Guaranteed Email Delivery
By John Quaglieri on December 22nd, 2015
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:
- 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.
