How to contact right customers through Electronic Commercial Websites, such as: Alibaba.com.

I have some suggestions for you:
1) First, you should double check if the marketing method that you are using (i.e broadcasting letters) is suitable for your product/service type?? Remember that, for some specific products/services, this way of marketing is useless. In this case, human face-to-face approach is prefered.
2) Second, you need to make sure that the receivers are your target customers. You send to the RIGHT PEOPLE.
3) Third, check whether they get your letters at the RIGHT TIME, they get when they really need information. Time of the week must be considered too. My experience says that Friday is not a good day of the week for letter's arrival (people are quite lazy this day to read it ;-)
4) You should have a website with "easy-to-remember" name. E.g: DuLichGiaRe.com, DuLichKhuyenMai.Com ... are very good manes for a Tourism company. You should do the same thing for your own.
5) A small sticky decal with your website address and Tel phone should be sent together with your marketing letters. Suugest yiur customers to paste the decals on his telephone set or wall. Make sure that they know how to contact you when they need it. A destop calendar with your company info is also a good idea
6) The design of your letters and brochures are so important

PLEASE NOTE THAT YOUR SALES CAN NOT GROW IMMEDIATELY RIGHT AFTER SENDING MARKETING LETTERS. THIS IS A SUFFERING WORK AND BE PATIENT. GOOD LUCK

Thanks so much. I will review back and make several new ideas
