if you are the client

If you were a clients, what kind of business email would you like? For almost a month, I have been trying to develop ties with new clients and have been sending many many email to the potential clients. I mainly introduce our products to them, but unfortunately, few of them give me feedback. what problems do I have with my emails? Are there any tips? I would like to ask help from you. Thank you.

were a- because it is an imagined situation. Eg; if you weren't at work what would you do.

have been- because the action began in the past and continues infer relevant in the present.

I do not think Email is an effective marketing tool to promote your products or you . I would suggest you might build a formal website to promote your products . I am really curious what kind of products you are selling . I am intereted in your products as you seems so confident of your products .
