Paste an email message to detect content that may cause spam classification before sending. Three full analyses daily are free, with complete results and no account needed.
What does the free analysis check?
Each analysis checks your sender name, subject line, and message body for content that may cause spam classification. Results include the estimated spam probability, confidence level, detected words or phrases, and explanations.
How many free analyses can I run?
Without an account, anyone receives three full free analyses daily. Additional analyses are paid after signing in.
Does this tool guarantee inbox delivery?
No tool can measure actual inbox placement or guarantee delivery. Mailbox providers also evaluate factors outside the message text, such as sender reputation, authentication, and recipient behavior.
What features require an account?
Editing or removing words, AI rewriting, and other model choices require an account. Your email message is used only to run the analysis and is never published on the page.
