一般按照工作的场合需要不同的方式,不过如果只是需要跟大家寒暄几句的话,觉得直接去面对面的交流更有效,更容易给人好的印象。不过说道你需要一个样板,可以是这样:
Dear colleagues,
I am xxxx. I will be starting my job at xxx department from today. It was a honor to join this wonderful company. I am excited and looking forward to work with you all and to contribute to the company as a team. Wish you have a great day!
Best regards,
