Quoting from [zachan]:
Dear friends.
I am a new sales in foreign trade. At beginning I had a lot of confidence and sent a lot of inquiries to buyers who post buying information here,but up to now I have recieved no reply yet. It make me miserable and dismay me very much. What can I do on such condition? Should I keep sending the people who did not take attention to me messages again and again?
It is thankful to dispel my problems
If you are responding to a Buying Lead that was posted and you are offering SPECIFICALLY what the person wants then a follow-up email 3 times in 2 weeks would be acceptable if it were me.
However, if you are responding with a product OTHER than what I posted about I may or may not respond.... If you keep emailing me I will become annoyed and add you to my BLOCKED list.
