Lyris Technologies recently completed an email deliverability study, showing an overall improvement by internet service providers (ISP) in their ability to accurately filter permission-based messages. Lyris is a subsidiary of J.L. Halsey Corporation and provider of email marketing software and anti-spam products.
The company monitored 72,406 permission-based email messages sent to 41 ISPs over a three-month span. All were legitimate messages that should have been allowed to pass through filtering mechanisms and into inboxes.
Some of the top-performing ISPs were Outblaze, Earthlink, PeoplePC, USA.net and RoadRunner, all of who delivered 95 percent of the legitimate emails.
Google's service Gmail was another top performer and one of the biggest improvers with a 96 percent accuracy rating, up from 84 percent in the first quarter.
"ISPs appear to be getting better at distinguishing legitimate email marketing messages from spam. 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," says Robb Wilson, vice president of deliverability, Lyris.
