mysql: min value per group

surprisingly, to find the min date per company, which is a super basic query, on mysql you need to do a complicated query. 

SELECT a.id,
       a.company,
       a.email,
       a.custom_last_email
FROM leads a
         INNER JOIN
     (
         SELECT company, MIN(custom_last_email) mindate
         FROM leads
         GROUP BY company
     ) b ON a.custom_last_email = b.mindate and a.company = b.company
GROUP BY
a.company
