# Why Is the Delivery of Cards Delayed?

> Card delivery in MoEngage depends on the user opening the app. Learn why cards may be delayed and how the SDK fetches campaign data on app launch.

## Problem

The cards are not delivered right after the campaign is published.

## Explanation

* When you publish a Card campaign and the user opens the app, the MoEngage SDK sends the Card campaign data to the user's device.
* The SDK checks the eligibility of all Card campaigns for that device and posts the eligible ones.
* If the user performs the *App/Site open* action later than the campaign launch, the card may not be received in time.
* After the user performs the *App/Site open* action, the card is delivered within 2-3 minutes.

In the following example, the user received the card after a delay because the *App/Site open* action wasn't performed earlier. The activity info shows that the card was delivered within 2-3 minutes after the *App/Site open* action was completed.
