Deduplication: Eliminate duplicate entries to ensure each contact is managed once.
Standardization: Format all data consistently (e.g., ensuring all phone numbers adhere to Bangladeshi numbering conventions, standardizing job titles, consistently spelling city names like "Sherpur" or "Dhaka").
Verification: Validate email addresses (using email verification services to prevent bounces) and phone numbers. This is critical for deliverability.
Error Correction & Update: Identify and correct typos, incomplete fields, and outdated gambling-data-uae information (e.g., companies that have closed or contacts who have changed roles). Tools like List2Data provide automated solutions for this at scale.
Removal of Invalid/Irrelevant Data: Permanently remove contacts with invalid information or those clearly outside your target geographic or industry scope.
At this phase, your raw, messy list becomes a clean, validated contact base.
Phase 3: Contextual Enrichment (Adding Depth)
Raw list entries typically offer minimal information. Enrichment adds critical context, with potential.
Firmographic Data (for B2B): For businesses, automatically or manually append details like industry classification (e.g., Textile, IT, Fintech in Bangladesh), company size (employees, annual revenue in BDT), website, and precise geographical location (e.g., specific area within Dhaka, or a district in Rajshahi Division).
Demographic Data (for Individuals): For individuals, gather insights such as job title, level of seniority, key responsibilities, and their place within the organizational hierarchy.
