You can send a receipt to your entire donor base. To do this, go to your Donors page and select the Fiscal Year End Summary button.
You will be taken to a page where you can view an example of what your year-end receipts will look like. You also have the option to make edits to this template, if needed.
Once you're satisfied with how the receipts will look, click the button labelled Send Receipts to all Donors.
Please note: It may take up to 15 minutes for all of your donors to receive their receipt.
