Spam Filtering Growing More Accurate, Sophisticated
Google
Improves Inbox Delivery of Permission-Based Email by
34 Percent
BERKELEY, CA — July 13, 2005 — Lyris®
Technologies, subsidiary of J.L. Halsey (JLHY.ob) and
leading provider of email marketing solutions, today
announced improved filtering of permission-based email
messages among major ISPs in the second business quarter
of 2005. Lyris publishes its findings today as part
of its quarterly ISP Deliverability Report Card, documenting
the delivery rates of over 72 thousand requested email
messages sent to accounts at 41 major Internet Service
Providers.
“ISPs appear to be getting better at distinguishing
legitimate email marketing messages from spam,”
said Robb Wilson, vice president of deliverability at
Lyris. “ Average rates of inaccurate filtering
for Q2 hovered just over one percent this quarter, which
is a marked improvement over the first part of the year.”
“This may mean ISPs are starting to use more sophisticated
filtering practices,” he added.
Google’s Gmail service followed the overall trend
toward improved email processing, with only four percent
of permission-based messages inappropriately filtered
to bulk folders—down from 16 percent in Q1. Major
ISPs garnering top deliverability scores were Outblaze,
Earthlink, PeoplePC, USA.net and RoadRunner—each
of which delivered over 95 percent of requested email
to the inbox without mislabeling or filtering it as
spam. Other top performing ISPs were Compuserve, Yahoo,
Lycos, Knology, and Mac.com.
The report was based over 72,406 legitimate permission-based
email messages monitored by the Lyris EmailAdvisor service
over a three month period from April to June. Examples
of email publications monitored by the report include
a wine tasting club’s weekly bulletin, a professional
sports team’s monthly newsletter, a national retailer’s
monthly product bulletin, a lobbying group’s political
alerts, and a non-profit’s digest of treatment
advances in neurological disease. In all cases, recipient
accounts made an explicit “opt-in” request
to receive the email messages tracked by the study.
