What is the difference between a notification sent to me, the Account Holder, and the confirmation sent to a third party for the third party’s contribution?

A notification is sent to the primary Account Holder as an alert that a third-party contributor has made a contribution to Fidelity Charitable that was allocated to his/her Giving Account. A confirmation is also sent to the third-party contributor to serve as written acknowledgement for use to substantiate their charitable deduction for tax purposes.
