How Spam Detection Works

Platform spam filters and email providers scan content for patterns, not intent. They don't know you're a legitimate business. They see patterns - and if those patterns match what spammers do, your content gets flagged.

TextScore's spam analyzer checks your text against the same pattern categories these filters watch for. Fix the patterns, and your content reaches its audience.

Financial Promises

These are the highest-risk spam triggers. Financial language is the bread and butter of scam emails, so filters are aggressive here.

Phrases That Get Flagged

• "Make money fast"
• "Earn $X per day/week/month"
• "Financial freedom"
• "Guaranteed income"
• "Double your investment"
• "No risk"
• "Get paid to..."
• "Cash bonus"

How to Rewrite

Flagged: "Earn $5,000 per month with our guaranteed system!"

Clean: "Our clients typically see revenue growth within the first quarter. Here's how the program works."

The clean version makes no specific financial promise. It references results without guaranteeing them. It focuses on process, not payout.

Urgency Language

Urgency is a core tactic in spam and phishing. Filters watch for it closely.

Phrases That Get Flagged

• "Act now"
• "Limited time offer"
• "Don't miss out"
• "Expires today"
• "Only X spots left"
• "Last chance"
• "Urgent"
• "Immediately"

How to Rewrite

Flagged: "ACT NOW - Limited time offer expires TODAY! Don't miss out!"

Clean: "Registration closes on March 15. Save your spot if you're interested."

The clean version gives a specific date instead of vague urgency. It's calm and informative instead of pressuring.

Excessive Formatting

Formatting abuse is one of the easiest spam triggers to fix - and one of the most common mistakes legitimate marketers make.

Patterns That Get Flagged

• ALL CAPS words or sentences.
• Multiple exclamation marks (!!!).
• Excessive emoji use in subject lines or main text.
• Colored or oversized text in emails.
• Dollar signs, especially combined with numbers ($$$).
• Special characters used as attention grabbers.

How to Fix

Flagged: "FREE!!! Get YOUR Copy NOW!!! $0 TODAY ONLY!!!"

Clean: "Download your free copy today."

Same message. One gets filtered. One doesn't.

Promotional Patterns

Some phrases are fine on their own but become spam triggers when combined or overused.

Phrases to Watch

• "Click here" (especially without context)
• "Buy now"
• "Order today"
• "Special promotion"
• "Exclusive deal"
• "Unsubscribe" in unusual positions
• "This is not spam"
• "You have been selected"

How to Rewrite

Flagged: "You've been selected for an exclusive deal! Click here to buy now and save 70%!"

Clean: "We're offering 70% off this week. Here's what's included and how to get the discount."

The clean version drops "selected" (implies you didn't opt in), "exclusive" (overused trigger), and "click here" (vague CTA). It keeps the discount but frames it informatively.

TextScore's spam analyzer scans your text against a database of known spam patterns. It checks for:

• Individual trigger words: Words and phrases that appear on spam watchlists.
• Pattern combinations: Multiple mild triggers in the same text can add up to a high spam score.
• Formatting analysis: Caps ratio, punctuation density, and special character frequency.
• Link patterns: URLs that match common spam distribution methods.
• Density scoring: How concentrated the spam-like language is relative to your total word count.

Your spam score reflects all of these factors combined. A score under 10 means your content is clean. Between 10 and 25 means you have some patterns to review. Above 25 means you have serious flags that will likely cause filtering on most platforms.

Run through this list before publishing any content:

• No ALL CAPS words (except acronyms).
• No more than one exclamation mark per paragraph.
• No financial promises or guarantees.
• No vague urgency ("act now," "limited time").
• Specific CTAs instead of "click here."
• Clean links - no URL shorteners, no suspicious domains.
• TextScore spam score under 15.

Follow this checklist and your content will pass spam filters on every major platform and email provider.
