Email problems are costly

Last week Zulily released their quarterly earnings. Their earnings’ report was disappointing, resulting in a drop in their stock prices. The chairman of the company told reporters on a conference call that part of the reason for the drop in earnings were due to deliverability problems “at a large ISP.”

Zulily ran into problems with a large email provider — issues which resulted in the retailer being unable to send out its daily email blasts to some customers.
No emails, no sales.

As a result of the weak earnings, Zulily stock dropped nearly 20%.
The reports don’t say specifics about what happened or which ISP was the problem. Given what I know about the makeup of consumer lists, I’d have to say the issue was either at Yahoo or Gmail. Those two providers together make up over 50% of most consumer lists. Both companies have complex filtering processes that do not rely solely on IP address reputation, but look at content and a host of other factors.
Deliverability is critical for companies these days and even a short period of delivery problems can have serious financial implications.

Return Path on Content Filtering

Spamfiltering isn’t really about one number or one filter result, it’s a complex interaction of lots of different heuristics designed to answer the question: do recipients want this kind of mail?

Filtering is not just about spam

A lot of filters started out just as filters against spam. But over the years they’ve morphed into more general blocks against dangerous or problematic email. There’s a lot of crime and bad behavior on the internet, much of it using email as a conduit or vector. Filtering is so much more than stopping spam now. It’s as much, or more, about stopping crime.
Email filters are essential to protect us from scammers. Sometimes I forget this, and then I read about a grandmother getting swindled by a Nigerian scammer and ending up dead.
There are real consequences to poor filtering and there is real crime facilitated by email. It’s easy to forget this as we deal with the email that gets caught in filters when they shouldn’t.
Filters are one of the first lines of defense against online crime.
Not only does filtering stop crime, but they also keep email working. An unfiltered mail stream is an ugly, unreadable, unworkable mess.
