Count Valid Phone Numbers And Email Addresses

I am looking for a formula to count the number of valid mobile phone numbers in a list and the number of valid email address in another list, 2 different formulas.

The mobile phone number formula would count the number of indervidual mobile phone numbers in a list that contain 077 and 078 and 079.

The email formula would count the number of indervidual email addresses in a list that contain ...........@..........dot com or .............@............dot co dot uk

Both lists may contain random junk text, like in the email list some one may have entered words like 'no email address' etc.
