Analyze your email subject and content for spam triggers, phishing keywords, and formatting issues instantly without sending any emails.
An Email Spam Checker is a tool that analyzes the subject and body of your email to identify elements that might trigger spam filters. By analyzing keywords, punctuation, text formatting, and link structures, it calculates a spam score to help you improve your email deliverability.
Emails are sent to the spam or junk folder when email providers (like Gmail, Outlook, or Yahoo) detect suspicious behavior. Common triggers include excessive use of uppercase letters, aggressive sales keywords like "100% free" or "Buy now", too many exclamation marks, missing subject lines, or the inclusion of untrusted shortened URLs.
This tool performs a local, read-only analysis using pattern matching algorithms. It scans your text for known phishing and spam phrases, checks the ratio of uppercase to lowercase letters, counts punctuation frequency, and verifies link formatting.
