Strategy 1: Device and Browser Fingerprinting

What is device and browser fingerprinting

Device and browser fingerprinting is a technique employed to identify and track individual devices accessing online resources by collecting unique information about their specific hardware and software configurations. This information can be used to differentiate between legitimate and illegitimate users, thus aiding in the prevention of SMS pumping in marketing campaigns.

How does it work

• Collecting hardware and software details: Fingerprinting involves gathering data points such as device model, operating system version, browser type, user-agent string, IP address, screen resolution, and installed plugins. These data points form a distinct profile for each device that can be used for identification and tracking purposes.

Strategy 2: Phone Verification

What is phone verification

Phone verification is a security measure that helps authenticate the legitimacy of a user's phone number used in SMS-based communication. It adds an extra layer of validation and protection against SMS pumping by ensuring registered phone numbers are connected to real, legitimate users.

How does it work

• User's phone number verification: During the registration or opt-in process for SMS-based services, users must provide their phone numbers. The phone verification process sends a unique, temporary code to the provided phone number, either through a text message (SMS) or a phone call. Users then enter the code on the platform to prove they own and control the phone number associated with their account.
• Limiting access to verified phone numbers: Only users who successfully complete the phone verification process may proceed to participate in SMS-based campaigns or services. This validation step deters fraudsters from using fake numbers and reduces the number of illegitimate users in the system.

Pros & cons

• Improved campaign security: Phone verification significantly decreases the likelihood of SMS pumping by ensuring that the phone numbers used in campaigns are tied to actual users and not fraudulent entities.

  
  

• Hindrance to legitimate user engagement: Phone verification might be seen as inconvenient to some users. It adds an extra step in the registration process, which may lead to a drop-off in user engagement if not properly executed.

Implementation tactics

• Selecting phone verification methods (SMS, calls): Determine the most suitable phone verification method for your audience and business. SMS-based verification usually offers a seamless user experience and can be more cost-effective. However, phone call verification can provide an additional layer of security, particularly for high-risk scenarios.

  
  

• Implementing third-party phone verification services: Several third-party services specialize in providing phone verification solutions. Utilize these services to integrate phone verification into your sales funnels, registration processes, and SMS marketing campaigns. When selecting a verification service, make sure to consider factors such as the provider's security measures, user experience, and compliance with industry regulations.

  
  

• Periodically re-validating user phone numbers: Users may change or deactivate their phone numbers over time. Setting up a system to periodically re-validate phone numbers will ensure that your database remains up-to-date and accurate. By doing so, you'll prevent inadvertently sending SMS messages to inactive or unresponsive users and minimize the risk of SMS pumping fraud.

  
  

Strategy 3: Disposable / Temporary Email Detection

What is disposable/temporary email detection

Disposable or temporary email detection is a technique to identify and filter out users who have signed up for SMS marketing campaigns using temporary email addresses. These addresses are often used by bad actors to engage in SMS pumping fraud by creating multiple temporary accounts. By detecting and blocking such users from participating in the marketing campaign, businesses can enhance the integrity and efficiency of their SMS-based advertising efforts.

How does it work

Temporary email detection involves identifying whether the email address associated with an SMS marketing campaign participant is linked to a temporary, disposable, or fraudulent email provider. These providers enable users to create temporary email addresses for a short period and can be used to bypass SMS verification processes.

When a suspicious email address is detected, businesses can block or flag the account to prevent the user from receiving promotional messages and being counted towards campaign performance metrics.

Pros & cons

• Pro: Reduces the chances of SMS pumping fraud, as bad actors using temporary email addresses will be blocked or flagged from participating in the campaign
• Pro: Saves resources and costs associated with sending SMS messages to fake users
• Con: False positives may occur, where legitimate users with less-common email providers are incorrectly flagged as suspicious
• Con: Businesses must regularly update their list of temporary and disposable email providers to maintain the effectiveness of this strategy

Implementation tactics

1. Deploy disposable email detection tools: Many software tools and APIs are available for detecting temporary and disposable email addresses. By incorporating these tools into the account creation and verification process, businesses can automatically screen and flag suspicious email addresses.
2. Integrate third-party email validation services: Several email validation services can identify disposable and temporary email addresses as part of their overall email verification process. By integrating these services into the existing account verification system, businesses can strengthen their protection against SMS pumping fraud.
3. Setting up alert systems for flagged accounts: Implement a monitoring system that sends alerts or notifications when a suspicious email address is detected. This allows for prompt investigation and action to be taken against potential SMS pumping fraud. Additionally, it helps digital marketing teams to continuously monitor and adjust the efficacy of their SMS marketing campaigns based on real user data.

Through the effective deployment of disposable email detection tools and methodologies, businesses can enhance the security and relevance of their SMS marketing campaigns by preventing and mitigating the impact of SMS pumping fraud on their campaign performance metrics.

Strategy 4: VOIP Phone Detection

What is VOIP phone detection

VOIP (Voice over Internet Protocol) phone detection is a cybersecurity strategy used to identify and block virtual phone numbers, which are often utilized by fraudsters to carry out SMS pumping schemes. By leveraging VOIP detection mechanisms, businesses can enhance the security of their SMS marketing campaigns and ensure only legitimate phone numbers are used by users.

How does it work

VOIP phone detection works by analyzing the phone numbers provided by users during registration, opt-in, or engagement with SMS-based marketing campaigns. It identifies phone numbers that are associated with VOIP providers instead of traditional mobile carriers. When a virtual phone number is detected, businesses can take appropriate actions, such as blocking or flagging these numbers, preventing potential SMS pumping fraud and conserving resources intended for genuine user engagement.
