Clean the entry list first
Every segment gets the same chance, so a name entered twice has twice the chance of winning. Paste the eligible entrants into the giveaway winner picker, read through for duplicates and delete the repeats unless extra entries are part of your rules. Take out anyone who did not meet the conditions before you spin rather than after, and rename entries to one consistent format so two spellings of the same person are easy to see. The list is the part people will question, so it deserves more care than the spin.
