We score it with SpamAssassin
Your copy runs through the real SpamAssassin engine. You get the overall score against the 5.0 spam threshold and a plain verdict in a second or two.
Reword the triggers and re-check
See every rule that fired, with points and a plain-English reason. Reword the specific phrases that scored, keep your offer, and re-check to watch the score drop.
How to read your score
SpamAssassin adds points for each content rule your copy trips. The total is compared against the spam threshold of 5.0. Lower is better, and 0 means nothing fired.
Well below the threshold. Your copy is clean on the content axis.
Approaching the threshold. Worth rewording the lines that scored.
At or over the threshold. SpamAssassin-based filters are likely to treat this as spam.
What actually moves a spam score
Most spam-word advice overstates the small stuff. In testing, stylistic signals like ALL CAPS, exclamation marks and a sense of urgency barely move a SpamAssassin score on their own. The real weight sits in content patterns, for example copy built around large sums of money or certain high-pressure offer phrasings.
That matters because the fix is almost never to abandon your offer or your angle. SpamAssassin reacts to phrasing, not to your strategy. When a rule fires, the useful move is to reword the specific line that triggered it and keep everything else. The checker shows you exactly which line that was and how many points it added.
A clean result is not a promise of inbox placement. Content is one part of deliverability, and usually not the biggest: reputation, authentication and warmup matter more. Think of this as a fast, free way to remove one avoidable reason your copy gets filtered before a send, especially when your prospects sit behind SpamAssassin-based filtering.
