How to respond to this e-mail?

[0915reg]

Dear All:

When my boss or co-workers sent me an e-mail about work or whatever, what
should I simply write to tell them that I've received their information and I'll get on it?

Please give me any advice.

Regards.

Hi

In the case I just write 'OK' and/or 'I've got it'.
