Yesterday I talked about how I’m hearing warnings of a coming paradigm shift in the email industry. While these changes will affect all sender, ESPs in particular are going to need to change how they interact with both ISPs and their customers.
Currently, ESPs are able to act as “routine conveyers.” The traffic going across their network is generated by their customers and the ESP only handles technical issues. Responsible ESPs do enforce standards on their customers and expect mailings to meet certain targets. They monitor complaints and unknown users, they monitor blocks and reputation. If customers get out of line, then the ESP steps in and forces their customer to improve their practices. If the customer refuses, then the ESP disconnects them.
Currently standards for email are mostly dictated by the ISPs. Many ESPs take the stance that if any mail that is not blocked by the ISPs then it is acceptable. But just because a certain customer isn’t blocked doesn’t mean they’re sending mail that is wanted by the recipients.
It seems this reactive approach to customer policing may no longer be enough. In fact, one of the large spam filter providers has recently offered their customers the ability to block mail from all ESPs with a single click. This may become a more common response if the ESPs don’t start proactively policing their networks.
Why is this happening? ISPs and filtering companies are seeing increasing percentages of spam coming out of ESP netspace. Current processes for policing customers are extremely reactive and there are many ESPs that are allowing their customers to send measurable percentages of spam. This situation is untenable for the filtering companies or the ISPs and they’re sending out warnings that the ESPs need to stop letting so much spam leave their networks.
Unsurprisingly, there are many members of the ESP community that don’t like this and think the ISPs are overreacting and being overly mean. They do not think the ISPs or filtering companies should be blocking all an ESPs customers just because some of the customers are sending unwanted mail. Paraphrased, some of the things I’ve heard include:
