If I'm not checking whether the emails are duplicates or not (meaning duplicate emails are getting appeneded to the file)...does it matter that the files keeps getting bigger and bigger? Will that affect performance at all?

I was thinking of appending to the file and then when the time comes just hashing everything to find the unique emails.
