I am having issue get started with email marketing. I am deciding to use between aweber or get response , aweber if i am not wrong, have to pay monthly for the services + pay for number of subscribers getresponse is just pay based on number of subscribers monthly, which is cheaper? I am having issue with the address part, when you send out an email, under can-spam act , address is needed. I do not wish to show my personal address, if use p.o box , it need to be u.s and not from my own country? I am not sure with the u.s p.o box and will never check the mail there. Other than p.o box, what other options do i have?
