IsNotSpam online spam checker was created to help you test email and newsletter content, and alert if it is likely to trigger spam filters.

Simply compose your email and send it to the email address listed at the top of the page, using your usual mail server. You will be able to view an online report detailing potential problems (if any) with your email. Our software automatically checks the main elements which cause emails to be rejected by recipient mail servers. The following tests will be performed:

• SPF Check
• Sender-ID Check
• DomainKeys Check
• DKIM Check
• SpamAssassin Check

You'll be able to view the results of these tests online within a few seconds, by clicking the VIEW YOUR REPORT button above.
