Before GMail a typical webmail provider gave you so little space that deleting irrelevant e-mails was standard practice; otherwise your inbox would soon fill up.

Frankly, I had to delete my e-mails on school Linux server AND not so long ago, on company mailbox. Yes, this is ridiculous and yes, it happens.

I use a 503(c) service for email, the only thing is that they rely on dontations, so the more space I use the more it'll cost them. So out of being curteous to them, I delete any unwanted email. One other reason I delete email is because I like having a 'clean' inbox.

But despite all of that, it's really Skype's fault for assuming that a user will keep randomly chosen, arbitrary data like that. Not all of us have photographic memories, so the vast userbase, as a result, will have great difficulty in deleting their account. There's also a very high probability that it's done by Skype deliberately, to stop people deleting their accounts (Because data mining is 'phun'!)

Yes.

I have zero reason to keep a Skype welcome email. I hate clutter - even digital clutter.
