Select Distinct between two tables inner join

Question

I have table 1 which contains unique values and table 2 which contains multiple values for the same email. What I want to do is select the first value of 'id' - table 2 contains a number of ids and matching emails

SELECT DISTINCT 
table1.email,
table2.id FROM
table1
INNER JOIN users ON table1.email = table2.Email

the problem is the output needs to be unique - i.e. one ID - the first one from table2 that is associated with a given email - currently we're getting multiple results - no unique or distinct values.
