Guaranteed Email Delivery

InterServer shared hosting offers guaranteed email delivery of valid, non spam, and non bulk emails through the shared hosting service with the addition of compromised email detection and spam blocking. A compromised email account will be automatically detected preventing problems such as IP blacklisting. See our Private Email Hosting page for more details. Here is what InterServer offers:

Email Security

  • InterServer uses digital signature technology, checking the content of each email message against a real-time updated database of known spam signatures. A sudden uptick of spam messages identified in this way may trigger rate limiting or blocking of a sender.
  • InterServer tracks dozens of minute-by-minute statistics about each email sender. Unusual trends in message volume, suspicious content, recipient validation failures and other statistical signals enable identification of spammers.
  • InterServer consults external databases such as domain and IP reputation services to identify email messages relating to known spammers.
  • InterServer analyzes responses from email receivers to gauge whether receivers like the email being sent by your users, applications, and scripts. Based on this feedback, spammers can be identified even before other signals indicate a problem.

Email Management Features

InterServer provides easy-to-understand non-delivery reports (NDRs) when email is rejected, helping users resolve their own delivery challenges. A link provided in each NDR takes the user to an “Insights” page where they review all of the email sent from their address as well as their responses.

Whats Covered?

Email used under normal circumstances will be sent from non blacklisted ips, which constant monitoring once all spam checks have passed. The guaranteed email delivery must pass all the anti spam checks. Email deemed spammy or abusive will bounce to the sender with the error message.

Whats Not Covered?

Bulk email, mailing lists and email considered abusive, spammy, or not following generally accepted email practices. A high bounce rate, such as emails sent to non existent would be considered abusive.
