DUELL POS system
In short: DUELL sends customers with active newsletter consent to Make, and can also automatically publish events as content.
Connect DUELL to Make and save time on customer data
Do you use DUELL as your point-of-sale system? You can connect DUELL with Make, ensuring customers who opt-in to newsletters are automatically added to your system – without manual effort.
What is DUELL?
DUELL is a modular POS system tailored to your industry and configured to meet your needs. It offers an easy-to-use interface for staff while providing managers with full control over sales, tickets, bookings, and inventory management. DUELL features an open API, making it easy to connect with other systems like Make.
How the integration works
Make automatically synchronises contacts who have opted in to newsletters in DUELL (checkbox_marketing_status).

Automatic event content
An optional content integration is also available: it automatically imports events from DUELL via RSS and publishes them as pre-formatted rows or content blocks in Make (the last 50 events). Once you publish an event in DUELL, it appears in Make, ready to be dragged into your newsletter, with the title, image, location, date, and status (e.g., sold out) pre-filled. By adding the "recurring action" add-on, you can automate the entire process.
Why connect DUELL and Make?
No manual lists – opted-in customers are added automatically
Faster content creation – events do not need to be entered twice
Richer data – use date of birth, gender, and address for more precise segmentation
More time for what matters – less time on data management, more time on content and sales
