Unlocking New Efficiency in SMS Mass Marketing: In-depth Analysis of Core Number Screening Logic to Achieve Dual Growth in Delivery and Conversion Rates

In today's digital marketing landscape, precision SMS marketing is gaining increasing attention from businesses as an effective means to directly reach users. However, many enterprises often face challenges such as low delivery rates and unsatisfactory conversion outcomes when conducting precision SMS marketing campaigns. The root cause is frequently not the content of the messages themselves, but rather the lack of a scientific and effective logic for screening core phone numbers. This article provides an in-depth analysis of how to build an intelligent number screening system through efficient screening tools—such as the ITG Global Screening System—to fundamentally enhance the delivery and conversion rates of SMS marketing, achieving dual growth.

1. The Dilemma of SMS Marketing and the Key to Breakthrough

Traditional SMS mass marketing often adopts a "wide-net" approach, sending the same content to a vast number of phone numbers. While this method covers a broad reach, it suffers from three core pain points:

1. Low Delivery Rate: A large number of invalid numbers, disconnected or inactive numbers, and silent users result in messages failing to reach their intended recipients.

2. Low Conversion Rate: Non-target users receiving messages not only fail to convert but may also generate negative feedback.

3. High Cost Waste: Ineffective sends directly waste marketing budgets, making it difficult to improve ROI.

The key to overcoming these challenges lies in shifting the focus from "quantity" to "quality," and the core tool to achieve this shift is a professional number screening system. The ITG Global Screening Tool is designed precisely to address this issue. Through multi-dimensional data analysis and intelligent algorithms, it helps businesses identify the most valuable core user numbers.

2. In-depth Analysis of the Core Logic of the ITG Global Screening Tool

2.1. Basic Data Cleansing: Removing Invalid Numbers

The ITG system first performs basic data cleansing by integrating real-time operator data to automatically identify and filter out the following types of invalid numbers:

• Disconnected, inactive, or non-existent numbers

• "Zombie numbers" that have been unused for extended periods

• Numbers recently deactivated or canceled

• High-risk numbers and numbers with frequent complaint records

This basic screening can immediately improve the delivery rate by 10%–30%, preventing resources from being wasted on numbers that cannot receive messages.

2.2. User Activity Stratification: Focusing on High-Value Groups

Merely removing invalid numbers is insufficient. The ITG system further analyzes user communication behavior data to stratify the number database into different activity levels:

• Highly Active Users: Frequent recent communication records, high receptiveness to SMS

• Moderately Active Users: Regular but not frequent communication behavior

• Low-Activity Users: Sparse communication records, possibly secondary or infrequently used numbers

Precision SMS marketing strategies should adopt differentiated content and sending approaches based on these activity levels. Highly active users can receive richer marketing messages, while low-activity users require more cautious outreach strategies.

2.3. Interest and Preference Profiling: Achieving Precise Content Matching

The ITG system analyzes multi-dimensional data such as users' historical consumption behavior, app usage habits, and search keywords to build interest and preference profiles for each number. For example:

• Users frequently searching for "fitness courses" can be categorized into the "healthy lifestyle" interest group

• Users regularly purchasing maternal and infant products can be tagged as "parenting families"

• Users frequently using travel apps can be classified as "travel enthusiasts"

Implementing precision SMS marketing based on interest preferences can increase conversion rates by 2–3 times. The intelligent categorization feature of the ITG system simplifies this complex process, making it efficient and effective.

2.4. Spatiotemporal Context Adaptation: Capturing Optimal Outreach Timing

Users' receptiveness to SMS varies significantly depending on the time and location. The ITG system analyzes users' historical behavior patterns to identify the best sending times:

• Commuters: High open rates during 7–8 AM and 6–7 PM

• Nightlife enthusiasts: Better reach during 9–11 PM

• Weekend-focused families: Higher response rates on Saturday and Sunday mornings

Additionally, screening logic based on geographical location can enhance marketing effectiveness. For example, sending promotional messages about nearby stores to users located near shopping malls can bridge online and offline interactions.

3. Practical Strategies for Achieving Dual Growth in Delivery and Conversion

3.1. Phased Testing and Optimization Cycles

Implementing precision SMS marketing should not be a one-time, static activity but a dynamic optimization process. It is recommended to adopt a cycle of "small-scale testing → data analysis → strategy adjustment → expanded promotion":

1. Use the ITG system to select a representative test sample from the full number database.

2. Send different versions of content and collect data on delivery, open, and conversion rates.

3. Analyze performance across dimensions to identify the best screening combinations and content strategies.

4. Optimize screening logic based on test results and expand its application.

3.2. Multi-Dimensional Combined Screening Models

Single-dimension screening often yields limited results. The ITG system supports the creation of multi-dimensional combined screening models, such as:

"High activity + interest match + recent relevant consumption behavior + optimal timing users"

While this refined screening may reduce coverage volume, it significantly improves conversion efficiency, resulting in a higher ROI.

3.3. Dynamic Updates and Real-Time Adjustments

User status and preferences are dynamic; a highly active user yesterday may have changed their number today. The strength of the ITG system lies in its ability to update data in real time and dynamically adjust screening logic:

• Regularly update number status (recommended at least once a month for a comprehensive update)

• Track changes in user behavior in real time and dynamically adjust interest tags

• Optimize screening parameter weights based on feedback data from marketing campaigns

3.4. Compliance Screening and Risk Prevention

While pursuing marketing effectiveness, compliance risks must be considered. The ITG system includes a built-in compliance screening module that automatically identifies:

• User numbers registered on "Do Not Disturb" lists for commercial messages

• Sensitive users with high historical complaint rates

• Special group numbers restricted by laws and regulations

Avoiding sending marketing messages to these numbers not only reduces legal risks but also minimizes negative user feedback, safeguarding brand reputation.

4. Case Study: The Efficiency Leap Brought by the ITG Screening Tool

An e-commerce platform, when using traditional mass messaging methods, achieved an average SMS delivery rate of 78% and a conversion rate of only 0.3%. After implementing the ITG Global Screening System, the platform underwent a three-phase optimization:

• Phase 1: Basic cleansing removed 30% of invalid numbers, increasing the delivery rate to 92%.

• Phase 2: Activity stratification optimized sending times for highly active users, boosting open rates by 40%.

• Phase 3: Interest profile matching enabled personalized content recommendations, raising the conversion rate to 1.2%.

Ultimately, with a 25% reduction in total sends, the platform achieved over 300% higher conversion revenue through precision SMS marketing, truly realizing the marketing effect of "less is more."

5. Future Outlook: Trends in Intelligent Screening Development

With advancements in artificial intelligence technology, number screening logic is evolving toward greater intelligence:

1. Predictive Screening: Using machine learning algorithms to predict future user needs and initiate marketing outreach proactively.

2. Emotional Intelligence Adaptation: Analyzing user emotional states to select the most appropriate communication timing and tone.

3. Cross-Channel Integration: Integrating SMS screening logic with email, app push notifications, and other channels for omnichannel unified marketing.

4. Automated Optimization Systems: Systems that adjust screening strategies based on performance data without manual intervention.
