To "notify" is to inform someone of something: there is a provider of information and also a receiver. But not every communication notifies. A notification is an authoritative statement that is not subject to further argument -- or even discussion! Within a corporate hierarchy, it may be an order or direction from above, or a resignation from below.
To "note" is either
- to state something (there is not necessarily a receiver of information) or
- to receive information from someone.
It is best not to use "note" as the main verb of acknowledgement.
In the context of electronic mail, therefore, the receiver may certainly use a phrase such as
Thank you for your notification. I note that you have particularly emphasized A and B and C....
It is seldom a notification, however, that the receiver must acknowledge. It is usually far better to say something like the following:
Thank you for your input. As you have aptly noted, ...
I am grateful for your guidance.
Your direction is both helpful and welcome.
I acknowledge your suggestion. Our present circumstances, however, make it imperative instead to choose the following course of action... [Be very careful with
acknowledge. This word is a brush-off. You may need to say it, but be sure you know what you are doing.]
