Protecting customer data
There have been a number of reports recently about customer lists leaking out through ESPs. In one case, the ESP attributed the leak to an outside hack. In other cases, the ESPs and companies involved have kept the information very quiet and not told anyone that data was leaked. People do notice, though, when they use single use addresses or tagged addresses and know to whom each address was submitted. Data security is not something that can be glossed over and ignored.
Most of the cases I am aware of have actually been inside jobs. Data has been stolen either by employees or by subcontractors that had access to it and then sold to spammers. There are steps that companies can take to prevent leaks and identify the source when or if they do happen.
What is an email address? (part three)
As promised last week, here are some actual recommendations for handling email addresses.
First some things to check when capturing an email address from a user, or when importing a list. These will exclude some legitimate email addresses, but not any that anyone is likely to actually be using. And they’ll allow in some email addresses that are technically not legal, by erring on the side of simple checks. But they’re an awful lot better than many of the existing email address filters.
