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.
Prepare the mailings
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 eight imaginary events: two galas, a birthday, a classic card, a tasting, a private view, a business meeting and a talk.

The product
From registration to check-in
On the night, the guest list on your phone.
The mailings
The email calendar
When you create an event, every email is drafted and dated in relation to it, on the same day of the week. The D−14 reminder goes only to guests who have not yet registered.
Six weeks before
The save the date, with your invitation and a link to reserve a place.
Four weeks before
The invitation: programme, speakers, venue.
Two weeks before
A gentle reminder, sent only to guests who have not yet replied.
The day before
The reminder to those attending, with the address and a calendar link.
The evening
Check-in on your phone.
Two days after
The follow-up, with one message for those who came and another for those who could not.
Each registration is confirmed at once; when the room is full, the guest joins the waiting list and is told so.
Guests and the partners who invite them
Import your lists from Excel or simply paste in addresses; duplicates are merged. A partner inviting their own members gets a dedicated link, and every registration through it stays credited to them. Anyone who unsubscribes receives nothing further from you.
Your data
Your guest list belongs to you: you are responsible for it, and Carton Blanc hosts it on your behalf, within the European Union. Each host has their own space, kept apart from the others by the database itself.

Carton Blanc and free tools
- A guest list, not a box office
- Ticketing platforms sell places to the public. Carton Blanc handles guests chosen by the host: invitations, reminders, registrations and check-in. It takes no payments.
- Clear funding
- A free tool is funded some other way, for example by a fee on tickets, advertising or a paid plan for advanced features. Carton Blanc is funded by what the host pays, subscription or single event, and by nothing else.
- A draft for every stage
- When the event is created, the email for each stage is written and dated; the host reworks them at their own pace before they go.
- Data in Europe
- The guest list and registrations are stored in the European Union, in Paris, and can be exported to Excel at any time.
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.
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?
In the European Union, in Paris. 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.
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 around fifty styles, 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.
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.
