What should I do if overseas App users lose? Guide to Number Cleaning to Improve User Recall Efficiency

Preface

In the growth process of overseas apps or games, many teams will go through the same stage:

👉 Users are growing rapidly, but retention continues to decline

You may have already tried these:

  • Push notification (Push)
  • Email recall
  • Activity incentives

But the effect is unstable:

  • User open rates are getting lower and lower
  • Active users gradually decrease
  • Recall costs continue to rise

So the question becomes:

👉 Why is it getting harder and harder for users to wake up?

Many teams will attribute the reasons to:

  • The product is not attractive enough
  • Event design is not good enough
  • Decline in user interest

But in actual operations, a lower-level problem is often:

👉User data is not effectively organized, resulting in the inability to maintain continuous contact

User loss is inevitable, but "unrecall" is the problem

Loss is normal

In most apps and games:

  • New user enters
  • short term active
  • subsequently lost

This is a very common life cycle.

The problem is not churn, the problem is:

👉After the loss, can you still reach these users again?

Recall ability determines the upper limit of user value

The value of a user does not only depend on the first use:

  • Is it possible to wake up again?
  • Is it possible to convert multiple times?
  • Can it be retained for a long time?

If there is no recall capability:

👉 User value will be greatly compressed

Why can’t many apps be recalled?

Single reach channel and platform-dependent

Many teams mainly rely on:

  • App Push
  • mail
  • Platform notification

But there are obvious problems with these channels:

  • User may turn off notifications
  • Email open rate is low
  • Platform access is limited

👉 Leading to a gradual decline in the recall effect

There is no unified management of user data

In actual operations, user data is often scattered in:

  • Registration system
  • Behavioral data platform
  • Customer service system

If these data are not organized uniformly, there will be:

  • User information fragmentation
  • Unable to reach unified
  • Difficulty establishing long-term connections

Duplicate and confusing data affect judgment

As the user scale expands:

  • There may be multiple records for the same user
  • Data format is not uniform
  • Unable to accurately identify user

This will bring about a serious problem:

👉 Operational strategies are based on “inaccurate data”

The core role of number cleaning in user recall

In the App growth system, number cleaning is not used to "analyze user behavior", but to:

👉Make user data have basic usability

Establish a unified user contact structure

Mobile phone numbers of users in different countries vary greatly:

  • Country code is different
  • The format is obviously different
  • Users have different filling habits

If not handled uniformly:

👉 It is difficult to establish stable contact channels

Reduce disruption caused by repeat users

In the App scenario, a user may:

  • Register multiple times
  • Use different devices
  • Leave contact information multiple times

If there is no deduplication:

👉 Will affect user scale judgment and reach strategy

Lay the foundation for multi-channel reach

When the data is sorted, you can proceed more stably:

  • Multi-channel reach (such as instant messaging tools)
  • User group management
  • life cycle operations

Otherwise all recalls will become fragmented.

Common recall scenarios for overseas apps

Scenario 1: New users are lost quickly

After registering, many users:

  • Use it once and leave
  • Not forming a habit
  • Silence soon

If there is no data precipitation:

👉 These users will be completely lost

Scenario 2: Active users cannot be reused

During the event, a large number of users will be brought:

  • download
  • register
  • Participate in activities

But after the event:

👉 A large number of users are no longer active

If the data is not organized:

👉 Secondary operation is not possible

Scenario 3: Old users gradually become silent

Among long-term users, there will also be:

  • Decreased use frequency
  • decreased activity
  • eventually lost

These users are actually more likely to be awakened, provided that:

👉 Data can be reused

The positioning of Dingdang Assistant in this link

In the app and game industry, Dingdang Assistant is not:
❌ User Analysis Tools ❌ Behavior Tracking Tools

Instead:

👉User data organization tool

It solves "whether data is available"

Dingdang Assistant can help teams:

  • Unified number format
  • Clean up duplicate data
  • Improve data structure clarity

Let user information change from "dispersed state" to "manageable state".

Why does this step determine the recall effect?

because:

  • Data determines whether it can reach users
  • Contact determines whether we can communicate again
  • Communication determines whether it can wake up users

If the data itself is not available:

👉 All recall strategies will be limited

Transformation from “Growing Users” to “Operating Users”

Many teams focus on:

  • Recruit
  • Place
  • Downloads

But truly sustainable growth comes from:

👉Continuous operation of existing users

The premise of all this is:

👉 User data is clean and manageable

Summarize

In the overseas app and game industry, user loss is inevitable.

But what really widens the gap is:

👉 Who can wake up lost users again?

The key behind this is not a certain marketing strategy, but:

👉Whether the data is organized and used sustainably?

Although number cleaning is basic, it determines:

  • Whether the user can reach
  • Is the operation efficient?
  • Is the recall sustainable?

The value of Dingdang Assistant lies in:

👉 Help you turn "lost user data" into "assets that can be operated again"

FAQ

Q1: Can number cleaning determine whether a user will return?

No, it is only responsible for data collection and does not involve behavioral prediction.

Q2: Why is it becoming more and more difficult to recall users?

Because access channels are limited and data management is not in place.

Q3: Why is App user data easily confused?

There are many sources, large scale, and complex user behaviors.

Q4: Is it suitable for start-up teams?

Suitable, the earlier you establish data sorting capabilities, the more stable your growth will be.
