Mailbox
This is what your business sends by itself — email and text, side by side. A form gets filled in and the welcome goes out on both. Work is marked done and the thank-you follows. The evening before an appointment, the reminder goes out on its own. Nobody has to remember any of it.
Nothing here reaches a real person. There is no mail account and no phone line attached to this demo, and no code left in the build that could talk to either — every message is delivered to this page instead, rendered exactly as its recipient would see it. Texts only go to people who ticked the box; open one and it says what it cost to send.
No message matches that filter.
The same mailbox, two trades. A barbershop's is almost all review requests — one a day, each going out the morning after the cut, which is how a shop gets from forty Google reviews to four hundred without anyone asking in person. A lawn crew's is almost all invoices and spring follow-ups to last year's customers, sent in February when the phone has not rung since October.
And the same split, by channel. The reminder is a text and never an email, because nobody opens an inbox on the way to work. The review request and the follow-up are emails and never texts, because those are the two a person replies STOP to — and a shop that loses the channel over a coupon has lost the one it needed for the reminder.
