My professor sent me an email. At the end of the email he asked for receipt acknowledgement.

Please should I send the receipt acknowledgement separately and then answer the email or just answer the email, giving that I will do it instantly?

    If you can answer immediately, do so. Else, acknowledge with a estimated date for an answer.

Probably best to acknowledge first anyway, since there is inevitably some risk that "instantly" becomes less instant...

If you can reply instantly, that covers the request for an acknowledgement and you don't need to send two separate messages.
