curl "$OE/senders/[email protected]" -H "$AUTH"{ "object": "sender_profile", "domain": "stripe.com", "about": "Stripe builds payment software for businesses that sell online, and operates worldwide.", "updatedAt": "2026-09-30T08:12:44.000Z"}A domain nobody has looked up yet is a 404, and so are personal mailbox providers such as Gmail and the domains of your own workspace.
