I've never seen the 8 of Swords in relation to the internet but the 8 of Wands sometimes can indicate it.
Like I said 8 swords = inbox, since a message is "incased". Also, I get this too for packages that is "tightly" wrapped with tape all over it. It is like the package is tied up, or bounded aka imprisoned by tape, ribbons, or gift wrap.
For me, I rarely get 8 wands for emails, mail, etc. Maybe the rare occassion when a letter that I am sending (not anyone sending to me) is going to be taken to the post office for air delivery cross country or international where 8 Wands = airplane or air flight.
I think why 8 swords = email for me is that a message is trapped in your computer until you open it up with an username and passwords where no one can open it up but you. So the message (email) is like a tied up victim waiting to be set free by you logging in your computer/email.
