The best way to contact Sadie is by emailing hello@sadiemccarney.com. An earlier incarnation of this website also included a contact form. In practice, this form served as a generator for emails from elderly widows urgently giving away $27 million (but only if Sadie sent banking information).
If you are an elderly widow giving away $27 million: please accept Sadie’s condolences about the death of your spouse and know that, while she is touched that you thought of her, she would likely squander the money on dames and horses.
