Email opt in that guests do not regret

The wording and the promise beside the box, and why telling guests how often you will write to them makes the box easier to tick rather than harder.

A guest books a table online and, near the bottom of the form, sees a box: "Keep me updated." They tick it, because the meal sounds good and the restaurant seems nice. A week later the first email arrives, then another, then three more in a fortnight, each with an offer. By the end of the month they have unsubscribed, and they think a little less of the restaurant. The email opt in worked. The guest regretted it.
Most venues think of the opt in as a number to grow: more ticks, a bigger list. But a list full of guests who regret joining is worse than a smaller one. They ignore the emails, unsubscribe or mark them as spam, which harms the emails that reach everyone else. The aim is an opt in that guests are glad they gave, because what they receive is what they were promised.
This guide covers what the box should say, the promise to make beside it, why saying how often you will write helps, how to confirm consent, where to ask and how to keep the promise once guests have joined. Every venue and figure in it is an example.
What an email opt in is
An email opt in is a guest's choice to receive marketing emails from you. It is different from the emails that come with a booking, such as a confirmation or a reminder, which the guest needs whether or not they want marketing. The opt in is about everything else: news, menus, events, invitations.
The idea, often called opt-in email, is that the guest actively agrees rather than being signed up by default. For a restaurant, that is not just a rule to follow. It is the foundation of a list that works, because guests who chose to hear from you are the ones who read what you send.
Why regret matters
A guest who regrets opting in does more harm than one who never joined. They ignore your emails, which tells email providers your messages are not wanted. They unsubscribe, which shrinks the list. Some mark your emails as spam, which can push future emails into the spam folder for everyone.
So the quality of the opt in matters more than its quantity. A venue with a thousand guests who are glad to hear from it will get more bookings from its emails than one with five thousand who feel they were tricked into joining. Our guide to email deliverability: why your mail goes to spam covers how unwanted mail affects every send.
The box and the words beside it
The box itself should be unticked, optional and separate from anything the guest must agree to in order to book. A guest should be able to book a table without joining a list, and joining should be a clear choice they make.
The words beside it do most of the work. "Keep me updated" is vague. "Send me news about new menus and events, about twice a month" tells the guest what they will get and how often. Clear words get fewer ticks from guests who were never going to read the emails, and more from those who will.
Say how often you will write
The most common worry about joining a mailing list is being flooded. Saying how often you will write answers that worry before the guest has to think about it: "about twice a month", "once a month, with the new menu", "only when something is worth knowing".
That small promise makes the box easier to tick, because it removes the main reason for saying no. It also sets a standard you have to keep. A venue that promises twice a month and sends twice a week has broken its word, and guests notice. Our guide to email frequency: how often is too often covers how to find the right rhythm.
Say what they will get
Tell guests what kind of emails they will receive. New menus, seasonal dishes, events, early invitations to tastings, the occasional quiet-night invitation: whatever you actually plan to send. Be honest, and be specific enough that the guest can picture it.
Avoid promising "exclusive offers" unless you really intend to send them. A guest who joined for offers and receives news about the new chef feels misled; one who joined for news and receives a stream of offers feels the same. Matching the promise to what you will send is the simplest way to avoid regret.
Say who it is from
Make it clear who the emails will come from. A guest who books at a neighbourhood bistro expects to hear from that bistro, not from a group of twelve restaurants they have never visited. If the emails will come from a group, say so beside the box.
A name helps too. "News from Maria and the team at the bistro" is warmer than a business name alone, and it sets the tone for emails written in a real person's voice, which are the ones guests read.
Make leaving easy
Tell guests they can leave at any time, in one click. It seems strange to mention leaving while asking someone to join, but it reassures them. A guest who knows they can unsubscribe easily feels safer saying yes.
Then make it true. Every marketing email needs a clear, working unsubscribe link, and an unsubscribe should take effect without the guest having to log in, explain themselves or confirm three times. Unsubscribes are a normal part of any list. Making them difficult only turns them into spam complaints.
Marketing consent that holds up
Good marketing consent is clear, specific and recorded. The guest chose to tick an unticked box, they knew what they were agreeing to, and the venue can show when and where they agreed. Consent bundled into booking terms, or implied by the act of booking, is weak at best.
Rules on marketing emails differ from country to country, and some allow businesses to email past customers in limited ways. The safest habit, and the one that builds the best list, is a clear box the guest chooses to tick. Our guide to marketing consent, collected so it holds up covers the details.
Confirming by email
A confirmation email, sent after the guest ticks the box, asks them to confirm that they really want to join. It is sometimes called double opt in. It catches mistyped addresses, stops anyone signing up someone else and gives the venue clear evidence of consent.
Some guests will not confirm. That is fine: a guest who will not click one link to join is unlikely to read your emails. Watch the share who confirm, though. If it is low, the confirmation email may be landing in spam, or the wording beside the box may be attracting ticks from guests who are not really interested.
Where to ask
The best places to ask are the moments when a guest is already interested: when they book, when they are enjoying the meal, when they ask about events or the new menu. A box on the booking page, a code at the table and a friendly mention at the end of a good evening all work.
The worst moments are when a guest is busy or impatient: at the door on a busy night, while they are paying in a hurry. Our guide to loyalty sign up: the thirty seconds you get covers timing in more detail.
Building an email list slowly and well
Building an email list is a slow process, and it should be. A list that grows by a few dozen engaged guests a month becomes, within a year, one of the venue's most valuable assets. A list that grows quickly through pressure, tricks or bought addresses becomes a liability.
Focus on the guests who have actually been in and enjoyed it. They are the ones most likely to come back, and the ones whose opt in you can trust. Our guide to building an email list from the room you have covers how to grow it from your own guests.
What not to do
Some practices build lists quickly and damage them for good. Pre-ticked boxes. Consent hidden in booking terms. "By booking, you agree to receive marketing." Bought lists. Contacts imported from an old system without checking whether they ever agreed. Signing up everyone who has ever booked.
Each one fills the list with people who did not choose to be there. They ignore the emails, complain and unsubscribe, and in many places these practices also break the rules. They are never worth it.
Keeping the promise
The opt in is a promise, and every email after it either keeps it or breaks it. If you said twice a month, send twice a month. If you said news and events, send news and events. If you said the emails would come from the owner, have the owner write them.
Keeping the promise is what stops guests regretting their choice. A guest who receives exactly what they were promised, at the rhythm they were promised, has no reason to leave. That is why the words beside the box matter so much: they are the standard every future email is held to.
The first email after opt in
The first email after a guest opts in sets the tone. Send it soon, while they remember joining. Thank them, remind them what they will receive and how often, and give them something worth having: a note about the dish everyone orders, the next event or the season's menu.
Keep it short and personal. A welcome email that reads like a brochure tells the guest that the emails to come will read the same way. One that reads like a note from a person tells them the opposite.
Guests who opt in at one venue in a group
In a group of venues, be clear about what a guest has joined. A guest who opted in at one venue has agreed to hear from that venue, unless the box clearly said otherwise. Sending them emails from every venue in the group breaks the promise they thought they were making.
If you want guests to hear about the whole group, say so beside the box, or offer a separate choice. And when several venues write to the same guests, agree how often each one sends, so the guest is not receiving four emails a week from four places.
When guests change their minds
Guests will change their minds, and that is normal. A regular who has moved away, a guest who joined for one event, someone whose inbox is simply too full: all will unsubscribe sooner or later. Honour it at once, without fuss.
Do not try to win them back with a "sorry to see you go" email, and do not keep sending through another route. A guest who unsubscribed cleanly may still come in for dinner. One who felt they could not get away may not.
Re-confirming old lists
Many venues have old lists, collected years ago on paper, at a previous system or with a vague box. Some of those guests agreed clearly; many did not, or have long forgotten. Sending marketing to them now risks complaints and spam folders.
Consider a single, polite email asking whether they would like to keep hearing from you, with a clear button to confirm. Keep those who say yes, and retire the rest. It shrinks the list, but what remains is a list of guests who chose to be there.
Measuring opt in
Measure the opt in with a few simple numbers: how many guests are asked, how many tick the box, how many confirm, how many unsubscribe after their first few emails and how the list grows over time. Together, they show whether the opt in is attracting the right guests.
Look for warning signs. A high tick rate with a low confirmation rate suggests the box is being ticked without much thought. A rise in unsubscribes after the first email suggests the welcome does not match the promise.
Unsubscribes are a signal
Unsubscribes are not failure; they are information. A steady trickle is normal. A sudden rise after a particular email tells you that email broke the promise: too salesy, too frequent, not what guests signed up for.
Look at which emails cause the most unsubscribes, and learn from them. A list where unsubscribes stay low is one where guests are getting what they expected, which is the best sign that the opt in was honest.
The tone of the request
When staff ask guests to join in person, the tone matters. A relaxed, low-pressure mention, "if you would like to hear about our events, there is a code on the table", works far better than a scripted pitch. Guests can tell the difference between an invitation and a sales target.
Never make the request a condition of anything, and never ask twice in the same visit. A guest who says no should leave with exactly the same warm goodbye as a guest who says yes.
Opt in for guests who book for others
When one person books for a group, only that person can opt in for themselves. Their companions have not agreed to anything, even if their names are on the booking. Do not add the others to the list because one person ticked the box.
If you would like to hear from the whole table, invite each of them to join for themselves, with a code at the table or a word at the end of the meal. Each guest who joins that way has chosen it, which is the only kind of opt in worth having.
Opt in at the table
Guests at the table are often the most willing to join, because they are enjoying the evening. A small card or a code on the table, with the same honest words as the booking page, lets them sign up in a few seconds without a member of staff having to ask. Keep the card simple: what they will receive, how often and that they can leave at any time.
The same confirmation applies. A guest who scans a code at the table should still receive an email asking them to confirm, so the list stays as clean as the one built from bookings. And a guest who joins at the table has just had a good evening, which makes the first email after it easy to write: thank them for coming, and tell them what is next.
A worked example
An invented wine bar has a booking form with a ticked box reading "Keep me updated" and a list of several thousand guests, most of whom never open its weekly emails. It changes the box to unticked, with the words "News about tastings and the new wine list, about twice a month. Leave any time." It adds a confirmation email and starts sending every other week, as promised.
Fewer guests tick the new box at first, but far more of them confirm and read the emails. The bar also sends one email to its old list asking guests whether they would like to stay, and keeps only those who confirm. The list is smaller, but more guests reply, unsubscribes fall and the tasting evenings fill from the emails alone.
Common mistakes
- A pre-ticked box, or consent hidden in the booking terms.
- Vague words like "keep me updated".
- No promise about how often you will write.
- Promising news and sending offers, or the other way round.
- Sending more often than you promised.
- Emails from every venue in a group to guests who joined one.
- Unsubscribe links that are hard to find or slow to work.
- Old lists mailed without checking whether guests ever agreed.
Where servearound fits
In servearound, the booking page carries an optional box, unticked until the guest ticks it, that reads "Send me marketing emails and newsletters (optional)", separate from the booking itself, and the table's QR menu offers "Subscribe for promotions". Either way, the guest then receives an email to confirm, and only confirmed subscribers are ever sent a campaign. Guests imported from a spreadsheet are not signed up. The wording of the box is servearound's own, so the promise about what you send and how often belongs in your first email and on your own site.
Each venue's list health shows its confirmed subscribers, the confirmation rate of guests asked in the last ninety days, net growth over thirty days, the unsubscribe rate across recent sends and how many sends went out this week, against the guide that a list sustains about one to three a week. Every campaign carries an unsubscribe link, and campaign analytics show list growth, with the guests who opted in and unsubscribed, for any range. See Campaigns.
Questions operators ask
What is an email opt in?
A guest's active choice to receive marketing emails, separate from the emails that come with a booking.
Should the box be ticked by default?
No. An unticked, optional box that the guest chooses to tick is the basis of a list that works.
What should the words beside the box say?
What guests will receive, how often and who it comes from, and that they can leave at any time.
Does saying how often I write reduce sign ups?
It tends to reassure guests, because their main worry is being flooded. It also sets a promise you must keep.
What is double opt in?
A confirmation email asking the guest to confirm they want to join, which catches typos and proves consent.
Can I email everyone who has ever booked?
Not without their clear agreement. Rules differ by country, and guests who did not choose to join rarely read your emails.
What should I do with an old list?
Ask once whether guests want to stay, keep those who confirm and retire the rest.
Are unsubscribes bad?
A steady trickle is normal. A sudden rise after one email shows that email broke the promise.
The short version
An email opt in guests do not regret starts with an unticked, optional box and honest words beside it: what they will get, how often, who it is from and that they can leave in one click. Saying how often you will write answers the main worry about joining, and sets the standard every email after it is held to.
Confirm the opt in by email, ask at moments when guests are already interested and build the list slowly from guests who have actually been in. Never pre-tick, bundle or buy. Then keep the promise: the rhythm, the content and the sender you described. Measure who confirms and who unsubscribes, and treat a rise in unsubscribes as a sign that an email broke its word.
