元旦后 复工第一天 第一封邮件 一般跟老外说什么

Dear xxx,
送上新年的祝福诸如：Happy new year and best wishes for the year to come.
如果有订单，那么可以表达一下对去年合作的谢意等等：I want to take this opportunity to thank you for all the help and support during our cooperation in the past 2014.....
然后告诉一下他你们已经正常开始工作，保持沟通：Thanks to note we have resumed to work from Jan 4th. If you do have any enquiry, we will be at your full disposal.  Keep in touch.

Thanks and best regards.
......之类之类
