1. After receiving such an inquiry, I know that the other party is in this industry, but you don't have the product he wants. Actually, there is still the possibility of cooperation. So the idea is right. Say "sorry, we don't have this" to the other person first, and then say "actually, we have something you might be interested in".
From the second half of the email, I can't feel your strong desire to do business with him, it's very dull. Language is not easy to arouse customers' interest in your products.
It is suggested to delete the third paragraph. Sorry to tell you. Direct, but it's not a clever mistake. The following is some information about this product. Don't say sorry easily. More than one customer once said to me, "China people like to say sorry, but they don't often need it." In their view, it must be a mistake to be stupid before saying sorry. It is not a mistake that your family doesn't have the products he wants, but it is a pity at most.
4. By the way, people feel that your praise is from the heart or what value it has to them. They might think: oh, well, not bad.
5, some grammatical errors, such as
Add may before working hours;
Its work changed its work, and supply changed supply;
The warranty of faucet is 5 years, and the led display is 2 years. We provide a five-year warranty for the faucet and a two-year warranty for the monitor.
Closed to closed.
Looking forward to you. Change it to your reply.
