已经使用计数和分组依据时的不同值

Question

This is currently the SQL query I am using:

SELECT DAY(time), count(id) 
FROM users 
WHERE time >= now() - INTERVAL 7 DAY 
GROUP BY DAY(TIME) 

But it includes repeated email values. How can I get the count by day for only unique email address entries?

Thanks

SELECT DAY(time), count(distinct email) 
FROM userWHERE time >= now() - INTERVAL 7 DAY 
GROUP BY DAY(TIME)
