Answer 1

Use this query:

SELECT email, COUNT(*) AS nb_emails
FROM your_table
GROUP BY `email`

It will return for each email in your table the number of associated records.

If you are using mysql_* functions, you may fetch all values using that code:

$sql = "SELECT email, COUNT(*) AS nb_emails
          FROM your_table
          GROUP BY `email`";
$res = mysql_query($sql);
while($row = mysql_fetch_assoc($res))
{
    // do something with the values of the last fetched record. The values are stored in $row['email'] and $row['nb_emails']
}

Note: Use of the MySQL extension is discouraged. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information.
