The copy-and-paste route is still there
Connecting a mailbox is optional. If you'd rather send it yourself, the drafted enquiry is still there to copy.
The email goes out from your real address, the venue replies to you, and the reply comes back onto the enquiry without anyone copying and pasting.
It lands in your Sent folder. The venue sees your own address and replies to it, threaded in your inbox like any other conversation — and that reply is captured back onto the enquiry, so the shortlist holds the answer. Unio only ever re-reads a thread it sent itself; it never lists or searches your mailbox.

Every phone field now carries a country code, which matters for a destination wedding where half the guests aren't dialling from India.
