands you in spam on its own.
Overpromise
100% guaranteed"100% guaranteed" is a classic overpromise phrase that spam filters treat as a negative content signal, because absolute, too-good-to-be-true claims have a long history in scams, phishing, and aggressive marketing blasts. It is a weighted signal, not an automatic block — one mention on a well-authenticated, reputable domain rarely sinks an email by itself; the risk comes from stacking it with caps, punctuation, and other hype words.Guarantee“Guarantee” is an over-promise word: it shows up constantly in offers that sound too good to be true, so spam filters treat it as a negative content signal — especially intensified forms like “100% guaranteed” and “risk-free”. A genuine, specific guarantee stated plainly is far lower-risk than a vague superlative.Instant access"Instant access" is an overpromise phrase — the kind of giveaway CTA that shows up far more in lead-magnet and promotional spam than in real 1:1 email, so filters treat it as a weak negative content signal. It nudges your content-risk score up, but it never sends mail to spam on its own: authentication and reputation decide that.Lose weight"Lose weight" is a health-claim phrase that filters and recipients treat as a weak negative content signal, because diet, supplement, and pharmaceutical scams have leaned on weight-loss promises for decades. It's a tiebreaker, not an automatic block — one factual mention in a genuine, well-authenticated email from a domain with good reputation rarely lands you in spam on its own.Miracle“Miracle” is a classic overpromise word: it claims an extraordinary, too-good-to-be-true result — the exact pattern scam and health-fraud mail are built on — so filters treat it as a mild negative content signal. It’s a tiebreaker, not a block: one “miracle” on a well-authenticated domain rarely lands you in spam by itself, but it raises your content-risk score and compounds with other signals.No credit check"No credit check" is a financial overpromise phrase that dominates predatory-loan offers and outright scams, so spam filters and recipients treat it as a negative content signal — especially paired with "guaranteed approval" or "bad credit ok". It is a weighted tiebreaker, not an automatic block: it raises your content-risk score but rarely sinks a well-authenticated email on its own.No risk“No risk” is a guarantee-style overpromise that filters and recipients associate with scams and high-pressure sales (“no risk, guaranteed”, “100% risk-free”), so it counts as a weak negative content signal — not an automatic block. One honest “no risk” from a well-authenticated, reputable sender rarely lands you in spam on its own; the danger is density and the company it keeps.Once in a lifetime"Once in a lifetime" is an exaggerated scarcity-and-overpromise phrase — it claims an opportunity will never come again — so spam filters and skeptical readers treat it as a weak negative content signal, especially in a subject line or stacked with other urgency words. It's a tiebreaker filters weigh in combination with authentication, reputation, and formatting, not a word that blocks delivery on its own.Risk-free"Risk-free" is an overpromise phrase that scammers and aggressive marketers have over-used for years, so spam filters and skeptical readers treat it as a weak negative content signal — strongest in the subject line or stacked with "guarantee", "100%", or "money-back". It nudges your content-risk score; it does not block mail on its own, since one honest use from an authenticated, well-reputed sender usually still reaches the inbox.Satisfaction guaranteed"Satisfaction guaranteed" is a classic over-promise phrase that scam and hard-sell email have leaned on for decades, so spam filters treat it as a weak negative content signal — strongest in subject lines and intensified forms like "100% satisfaction guaranteed." It nudges your content-risk score rather than blocking a message; a single, truthful mention from an authenticated, well-reputed sender rarely lands you in spam on its own.Weight loss"Weight loss" is a high-scrutiny health phrase that spam filters and recipients associate with diet scams, miracle-cure mailers, and unregulated supplement pitches, so it nudges up a message's content-risk score — especially in the subject line or stacked with words like "miracle", "instant", or "guaranteed". It's a weighted content signal, not an automatic block: a single, honest mention from an authenticated, well-reputed sender usually still reaches the inbox.While you sleep"While you sleep" is a passive-income overpromise — "earn money while you sleep", "make money while you sleep" — that scams and get-rich-quick offers lean on, so filters and recipients treat it as a negative content signal. It's a weighted tiebreaker, not an automatic block: one tired metaphor on a well-authenticated domain rarely sinks an email by itself.
Shady / phishing
Account suspended"Account suspended" is one of the most heavily impersonated phrases in phishing — the FTC names a "suspended" account as a textbook lure — so spam filters and security gateways treat it as a strong negative content signal. It's a content signal weighed against your authentication and reputation, not an automatic block, but it's a louder signal than most words because it mimics credential-harvesting scams.Claim your prize"Claim your prize" is one of the most heavily abused phrases in lottery, sweepstakes, and phishing email, so spam filters and recipients treat it as a strong negative signal that reads as bait. It's a content signal that raises your risk score in combination with other factors — not an automatic block — and a clean, authenticated domain matters far more than any single phrase.Click here“Click here” is a low-trust call-to-action associated with promotions, phishing, and link-bait, so it's a mild spam signal — and it's bad practice for accessibility and SEO too. The bigger deliverability risk usually isn't the phrase itself but what it's attached to: lots of links, shortened or mismatched URLs, and link-heavy, text-light emails.Congratulations"Congratulations" is the signature opening of prize, lottery, and "you've won" scams, so spam filters and recipients treat it as a mild negative content signal — most when it congratulates a stranger for nothing real and pairs with "you've been selected" and a claim link. It's a weighted signal, not an automatic block: deliverability is driven by authentication and reputation, and one genuine "congratulations" from a well-authenticated sender rarely lands in spam on its own.Dear friend"Dear friend" is a generic, name-free greeting that reads as mass mail, so filters and recipients treat it as a phishing/bulk signal — it's the classic opener of advance-fee scams and impersonal blasts. It's a content signal, not an automatic block: it raises your risk score and erodes trust, but it only sinks an email in combination with weak authentication, a cold reputation, and other red flags.Multi level marketing"Multi level marketing" is strongly associated with recruitment pitches, "income opportunity" spam, and outright scams, so filters and recipients treat the phrase as a negative content signal — especially in a cold, unsolicited email. It's a tiebreaker, not an automatic block: one honest mention from an authenticated, well-reputed domain rarely lands you in spam by itself, but stacked with income claims and a cold reputation it pushes you toward the junk folder.No strings attached"No strings attached" is a reassurance phrase that scammers over-use to make a too-good-to-be-true offer sound safe, so spam filters treat it as a weak negative content signal — especially when it's stacked with money or urgency words. It's a tiebreaker, not an automatic block: one mention from a well-authenticated domain with a good reputation rarely lands you in spam on its own.Pre-approved"Pre-approved" tells the reader a decision has already gone in their favor — a framing so heavily used in credit-card, loan, and phishing mail that filters treat it as a negative content signal. It's a weighted signal, not an automatic block: one mention in a genuine, authenticated message rarely lands you in spam by itself, but it raises your content-risk score and compounds with everything else.This is not spam"This is not spam" is a defensive disclaimer that backfires: legitimate senders rarely need to insist they aren't spam, so filters and recipients read the phrase as a tell of exactly the mail it denies being. It's a weighted content signal at the "shady" end of the scale — never an automatic block on its own, but one of the more self-defeating phrases you can put in a cold email.Verify your account"Verify your account" is the single most recognizable phishing lure in email, so filters and trained recipients treat it as a strong negative content signal — it almost always precedes a request to click a link and re-enter credentials. It's a weighted signal, not an automatic block: a properly authenticated transactional message can use it safely, but in cold or unsolicited mail it reads as an account-takeover scam.Wire transfer"Wire transfer" is a phishing-associated phrase that sits at the center of business email compromise (BEC) and payment-fraud scams, so spam filters and email security gateways treat it as a negative content signal — especially alongside urgency, secrecy, or a new bank account. It's a weighted signal, not an automatic block: a routine, well-authenticated payment email rarely lands in spam on the phrase alone.You have been selected"You have been selected" is a classic prize-and-reward bait phrase that scam and phishing email use constantly, so spam filters and wary recipients treat it as a negative content signal — especially when it's paired with a reward, a deadline, or a link. It's a weighted tiebreaker, not an automatic block: authentication and sender reputation decide most inbox placement.You won"You won" is the opening line of a whole genre of scam and phishing mail — fake lotteries, sweepstakes, and prize notifications — so spam filters and trained recipients treat it as a strong negative content signal, especially about a contest the reader never entered. It's a weighted signal, not an automatic block: deliverability is dominated by authentication and reputation, but "you won" is exactly the phrase that tips a borderline email into the spam folder.
Unnatural / salesy
Buy now"Buy now" is a hard, transactional call to action that rarely appears in genuine one-to-one email but is everywhere in promotions and scams, so spam filters treat it as a weak negative content signal — strongest in the subject line or stacked with urgency. It's a tiebreaker, not a block: one "buy now" from an authenticated, well-reputed sender usually still reaches the inbox.Order now"Order now" is a hard-sell call-to-action that appears far more often in promotions and scams than in normal 1:1 email, so spam filters treat it as a weak negative content signal — especially in a subject line, in all caps, or stacked with urgency and money words. It nudges your content-risk score; it does not block the message by itself.
