Well, you will need to store if you already sent an email that day, but other then that

SELECT DATEDIFF( CURDATE( ) , expire ) AS daysleft, id, user, email
FROM something WHERE 
daysleft='30' 
OR daysleft='60' 
OR daysleft='15'
OR daysleft='7'

something along this line could work, then you say like You have $data->$daysleft left.
