Joining my mailing list means getting:
You will only be emailed once a month (maybe twice but ONLY when something special is going on)
I promise: no spam, no invasion of privacy, no selling your info to pirates
Giving me your mailing address is completely optional. However, some freebies require me to ship things to you so in those cases it's pretty crucial. But again that information is completely confidential. A part from freebies the only thing I may send via snail mail would be invitations to show openings.
