If you want to organize a giveaway with a closed list of participants quickly, securely, and with complete transparency, Easypromos is the platform for you. With our internationally certified random draw engine, selecting winners has never been easier or more reliable. In this article, we’ll look into real examples from well-known brands and companies that use our system to select winners from a closed participant list, with full guarantees of fairness and compliance.

Many clients contact us to run giveaways and choose a winner from a list. They need a transparent and reliable way to quickly select winners. The Pick-a-Winner app solves this by randomly choosing winners from an uploaded list, such as monthly customers, app users, loyalty club members, and workshop attendees. Easypromos clearly displays the winners, always ensuring user security and privacy, and complying with current data protection regulations.

 

Choose a Winner From a List of Club Members

The supermarket chain Alcampo regularly organizes giveaways for its Alcampo Club members. These promotions help boost loyalty and encourage repeat purchases. Often, the giveaways target children and families, promoting club membership as a way to access raffles, workshops, and in-store activities. In this example, all members who had purchased Superman or DC Comics products could complete a registration form to enter the draw.

Alcampo needed to randomly select 6 winners from the registered participants. One winner received a trip for two to Los Angeles to visit Warner Bros Studios, while five others won merchandise packs valued at €120 each. Due to the high value of the prizes, especially the trip (worth €5,000), and the fact that participants were loyal club members, the giveaway had to be completely transparent and reliable. Alcampo used Easypromos for every step: uploading the participant list, setting the winners and alternates, and conducting the random draw, while protecting chosen data fields for privacy.

 

 

Giveaway to Generate Leads with Tools like HubSpot

The school supply brand Milan organized a giveaway to celebrate the start of summer and promote its products during the holiday season, when children have more free time. The brand gave away a “Vacation Survival Kit”, a set of four products promoted across social media and online channels. The goal was to capture leads interested in the brand’s products and expand their database. Milan used a registration landing page created in HubSpot, which optimized the sign-up process and automatically stored participants’ data for future email marketing campaigns.

Choose a Winner From a List of Customers Who Complete a Survey

The beauty and cosmetics brand Primor offers a monthly subscription product called Primor Box, which includes a surprise selection of 6 to 8 items, such as makeup, perfume, skincare, personal care, accessories, or nutrition items. This dynamic provides a positive experience, giving users a perception of value and savings.

Subscribers receive their box each month, and one of the key features of the service is a monthly survey, where customers share feedback about the products they received. To encourage more responses, Primor runs a <b>giveaway among customers who complete the survey</b>. The brand then uploads the list of respondents to Easypromos to randomly select winners. They can choose which data fields to display, such as customer ID, survey number, name, or email, allowing them to increase response rates while protecting customer privacy.

Giveaway to Capture Reader Data through the Website

In the media industry, generating website visits is essential for maintaining advertising revenue. But it’s equally important to turn those anonymous visits into identified contacts for ongoing engagement. To achieve this, Diario de Sevilla runs giveaways promoted on social media but hosted on their website. The web page includes the key giveaway details and a registration form for participation. In this example, Diario de Sevilla raffled two tickets to the show “Disfrutona” by Eva Soriano. After the participation period ended, the participant list was uploaded to Easypromos to randomly select the winner.

Giveaway to Boost the Purchase of a Specific Product

Choosing a winner from a list offers a transparent solution when you already have a pool of participants from a specific promotion, but still need a tool to select random winners. That was the case for Bon Preu – Esclat supermarkets, which ran a promotion to encourage the purchase of Froya salmon. The promotion was advertised in stores through flyers and posters, as well as on social media. The supermarket chain also partnered with an influencer who shared a recipe video featuring the product.

All customers who purchased the product during the promotion period and identified themselves with their loyalty card were automatically entered into the giveaway. The supermarket then easily compiled a participant list and used Easypromos to randomly select 1 winner and 10 alternates in case of any issues or unclaimed prizes. Because the goal was to promote product sales, no additional user data was required — participation was automatic upon purchase.

The Easypromos’ random draw engine is certified and approved under the international GLI-19 v3.0 standard, which defines the strictest technical and security guidelines for online gaming and random selection processes.

 

 

Choose a Winner From a List of Users Who Register Through an App

Running giveaways and promotions through a brand’s mobile app is a common strategy to increase app engagement and downloads. Beyond encouraging installations, brands also need to offer new experiences and exclusive events to keep users active. In this example, the Lagoh shopping and leisure center in Seville promotes the download of its Club de los Disfrutones app by organizing exclusive in-app giveaways. Although these giveaways are promoted through the website and social media, participation happens directly within the app.

In one campaign, users could sign up for a VIP pass giveaway to meet the children’s cartoon character Pocoyó. Since users were already identified in the app, registration was fast — no forms required. Once the participation period ended, the marketing team downloaded the list of registered users and uploaded it to Easypromos to randomly select 3 winners and 3 alternates, as stated in the terms and conditions.

As we’ve seen, with Easypromos, any brand can run a giveaway from a closed participant list — quickly, reliably, and in full compliance with data protection laws.

Whether your goal is to reward loyal customers or capture new leads, your giveaways will not only be fair but will also deliver measurable value to your business.
