Re-schedule the testing…

[hampeh]

Dear teacher and fellow friends,

I’m working on one network issue with my client. On our last discussion, they want to do some testing on the network. However, I didn’t agree with the date because I’m still waiting the investigation result from my technical support.
Today, I just received the investigation report my the technical support and want to let them know that they can do the testing.
Can I say something like this.

Happy New Year to all,

I just received email from the vendor and from the investigation, the network device seems working fine. Attached is the email from the vendor.
Please let me know if you have any question.

Thanks and best regards,
MyName
