Help! My e-mail Icon has disappeared from the front of my iPhone (7). Where has it gone & how can. I get it back??

That link is out of date, on more recent versions of iOS you can delete built in Apps.

If you head to the App Store (which is the one app I think you can't delete) and search for "Mail" you should be able to find the Mail app again and get it back on your phone.
