What email system are you using. I use Yahoo mail and if I go to Yahoo.com from the browser it looks just like the Yahoo page on my computer if you select the "clasic site" feature at the bottom. I also have the Yahoo Mail app and I think there is an Edit button you hit and then you can choose to delete, forward, or what.
I just logged in to my dads hotmail account and opened an email. All the way at the bottom of the email are buttons to forward, reply, etc.
