About the @ sign
The @ sign is ubiquitous online. We use it and we don’t think about it. But the history of the @ sign is more complicated than we realize.

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.

One thing anyone collecting email addresses anywhere has to think about is address validation. How do you prevent users from typing bad addresses into your forms?
I ran into this yesterday attempting to take an online quiz. Before I was allowed to take the quiz, I had to provide my name, phone number and email address. Initially I attempted to use a tagged email address. This is one that delivers to my wordtothewise.com mailbox, but lets me identify who I initially gave the address to. The form wouldn’t let me give a tagged address “contains invalid characters.” Well, no, it doesn’t, but there are a lot of websites that think + and – and other characters are invalid.
So what did I do? I ended up using a yahoo address associated with my yahoo IM account. An account that may actually not be accepting mail any longer as I rarely log into it.
What did address validation get them in this case? Well, it got them an address I don’t read and may not even be active rather than the address I wanted to give them which would have delivered directly to my primary mail box. Somehow I don’t think this solution is really ideal for them. (It’s great for me, I’ll never know if they ever attempt to contact me.)
Coincidentally, UserGlue posted about email address validation and alternatives to “make them type their address twice.” (Do people do this? I typically cut and paste my address instead of retyping.)
