My email message was flagged as spam and was either delivered to a spam mail folder or deleted.

Spam or unsolicited junk mail filters are used make a determination of whether or not unsolicited email is being received.  There is no absolute way to separate unsolicited email from regular email.  As such, a number of different criteria are applied to determine unsolicited mail.  Some of the criteria are:

• The Internet Service Provider (ISP) from which the email originated.  Some ISPs have tolerant policies towards the senders of unsolicited mail.
• The type of mail server from which the message originated.  Mails servers located on dynamic IP addresses or that contain "open relays" tend to be originators of unsolicited mail.
• The domain from which the email originated.  Some companies are known to send large volumes of unsolicited mail.
• The content of the message.  The occurrence of certain words or phrases in an email can be considered as spam.

Doubleknot insures the delivery of your email by making certain we comply with all the best practices and standards for volume email senders.  This includes compliance with abuse notification, opt-out lists, reverse lookup, and disallowance of relays.  We also work with the major Internet Service Providers to make certain we are listed as a trusted email provider.
