What do you use mail for in Pokemon Gold?

Answer 1

You can place messages on them and have a Pokemon hold them.

When you trade with somebody, they'll get both the Pokemon and the mail.

It's like giving messages with trading Pokemon.

That's a waste of time as you have to be so close to trade that you could tell them about it so that removes the effectivness of the mail although they do make good note takers

It's a very good point, it is pretty useless, but in the time it was nice to see.

I think it was just another way for Nintendo to show off new things in PKMN.

Yea that IS true The most Important reason for mail is So you know what it is. The trainers you meet and people you meet might give you mail or ask you to give someone else mail. So you can buy mail i's for no real reason though so It's pretty useless as previously stated~Gracygoo
