Having an alternative email account also insures you will keep the same email, even if you decide to leave your current ISP. Witness all the folks holding onto AOL accounts just to keep their AOL email address. Thank goodness at least that is free now.
AT&T's Spam Filter Gets A Bit Too Aggressive
You can certainly understand why ISPs offer spam filters. It's a service for users who don't want to be totally bombarded with spam. But what I've never understood is that these ISPs rarely give the user a chance to circumvent the spam filter themselves. If most people want to ignore it and assume all spam is spam, then so be it. But what if some users want to make sure no legit emails are getting through? Witness the latest chatter about AT&T's "upgraded" spam filter that is apparently eating up a ton of legitimate emails with no indication to the receiving party. It's surprising that AT&T would do this, knowing (as it must) that back when Verizon became too aggressive with its spam filters, it lost a class action lawsuit and had to pay out a few million dollars to annoyed users. Either way, it's a reminder not to use your ISP's email solution.
