What actually gets email filtered
It is worth being direct: rewriting copy is rarely the fix. Filtering decisions weight domain authentication, sending volume, pacing, recipient engagement and complaint history far above word choice. A well-written message sent from an unauthenticated domain at four thousand an hour from one mailbox will be filtered. A plainly written one, properly authenticated and paced, generally will not.
This tool is useful for catching the obvious \u2014 a subject in capitals, eleven links, no unsubscribe wording \u2014 before you send. Treat a good score as removing an avoidable contributing factor, not as a prediction of where the message lands.
The checks it runs
Trigger phrases with a long association with unsolicited bulk mail; the proportion of capital letters; exclamation-mark density; the number of links relative to the length of the copy; overall word count; and whether any unsubscribe or opt-out wording appears at all. That last check is the one worth acting on regardless of score \u2014 commercial email legally requires a working opt-out, and its absence drives recipients to the spam button instead.
About this checker.
What it measures, and the considerably more important things it does not.
How accurate is a spam score checker?
Treat it as directional. Modern filters do not use a banned-word list — they weight domain authentication, sending volume, pacing, recipient engagement and complaint history far above word choice. This tool catches the obvious problems, which is genuinely useful, but no content checker can predict inbox placement.
What does the score actually measure?
Trigger phrases historically associated with unsolicited bulk mail, the proportion of capital letters, exclamation-mark density, the number of links relative to length, overall word count, and whether unsubscribe wording is present at all.
Is my email copy sent to your servers?
No. The scoring runs entirely in your browser in JavaScript. Nothing you type leaves your machine, and nothing is stored. You can confirm this by opening your browser's network tab while typing.
My score is high but my emails still go to spam. Why?
Almost certainly because the cause is not your copy. Check three things in order: whether SPF, DKIM and DMARC pass and align for your sending domain, how much volume one mailbox is sending in a short window, and how engaged your list actually is. Those three account for the large majority of filtering, and no rewrite will compensate for them.
Copy is the smaller half of the problem.
What usually decides placement is how the message was sent \u2014 authentication, volume per mailbox, and pacing. That is the part Email.biz.pk handles.
