翻译 这样写行不行

you can write as this:
long time no contact,I'm so glad to receive your e-mail.

Having not contacted you for so long time, i am glad to receive your mail.

It is happy to receive your email,I has not contacted with you for a long time.

...I have not contact with you for a long time.

这是典型的中国式英语，当然...是不行的，下面请参考：I'm glad to have received your letter, I miss you so much though it's a long time since i wrote to you.
