You could create a second email address to give out in these situations. But then that's another inbox to check and manage.
If you've ever dreaded giving out your email address, look no further than MailDrop. It's a site that lets you create a fake, temporary and disposable email address to ensure your personal security.
Better yet, you can make up whatever email address you want to give out. You could be something simple like nomorespam@maildrop.cc, or pay homage to your favorite internet sensation - dog and cat beards - with dogbeardchamp@maildrop.cc.
So, the next time you see "Please enter your email address to continue," put in your new MailDrop address instead of your real one. When the time comes to check that inbox, just enter the address at the top right hand side of the MailDrop page.
It's also important to note that every email address is a public inbox. Anyone who knows your address could check your email. Make sure you don't use MailDrop for any private or sensitive emails.
