Before extracting insights, it’s crucial to prepare your phone number list thoroughly. The quality and accuracy of your data directly impact the usefulness of your analysis.

Standardize Formats: Convert all numbers to a single international phone number list format, such as E.164, for easier analysis. This ensures consistency and reuces errors in processing. For instance, a number like . A 123. 456-7890 should be converte to +11234567890.
Filter Inactive Numbers: Identify and remove numbers that have bounce or opte out. Keeping your list clean helps maintain engagement rates. Regularly check for opt-out requests to ensure compliance with regulations.
2. Organize Your Data with Relevant Attributes

Country and Region: Helps in geographic segmentation. For example, a business can tailor its marketing strategies base on regional preferences.
