Send to anyone now covers both environments, and held mail gets a Deliver button
Turning on Send to anyone in Settings > Email now applies to your Development and Production computers at once. Before, only the published app was switched on, so a test send from the editor could still be held while the page said delivery was live.
Mail that was held before you switched it on no longer sits there: every held address now shows a Deliver button as soon as your domain is verified and Send to anyone is on, including addresses that were never added to your verified recipients.
Your sending domain verifies within seconds of the records going live, with nothing to click. The assistant can check a domain for you too, and reads each email under the computer it came from.
Adding a customer's address to Verified recipients now warns you first: that list is for your own inboxes, and each add sends the person a permission request. Customers are reached through your own domain.
