Lyris enhances EmailAdvisor
Version 3.0 of the Lyris EmailAdvisor deliverability solution includes updated ISP reports and email client previews.
Instead, subscriber feedback, such as spam complaints, is the leading cause of most marketers' deliverability obstacles.
This is the primary finding of the Lyris EmailAdvisor ISP Deliverability Report Card for Q1 2007, a quarterly research study that monitors deliverability rates for permission-based email marketing.
The EmailAdvisor Report Card also reveals that a majority of the largest US-based ISPs have the lowest rates of delivering email to the inbox.

Email sender authentication checks on the rise
A new email deliverability study from Lyris signals an increasing reliance on the Sender Policy Framework authentication method to determine whether the email is legitimate and should be delivered.
According to the EmailAdvisor Report Card, message content is not a major cause of deliverability challenges for most email marketers.
More than 1,705 unique emails were run through the EmailAdvisor content scoring application that includes the content scoring rules subset to the widely adopted Spam Assassin open source project.
The average content point score of these 1,705 unique emails was 1.04 - well below the filter's generally accepted spam identification level of 3.0 or higher.
"The main message of this quarter's EmailAdvisor Report Card for email marketers is that there are no easy fixes to senders' deliverability challenge," said Stefan Pollard, Director of Consulting Services at EmailLabs, which along with JL Halsey's Lyris and Sparklist brands has integrated with the EmailAdvisor deliverability monitoring tool.
"Changing a few keywords in the hopes of boosting inbox success rates is no substitute for adhering to email marketing best practices.
"It's an oversimplification to place blame primarily on content filters when a campaign has poor returns, when in fact most delivery challenges are due to subscriber feedback".
According to Pollard, such feedback typically takes the form of complaints by recipients who mark the message as "spam" in their respective email clients and problematic traffic patterns such as bounces and spam trap hits.
"That's why both EmailLabs and Lyris have developed deliverability programs that build on EmailAdvisor and focus on the real issues that affect a sender's deliverability," he said.
How does your content rank? Of the emails subjected to content scoring, two Spam Assassin rules that were frequently triggered generated content filter point scores of significance.
According to Pollard, most marketers should find that easy to correct.
The first rule cautions against heavy use of images, which can increase spam scores up to a full point and render poorly in email clients with image blocking enabled.
The second problem, sending messages with a "From Name" composed of numbers or symbols rather than an actual name, can also increase the likelihood of the message being flagged as spam and ending up in users' junk/bulk folders.
Of the 25 ISPs tracked by the EmailAdvisor Report Card, several leading providers rank among the top ten domains with the highest rates of delivery to the junk folder.
These include Gmail (third with 28%), Yahoo! (fourth with 19%), and Hotmail (sixth with 16%).
Noticeably absent from the top ten ISPs with the worst inbox delivery is AOL, which ranked 14th on the list with a junk delivery rate of only 2.33%.
For the study's top-ten ranked ISPs, gross deliverability was more than 90% in all cases, with average deliverability of 83.8% across the sample.
CompuServe had the highest rate of inbox delivery at 88%, with the remainder of the top-ten ranked ISPs achieving delivery rates of more than 81% in all cases.
Among international ISPs, European ISPs performed the best, followed by Australian, Canadian and finally US domains - although the disparities between regions were all within five percentage points.
"Fighting spam and other types of malicious messaging continues to be a major challenge for ISPs, who err on the side of protecting their customers and users," said Dave Dabbah, Lyris' Senior Director of Marketing.
"Marketers who adopt authentication protocols such as Domain Keys, SPF and SenderID and who actively manage their sender reputation with deliverability best practices are able to reach the inbox with their campaigns giving them a distinct advantage over other marketers that lack deliverability know-how".
Deliverability rates can be adversely affected by a number of factors in addition to individual ISP policies and sender content, including the sender's mailing history, number of complaints the sender receives, data collection practices, use of sender authentication protocols and other reputation factors.
"There are a lot of different variables to keep track of when managing deliverability," Dabbah said.
"That's why Lyris and EmailLabs deliverability consulting packages have developed metrics that give marketers a quantified way to view and understand their deliverability scenarios".
Lyris encourages senders to adhere to email marketing best practices in order to optimise their deliverability rates.
For the period beginning 1 January, 2007 and ending 31 March, 2007, the Lyris EmailAdvisor service monitored the full delivery trajectories of 440,694 production level, permission-based email marketing messages sent from 69 different businesses and non-profit organisations to multiple accounts at 54 ISP domains in the United States, Canada, Europe, and Australia.
Messages were chosen to represent a cross-section of typical email marketing and newsletter activities.
Examples of email message types monitored by the study include publishing, business-to-business, retail, travel, finance, among many others.
In all cases, the recipients to whom the emails were sent had made an explicit "opt-in" request to receive the messages at the specified email addresses.
