FAQ

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 a "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 might trigger a spam filter.Fixing your message is simple:

Q. Is my email address safe? - you won't send us spam yourself, will you?

A. We do not share your email address or any other information with anyone, and we will not send you any spam. We do track the test results in order to improve our service.

Q. Don’t you think that spammers would use your tool and world spam would increase?

A. We monitor the usage of this service, to ensure that any abuse is minimised. This tool was created for people and companies that send newsletters and want to know if their newsletter would get filtered.

Q. I checked my email with your service and I still get blocked. Why?

A. Spam filters check many aspects of emails received. You should check the IP address from which the email is sent to see if it is black-listed. There are many sites that can check if your IP is black-listed. Two of the popular ones are MXToolbox and DNSStuff .

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 then 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.
