Twisting information around

One of my mailing lists was asking questions today about an increase in invitation mailings from Spotify. I’d heard about them recently, so I started digging through my mailbox to see if I’d received one of these invites. I hadn’t, but it clued me into a blog post from early this year that I hadn’t seen before.
Research: ESPs might get you blacklisted.
That article is full of FUD, and the author quite clearly doesn’t understand what the data he is relying on means. He also doesn’t provide us with enough information that we can repeat what he did.
But I think his take on the publicly available data is common. There are a lot of people who don’t quite understand what the public data means or how it is collected. We can use his post as a starting off point for understanding what publicly available data tells us.
The author chooses 7 different commercial mailers as his examples. He claims the data on these senders will let us evaluate ESPs, but these aren’t ESPs. At best they’re ESP customers, but we don’t know that for sure. He claims that shared IPs means shared reputation, which is true. But he doesn’t claim that these are shared IPs. In fact, I would bet my own reputation on Pizza Hut having dedicated IP addresses.
The author chooses 4 different publicly available reputation services to check the “marketing emails” against. I am assuming he means he checked the sending IP addresses because none of these services let you check emails.
He then claims these 4 measures

Debating Appending

There was a session at the recent Email Insiders Summit that discussed appending. I wasn’t there, but I’ve been hearing about the session, including one description that involved the term ‘fist fight.’
I have found a couple articles about the session.
E-Append Comes Under Fire
Email Insider Summit Email Append Panel — The Day’s Hottest Debate
I encourage folks to read both articles and watch the video posted by Return Path. I agree with different points by folks on both sides of the debate. Appending can be a useful acquisition strategy for some companies. But we can’t pretend there’s any permission involved in common appending strategies.
Ignoring the lack of permission, I believe that the companies saying it is a successful strategy share some common factors.

Delivery challenges increasing

Return Path published their most recent Global Deliverability report this morning. (Get the Report) This shows that inbox placement of mail has decreased 6% in the second half of 2011. This decrease is the largest decrease Return Path has seen in their years of doing this report.
To be honest, I’m not surprised at the decrease. Filters are getting more sophisticated. This means they’re not relying on simply IP reputation for inbox delivery any longer. IP reputation gets mail through the SMTP transaction, but after that mail is subject to content filters. Those content filters are getting a lot better at sorting out “wanted” from “unwanted” mail.
I’m also hearing a lot of anecdotal reports that bulk folder placements at a couple large ISPs increased in the first quarter of 2012. This is after the RP study was finished, and tells me increased bulk folder placement is more likely to be a trend and not a blip.
One of the other interesting things from the RP study is that the differences are not across all mail streams, but are concentrated in certain streams and they vary across different regions.
