Tip! Always send your address in an email even if you are only inquiring about where to send a request. I've emailed quite a few celebrities who didn't respond to my email but actually sent an autograph just from my request for an address!

Jim Davis (Garfield author)
Martina McBride
Jimmy Cricket
Dale Winton
Jonathan Ross
David Cassidy (was a pp though )

Hard to say, I'm afraid it may matter in some places... Actually it depends on the place You're sending Your mail - some e-mails have antispam filters, and Your message without a subject could get lost there...

Good luck though!

I doubt it matters {thumb2}

If I sent an e-mail about autograph requests, and I didn't put a 'subject' when I sent out the e-mail, would it matter? I didn't give them my address, I was inquiring about where to send my request, so I was expecting a reply.
