store emails in two different tables

[$php_mysql$]

friends how can i store email id of user in 2 tables? in my table one user can post same email many time, but in my tbl2 i want to make it check if email exist i also make the row unique in tbl2 for email

 

 

function insertData($postData) {			

//trying to check if email not exist in tbl2 then store the email else go below and keep adding same email as many times,, the function ifEmailExistschecks for existence of emails
  
if(!ifEmailExists($postData['email'])){
$sql = " INSERT INTO tbl2 SET
		email 	= '".$postData['email']."'
		";
		executeSql($sql);

}else{		

//in below same email can be store as many times

		$sql = " INSERT INTO tbl1 SET
		title	= '".$postData['title']."',
		image	= '',
		description	= '".$postData['description']."',
		time	= '".time()."'
		";
		executeSql($sql);
		}else{			
		$sql = " INSERT INTO tbl SET
		title	= '".$postData['title']."',
		image	= '".$resize_rename."',
		description	= '".$postData['description']."',
		time	= '".time()."'
		";
		executeSql($sql);						
		}
}

 

this code stores the email for first time but when i try to enter data again i get Duplicate entry '[email protected]' for key 'email'

 

what is the solution for this?
