I’m writing you this email just to ask whether there’s any problem with the **we supplied. As we were told by an American guy named Michael that you have changed to another company due to quality issues. We felt really confused and surprised about this as we’ve been enjoyed working with you so much during the past one and half year and feedback from you about the last two orders seemed to be ok except for some minor problems.I know we have no right, position or whatsoever to question you, and if you really have swaped to another supplier, we also need to respect your decision, but being responsible for our products is something we need to do as a supplier. So if there’s any quality issue with**, can you please let me know? We will see what we can do to improve and avoid these problems in the future. And if there’s any other issues besides quality problems regarding our cooperation, please also let me know, we will do everything we can which is beneficiary to our relationship in the long run to serve you better.6.联络同事之前的客人Dear xx,In order to deepen our cooperation and explore more potentials,I am assigned to be good following up your valued account by our top managment from today on.I have already studied alll your datebases and reviewed our current products range, I would like to propose attached new products for you, we were not sure if those products would fit into your market or not, in that case, our managments are happy to offer you free samples for your internal meeting,if your meetings would be postive,we could arrange MOCP up samples under your artworks for further comments.Awaiting your inforamtion.Thanks.7.看老外辞职了是怎么写邮件通知partner（里面很多句子能带给人灵感）Dear allI hope my email find you all wellI would like to take this time to sincerely thank you all for your support during my time here。
