Regular Cleaning: Periodically use a reputable email verification service to identify and remove invalid, inactive, or risky email addresses.
SMS Number Validation: Use carrier lookup services to confirm phone numbers are active and can receive SMS.
Deduplication: Regularly identify and merge duplicate records to maintain a single, accurate profile for each contact.
Unsubscribe/Opt-Out Management: Process unsubscribes immediately and remove those contacts from your active marketing lists to comply with regulations and respect user preferences.
Re-engagement Campaigns: Attempt to re-engage inactive subscribers before removing them entirely. Neglecting data hygiene leads to higher bounce rates, lower deliverability, damaged sender reputation, and wasted marketing spend. A clean, healthy database is a performing database, crucial for consistent marketing success.
