Can you please provide me with the phone number and email addresses of these five customers?
SELECT T1.customer_phone, T1.customer_email FROM customers AS T1 JOIN mailshot_customers AS T2 ON T1.customer_id   =   T2.customer_id where T2.outcome_code  =  "No Response"
phone number refers to customer_phone; email addresses refers to customer_email; these five customers are identified by joining customers table with mailshot_customers table based on customer_id and filtering where outcome_code is 'No Response';
