Your invitations, guest replies and check-in all in one tool
Carton Blanc is French software for invitations, registration and check-in at events by invitation, published by MAKEO SAS. It reminds only the guests who have not replied and keeps the count of who is coming up to date: fewer messages to write by hand, and a room filled to the number you planned.

How it works
An event in five steps
Carton Blanc is online software for invitation-only events, from the guest list to check-in.
Create the event
Title, date, venue, capacity, programme and invitation card. The email for each stage is drafted and dated.
Import your guests
An Excel file or a pasted list of addresses. Duplicates are merged and unsubscribed contacts left out.
Review your emails
You read each email and adjust its wording and send date.
Take registrations
Guests register on the event page and are confirmed at once. When the room is full, they join a waiting list.
Check guests in
On the night, the list opens on your phone. Two days later, each group receives its own message.
Every event has its card
One event, one invitation, one style.
The registration page carries each host's invitation and takes on its colours. Here are 12 templates from the gallery, shown on fictitious events, one or two per occasion.

The mailings
Follow-ups go out on their own
When you create an event, the announcement, the invitation, the follow-up, the reminder the day before and the message afterwards are drafted and dated for you. You read each one once; the follow-up only goes to guests who have not yet replied, and a confirmation goes out with every registration.
Your list belongs to you, can be exported to Excel at any time, and the database is in Paris.

Questions
Frequently asked questions
How long does it take to open a space?
As long as it takes to fill in the form: the space opens at once, and you prepare your events, guests and emails there. You subscribe, or pay for a single event, from within the space. The first mailing is checked by Carton Blanc: if it meets our criteria, it is scheduled without delay; otherwise we reply within one working day.
How many guests per event?
Up to 1,000 guests per event, registrations included, on the subscription and on a single paid event alike. First mailings are capped at 300 recipients; raising the cap up to 1,000 requires approval. Beyond that, write to us.
Can I import my guest list from Excel?
Yes. Carton Blanc imports an Excel file or a simple pasted list of addresses, and merges duplicates.
Where is the data stored, and who owns it?
The database is hosted in Paris, by Supabase (Amazon Web Services infrastructure, eu-west-3 region). Two providers based in the United States also process data to run the service, under standard contractual clauses: Vercel, which serves the application, and Resend, which delivers the emails. The host remains responsible for their guest list; Carton Blanc stores it on their behalf, never sells or passes it on, and the host can export it to Excel at any time.
Can anyone with the link register?
Yes. The registration page of a published event is open to anyone who has its address, until the event starts and within its capacity; beyond that, the person joins the waiting list. Guests who arrive through the link in their email find their name and email address already filled in. The page is not listed by search engines, but it is not password-protected: share the link with that in mind.
How does a guest unsubscribe?
Every email carries an unsubscribe link. Once unsubscribed, a person receives nothing further from that host.
Does Carton Blanc sell tickets?
No. Carton Blanc takes no ticket payments and sells nothing to guests: it handles invitations, registrations and check-in. If the event is paid for, payment happens outside Carton Blanc.
Do invitation cards cost extra?
No. As soon as your account is open, with or without a subscription, you create a card for each event from 503 templates, in English or in French.
In which languages do registration pages work?
In English on cartonblanc.com and in French on cartonblanc.fr. Invitation cards can be created in either language.
Can I pay for a single event, without subscribing?
Yes: €49 incl. VAT (€40.83 excl. VAT), paid once from the event's page in your space. It unlocks that event's emails and its public page only, until 30 days after the date set at the time of payment, follow-up message included. Your other events stay in preparation until they are paid for or covered by a subscription. The first mailing is checked by Carton Blanc in the same way.
Can I withdraw after paying?
Yes, if you are a private individual, within fourteen days of payment. For a single event, you get a full refund as long as the first invitation mailing has not gone out; once it has, the service has been provided and you can no longer withdraw. For a subscription, you pay for the days already used and the rest is refunded. The details are in article 5 bis of the terms of sale.
How do I cancel the subscription?
In one click from your space, with no notice period and no fee. Cancellation takes effect at the end of the period already paid.
Create an account
Your first name, last name and email address are enough to open your space. Everything else waits until it is needed. Preparation is immediate; publication and the first mailing are subject to a check.
Straight away
- Your space opens, and the link to choose your password goes to your address (it is valid for one hour).
- You create your events, import your guests, prepare the emails and make your invitation cards, free of charge.
At your first mailing
- You pay for the event (€49 incl. VAT) or subscribe (€99 incl. VAT a month); your card and billing address are only asked for then.
- Carton Blanc checks your first mailing when you schedule it. If it meets our criteria, it goes out at the time you set; otherwise we reply within one working day.
- The registration page can be published once that first mailing is cleared.
No commitment. Database hosted in Paris.
