ReturnPath: ISP Rate Corresponds with Sender Score
The average inbox placement rate (ISP) for promotional emails correlates with the sender score of the entity sending them, according to a study conducted from January to April 2011 by ReturnPath. Data from “The Sender Reputation Report” indicates that emails from IP addresses with the highest sender score (91-100) have an average 88% ISP rate.
In contrast, emails from IPs with the lowest sender score that still indicates a legitimate address (41-50) only have a 64% ISP rate. That means IPs with a sender score of 91-100 are 38% more likely to get an email into an inbox than IPs with a sender score of 41-50. ISP rate steadily climbs along with sender score; industry average ISP rate is 80.
About the Data: This study is compiled from 7.7 billion emails sent by Epsilon in Q2 (April-June) 2011, across multiple industries and approximately 130 participating clients.
