Were can you send manga artists PEACH-PIT fan mail?

Answer 1

This is the official web site of Peach-Pit.

It says news about their works are published on the 1st of every month.

Also says here that all fan mail should be directed to the respective serializing magazines (presumably in Japan)

These are the details for 1 of their series:

Zombie Loan: published in 月刊Gファンタジー Monthly G Fantasy

1st row - Your own name

2nd row - your email address

3rd row - select from the drop down menu who you wish to send to, Peach-Pit is shown

clearly in English there

4th row - for names of other artists

5th input box - your comments
