Most bulk email marketing services offer a free option for small mail-outs (for example, 250 emails or less, once a month); however, I don't think a free option is popular for 1000 or more emails.

You seem to be on the right track. I gave your code a quick look over and a few things caught my eye: 1) You use a variable called "array_size" in the for loops, but I don't see it defined beforehand. 2) Instead of using the magic number 5 throughout …
