GuideStar: The Consequences of Bad Bounce Processing

GuideStar, a highly respected non-profit organization whose work is to collect information about and provide resources to other non-profit organizations, is still sending email to an email address that almost certainly did request that email — sometime in the late 1990s. The email address was closed and disabled in 2004, however, and was not re-enabled as a spamtrap until 2008. Four years of 500-level SMTP rejections failed to get it removed from GuideStar’s list. How much of that list now consists of old, dead email addresses? How much of it now consists of spamtraps? The ESP is fortunately Lyris, which actually cares about good list management and should be able to help GuideStar fix this problem.

I mention this not because I consider GuideStar a spammer (I do not), but because this is such a common problem especially among non-profit organizations. I see bulk email sent to email addresses that have been closed for over a decade by local churches/synagogues/mosques (yes, a couple of those), small charities, local affiliates of large charities, activist groups, and political organizations. Some of these organizations spam non-opted-in email addresses intentionally, but many do not. They simply do not manage bounces or handle list hygiene with the same professional care that most companies have learned that they must.

Many non-profit organizations do not realize that their CAN-SPAM exemption in the United States, similar legal exemptions elsewhere, and the reality that most large blacklists and spam filters treat them with a degree of sympathy and deference does not mean that they’re exempt from the normal rules of proper bulk email management on the Internet. Constant delivery attempts to dead email addresses and loads of unwanted email to moribund email addresses or even role addresses do eventually get noticed, even when a cause is good. ISPs and companies that see enough spam even from a good group are likely to drop their sending IPs in the local router table so that they won’t have to deal with the mess.

GuideStar, after you get your list cleaned up, perhaps you could consider writing an article about the need for proper management of bulk email lists and posting it on your site, as a resource for all of the other non-profits you serve?
