I signed up but in the Terms Of Service, it requires that you put your address and phone number on each email you send out. I don't have a brick and mortar store. I am an author and sell through Amazon and many other places. I wasn't planning to do e-commerce, I just wanted to create a mailing list. I'm scared to put my home address and home phone number here, so I deleted my account. Can't comment on their services or anything, since the TOS spooked me!Apparently this is due to Anti-Spam Laws in the US, that you have to put an address. So I guess I'm not having a mailing list, period. I can't afford to establish a 'business' address, I only have one.
