Just ignore the @gmail.com / yahoo.com anti-user bandwagon.
Especially the tool with TwilightFan91 moaning about e-mail addresses.
Give me a break.
I have to agree. I've been a professional software developer for 17 years, and I've never encountered an HR person that had a problem with an applicant's email domain.
I use gmail, and here is why:
In the last 15 years or so, my ISP email address has changed no fewer than 5 times.
Example: Back before broadband, I used a local internet provider called "Neosoft". My email address was @neosoft.com. Internet America (@airmail.net) bought them out, and my email address changed to (@airmail.net, which, while is in fact an actual ISP, because it has the word "mail" in the name, it sounds like some of these guys would immediately trash it). It's possible that the neosoft.com address gets forwarded to the airmail.net address.
Unable to get cable internet in my area, I upgraded to DSL, with another local provider (SBC did not provide service my area), and my new address became "@mylinuxisp.com".
Later, Time warner cable started to offer cable internet service for about half of what I was paying for DSL, so I upgraded to that. My new email address: "@roadrunner.net".
A few years ago, Comcast took over time warner's presence in my area, and now my ISP-based email address is "@comcast.net" (I think, I stopped using my ISP-based email address years ago, because it was such a pain to propagate the change to everyone I knew, or paid bills with, etc...)
I got my google mail account pretty early on, back when it was invite-only, and the domain name (gmail.com) is very unlikely to ever change. This means that no matter where I live, or which internet provider I decide to go with, my email address need not change. If google charged me a small fee, I would gladly pay it, for the convenience of not having to deal with changing my email address.
Perhaps now that "anyone" can register for a gmail account, there is a negative connotation developing around it, but this is the first I've heard of it.
I tend to agree with Killbilly and the others. You guys that filter based on 'free' email service are likely throwing away perfectly good candidates, possibly with perfectly good reasons as to why they have chosen a particular email provider (free or not).
