给加拿大教授的邮件，急急急，帮忙翻译一下吧

Dear Prof. __:

I apologize for the late reply at the end of the month. I couldn't find your email address since I used classnet the last time I emailed you. I only found your email address when I was doing my course selections this time. I was wondering if you could spare some time for me so we could meet up. Please text me at _______.

Regards,

你跟那教授很熟还是不熟啊- - 最后给你改了……

Dear Professor **,

Sorry for the late reply, but I did not find your email address since I used the classnet to send you the email last time. However, I found it when I was selecting courses in class.

I am looking forward to meeting you at your convinience. If you have my phone number, please text me any time.

Best regards,

Yours sincerely,
****

“上次是用classnet发的邮件，所以没找到你的邮件地址”是啥意思？
