Dealing with blacklists

Al has a good post listing the top 5 things senders should remember when dealing with blacklists.
One of the critical things to remember about blocklists is that they are an early warning sign. Sure, some of them are one crank and his cat and will not hurt your overall delivery. A sender may be listed for totally spurious reasons . On the other hand, many of the widely used public lists and the private lists at the big ISPs, list IPs that they see as doing something wrong.
The challenge for anyone listed on any IP based blocklist is to look inside and determine what it is that they’re doing that caused the listing. The first step is to look at the technical issues, does your mail look like something coming out of infected bots? Is there a configuration problem? If the answer is no, then senders have to look at their practices. Are they sending mail to people who don’t expect it? Are they sending mail to people who didn’t ask for it? Most listings that will affect large numbers of recipients fall into the above 2 categories: technical or practices.
Technical problems can be fixed easily, once they’re identified. Permission or practice problems can also be fixed, but may require a sender reassess how they are using email and what value email brings to the business.

Marketing to businesses

“If you do stupid things, you’re going to get blocked,” says Jigsaw CEO Jim Fowler in an interview with Ken Magill earlier this week.
Jigsaw is a company that rewards members to input their valuable business contacts. Once the addresses are input into Jigsaw, they are sold to anyone who wants them. Jigsaw gets the money, the people providing information get… something, the people who provided business cards to Jigsaw members get spammed and the people who downloaded the lists get to deal with a delivery mess. Sounds like a lose for everyone but Jigsaw.
Except that now Jigsaw is listed on the SBL for spam support services. Well, that’s going to cause some business challenges, particularly given how many companies use the SBL as part of their filtering scheme.
It’s hard to think of a situation where I would appreciate someone I gave a business card to providing my information to a site that then turns around and lets anyone download it to send email to. I know, I know, there are a million companies out there I’ve never heard of that have The Product that will Solve All my Problems. But, really, I don’t want them in my work mailbox. The address I give out on my business cards is, for, y’know, people to contact me about what I’m selling or to contact me about things they’ve already purchased from me. That address is not for people to market to. I have other addresses for vendors, and even potential vendors, to contact me.
Jigsaw clearly facilitates spam to businesses by collecting email addresses and then selling them on. This is a drain on small businesses who now have inboxes full of valuable offers to wade through. Perhaps their stint on the SBL will make them reconsider their spam support services.
