99.99% of email accounts use spam filters these days. Spam filters recognize spam messages by analyzing message content for spam characteristics. Sometimes these filters fail and mark legitimate emails as spam. Such emails are sent to the Spam folders and are not seen by the recipient. This filter failure is called "false positive" as it marked a legitimate non-spam message as spam. Newsletter senders and email marketers need to check that their emails do not have spam characteristics in order to lower the risk of their newsletters being marked as spam. By testing your message with "Is Not Spam" you will get a report if and why your message triggered any spam filter.Fixing your message is simple:
- Change your message wording so it does not include known spam phrases
- Cleanup your HTML code
- Change your HTML so your message layout focuses on your content

A. Spam filters check many aspects of email received: email content (like this tool), email software sending the email, the IP from which the email is sent, sender email address etc. If you checked your email here and it was fine (and you are not a spammer), most chances are that the IP you are sending your email from was black-listed.

Q. My email triggers spam filters but I must have these words in my email. What to do?
A. If these words must be included in your email leave them. Spam blocking systems score emails received and decide which email is spam based on its score. Strict spam blocking systems will block your email and less strict systems might let your email pass if it does not trigger too many filters.
