I do a lot of negotiating with blocklists and ISPs on behalf of my clients and recently was dealing with two incidents. What made this so interesting to me was how differently the clients approached the negotiations. In one case, a client had a spammer slip onto their system. As a result the client was added to the SBL. The client disconnected the customer, got their IP delisted from the SBL and...
Two articles showed up in my RSS feed in the last 24 articles that touched on different aspects of the same issue. Senders should improve their email marketing program even when they are working well. Stephanie Miller over at ReturnPath addresses the lost revenue from current programs. Consider that if we can earn a nearly $60 ROI by creating email programs that are compelling to just a few...
Ken has a followup to his article last week about the EEC spamming. Multiple e-mails obtained by this newsletter clearly show VIV was prospecting the EEC member list from its servers in violation of the EEC’s own privacy policy. […] Moreover, one reader sent this newsletter two separate free issues of two different editions of VIV that were spammed into his inbox on two different days. So...
Ben over at MailChimp has an article talking about a recent experience with Postini and an actual bug that causes Postini to interact badly with another spamfilter and block non-spam.
Al wrote a post commenting on my post from last Thursday on spamfilters talking to senders who are being filtered. I think his take on it is close to mine. I would point out that Google has a pretty opaque system and no feedback to senders, but a lot of people seem to think their filters are accurate and do a good job. Overall, I think there is room for discussion and feedback between senders and...
JD posed a question in my post about Postini and trying to sort out a customer getting marked as spam by their filtering mechanism and I think it bears more discussion than can be done in comments. And sure, it’s a best practice for filtering companies to respond politely to requests from filterees. But is it a requirement? Do senders have a right to demand explanations? There is not really an...
Many of my clients come to me when they end up with delivery problems due to the actions of affiliates. These can either be listings in some of the URL blocklists (either public or private) or escalations of IP based listings. In many of the cases I have dealt with affiliates, the affiliates have sloppy mailing practices or are out and out spammers. Recently the FTC settled with Cyberheat over...
Al posted an analysis on DNSBL Resource about the effectiveness of the FiveTen blacklist. He says: Analysis of the raw data suggests to me that Fiveten’s poor (high) false positive rates is primarily due to Fiveten’s listing of “bulk mailers that don’t require closed loop confirmation opt-in from all their customers.” As a result, Fiveten has thousands of senders listed that...
