Find your receipt: Your most recent emailed receipt will include a "manage your subscription" link in the paragraph that begins "This is a monthly donation …" Click the link and you'll go to a page titled "Subscription," seen in the screenshot below. Go to the row labeled "Credit card" and click the "Update" button. Make your change and click the "Save" button and you're done!
If you are not getting emailed receipts for recurring donations, first check your spam or junk mail folder – search for anything with the word "Pledgeling."
If you still can't find the receipts, open a support ticket using the "New Support Ticket" button near the top right of this page. Since the reason you're not getting receipts is probably because of a problem with the email address we have on file for you, please double-check that you enter it correctly, and include the date and amount of the charge, and the last four digits of the card being charged so that we can quickly find your recurring donation.
