Disclaimer: Even though our testing tool indicated your email's content is not flaged as Spam. It does not guarantee successful delivery of your email when you try to send out via your email server.

Our checking basically only covers the suject and content of your email. It does not check your network or email server setup and configuration. A misconfigured network or mail server may cause your email to mark as spam as well. A bad IP reputation of your delivery email server will also causing the mail being blocked by recipient mail server.

However if you received a high spam score from our tool which is based on SpamAssassin, most likely you will get high spam score from your recipient's mail server when you do the actual delivery.
