Re-using Wondermail

[burgaz62]

The other day I pulled out my time version of pokemon mystery dungeon and started playing again. I had a whole box of random stuff, and while going through I found a couple of Sheets, with wondermail codes on them. I had marked the ones I had used, by drawing a circle next to them. I have not restarted my game since i have used these codes. When I put them in to my game, they still worked. i was wondering if anyone Knew the amount of time, or what you have to do to be able to re-use Wondermail Codes.

I don't think you can, but it has been rumored that if you do 20 other wondermail then you can reuse it, but honestly I don't think it works.( I did over 20 different ones and it didn't work) Just use the generator to make the wondermail for the reward you want.
