You have to use the link provided in the email, those offers aren't available under "My Account". If you no longer have the email you can contact CS and they will help you.
Can I ask when did you receive the email? I'm still waiting... =/
£21 a month for 12 months + 1 month free boost at https://www.nowtv.com/watch-f1-online. This did not appear in my offers, nor email.
