I am trying to find my sky email service too as I have not used it before.

HOwever when I go to the sky portal at Sky Broadband - Home and log in it then just takes me to the mysky page.
There is nothing there for email except a black tab at the top "email and tools".
however when I click on that it says:
Hello. You've come to the right place for new Sky Email and Tools, but you're a little bit early.

We're upgrading everyone in stages to make sure we do it securely. Your upgrade hasn't happened quite yet but you can still carry on using your original email service and getting your emails by logging onto Sky Broadband - Home. Rest assured we'll switch you soon and we'll let you know the minute it's done.
which then links back to the my sky page?
