Fix Specific Triggers
The checker points to exact phrases and formatting problems that trip filters, so fixes take minutes.
Reach More Inboxes
Cleaner content clears filters more often, which means more opens, clicks, and replies from your list.
A spam score checker analyzes an email before you send it and estimates how likely filters are to flag it as junk. It scans your subject line, body copy, HTML, and links against common spam rules, then returns a score with the specific triggers behind it. Marketers use it to clean up risky wording and formatting so more messages reach the inbox rather than the spam folder.
What the spam score checker checks
The spam score checker examines the parts of an email that filters weigh most heavily. It reviews your subject line for trigger words, excessive capitals, and misleading punctuation, then reads the body for a healthy balance of text and images. It looks at your HTML for broken tags and bloated code, checks that links point to reputable domains, and confirms an unsubscribe link is present. Some checks also consider whether your sending domain has valid authentication. Each factor adds or subtracts points, and the tool rolls them into a single spam score alongside a list of the exact elements pulling that number up, so nothing that hurts deliverability stays hidden.
How to read your spam score and fix triggers
Lower scores are better, so treat every flagged item as a quick win. If a trigger word like free, guarantee, or act now inflates your score, rewrite the line in plain, specific language. Rebalance emails that lean too heavily on images by adding real text, and trim inline styles or leftover code that clutter the HTML. Swap shortened or unfamiliar links for full, branded URLs, and make sure the unsubscribe option is easy to find. Fix any authentication warnings at the DNS level. After each change, run the spam score checker again and watch the number fall until your email clears the thresholds that mailbox providers apply.
Why your spam score shapes inbox placement
Every message you send carries a spam score in the background, and mailbox providers use similar logic to route mail. A high score can send even wanted emails to junk, where they go unseen and quietly drag down open and click rates. Worse, repeated spam folder placement teaches providers that recipients ignore you, which erodes your sender reputation and hurts future sends too. Checking the score before you hit send lets you catch the wording and formatting that trip filters while you can still fix it. Over time, cleaner emails protect your list, lift engagement, and keep your marketing reaching real people.
Frequently Asked Questions
How does the Spam Score Checker score my email?
