It is going to be close between my gmail (I was invited during the beta in 2004) and my bank which would have been 2002/2003 timeframe but I can’t remember for sure.

I can remember earlier accounts like deadjournal, Hotmail, something awful, but I don’t use those anymore.

I'd forgotten about gmail being in beta like that — hardly surprising, of course! My welcome email confirmed it; it begins "First off, welcome. And thanks for agreeing to help us test Gmail." Dated June 2004.
