30% of email addresses on a marketing list go bad every year. It doesn’t seem that changing email addresses is that problematic.

Of course it is problematic, because any email address that is changed for that reason cannot be used as stable contact info for use between friends and colleagues. And this degrades the utility of email.

This has been the case since 1999.
So addressing the issue is clearly long overdue.

Of those 30%, I wonder how many of those addresses were addresses that people intended to use as stable addresses in the first place.   I wonder how many people obtain "throwaway" addresses specifically for the purpose of disclosing in contexts where they seem likely to be exploited by marketers, while reserving other addresses for use for mail that they want to get.

There has been published research on this. Which goes back to what Dave was saying - you really need to understand what has been done before you start proposing solutions. I have a copy of the ..pdf, but you can search google to find it, too. The title is  "ISPs and Spam: The Impact of Spam on Customer Retention and Acquisition," Gartner Inc., Stamford, Conn. June 14, 1999.

Thanks for this and other references.   I certainly agree that I need to survey the literature.   But it's not necessary to survey the literature to understand that spam is a huge problem and that existing solutions are inadequate.

(I assume this is your reference for the 30% figure also?)

But yes, I'm aware that one of the ways that people deal with spam is by changing email addresses. If spam as experienced by ordinary people were not so bad, causing them to change email addresses as a way of dealing with it, email would be more useful.

In 1999, the volume of spam was a tiny fraction of what it is today. And, yet, it was bad enough to cause 30% of people to abandon their email addresses.

And yet, a lot has changed since 1999, so the conditions that caused 30% of the people to abandon email addresses then may not be the same conditions that exist now, even if that 30% figure were about the same today as then.   (but do we even know that?)
