Postcards Game Mechanics to Drive Engagement

Postcards is less a traditional game than a shareable in-app content mechanic. Instead of competing for points or trying to beat a timer, users choose a branded postcard, customize its message, save the finished image, and send it to someone or publish it on social media.

For businesses, this changes the role of the user: they are no longer only consuming an in-app campaign. They are creating a personalized piece of branded content and potentially distributing it outside the app.

The app team controls the postcard designs. They can feature company branding, products, new collections, campaign characters, seasonal visuals, or partner products. Users then personalize the text, making the final asset relevant enough to send to someone else.

That makes Postcards particularly useful for seasonal engagement, product and partner campaigns, social reach, and brand recognition.

How Does Postcards Game Work?

The interaction is intentionally simple: first, the user enters Postcards from an in-app campaign ( e.g. a Story, banner, in-app message, or a permanent section inside the app). They then see a selection of postcard designs prepared by the app team.

The user:

1. Chooses a postcard.
2. Customizes the text message displayed on it.
3. Generates the final version.
4. Downloads the postcard.
5. Sends it privately or publishes it online.

The visual can be built around almost anything relevant to the campaign:

• a new product;
• a collection;
• a partner brand;
• a brand character;
• seasonal artwork;
• a city or destination;
• an event;
• a company logo or visual identity.

Why Businesses Use Postcards Game

1. It extends an in-app campaign beyond the app

A customer can save a card and send it through a messenger, publish it in a Story, post it on a social network, or share it with a group of friends. If the postcard includes recognizable brand elements or a product, the campaign gains another distribution layer.

The important difference from other promotional campaigns is that this distribution is user-led. Instead of paying for every additional impression, the brand creates something users may voluntarily pass on.

2. Personalization gives branded content a social purpose

People rarely share conventional advertising simply because a company wants additional reach, but a personalized postcard has a different job. It can congratulate someone, make a joke, celebrate a holiday, mark an anniversary, or communicate something between two people. The brand sits inside that interaction instead of being the entire reason for it.

Dodo Pizza's “Love Is” campaign followed this logic. Users created personal cards for people they cared about, while Dodo and “Love Is” branding remained part of the asset. More than 761,000 cards were generated, giving the campaign a distribution mechanism driven by customers themselves.

3. It fits emotional and cultural moments particularly well

Postcards are strongest when people already have a reason to communicate with one another. The strongest concepts start with why the user would want to send something to another person, then determine where the brand fits.

That makes them a natural fit for:

• Valentine's Day;
• Christmas and New Year;
• birthdays;
• Mother's or Father's Day;
• Ramadan and Eid;
• national holidays;
• graduations;
• anniversaries;
• local events;
• major cultural or sporting moments.

For product and marketing teams, its strongest value is social reach, campaign participation, product recognition, and seasonal engagement.
