The leak

A guest has a great night, tells you so on the way out, and you never hear from each other again. Not because they didn’t like it. Because life is busy and you had no way to remind them you exist.

The guests you already have are the cheapest guests you’ll ever get. But you can only invite them back if they’ve said you can.

What it costs you

Yearly value = people on your list × share who come back once more × guests per visit × contribution per guest

Worked example · Mirela is fictional

Mirela collects 1,200 opted-in guests in six months. If 1 in 10 comes back one extra time a year, with one friend:

1,200 × 10% × 2 guests × $38.50 = $9,240 a year

Row	Contribution a year
1 in 20 come back	$4,620
1 in 10 come back	$9,240
1 in 5 come back	$18,480
Cost of the list	A monthly email

Contribution per guest is the $38.50 from Chapter 6: spend minus food and drink. A list costs nothing but a monthly email and the care to send only what’s worth opening.

Collect permission, not just emails

Only email people who said yes. It’s the law in most places, and it’s the only list worth having: people who asked to hear from you open your emails. Email is the easy start. Marketing texts carry stricter consent rules, so check them before you text anyone a promotion.

Ways to ask that don’t feel weird:

At booking. Check whether your reservation platform can ask guests to opt in to your updates. Turn it on.
On the check presenter. A small card with a QR code: “First to know about new dishes, special dinners and holiday bookings.” It links to a simple sign-up form.
From your staff. One natural line when a table says they loved it: “We send one email a month, mostly new dishes. Want it?”
On your website and Instagram (Chapter 9).
From private event guests and gift card buyers, who already chose you.

Give people a reason that isn’t a discount: first access to holiday reservations, an invitation to a special dinner, a note on their birthday.

The fix

Pick a free email tool. Several have free plans for small lists. Or use the email marketing in your POS or reservation system, if you already pay for it.
Make a sign-up form with three fields: first name, email, birthday month (optional). Add a clear line: “One email a month. Unsubscribe anytime.”
Put the QR code on every check presenter and the link in your Instagram bio. Prompt 1 writes the card and the staff line.
Set up a welcome email that goes out automatically when someone signs up.
Send one monthly letter. One thing worth coming in for. Prompt 2 drafts it in five minutes.
Every quarter, invite back the quiet ones. If your reservation system shows who hasn’t booked in 90 days, send them Prompt 3’s note. Only to people who opted in.
Count what comes back. Track bookings from emails with a mention line (“tell us you saw this”) or a unique booking link.

Worked example · Mirela’s monthly letter · fictional

Every Tuesday this month, the kitchen makes one pasta we don’t put on the menu. This week it’s pici with duck ragù. It comes with Tuesday Supper, three courses for $39. Book at mirela.nyc. See you soon. — Mirela
