Webbula is the leader in email hygiene, email verification, and data enhancement solutions. Clean, protect, and grow your email database. Webbula has a dedicated self-service opt-out form at webbula.com/opt-out-request/, or you can call 800-533-5853 to be suppressed from their marketing databases. Their own CCPA statistics report a median of about 1 day to process opt-out and deletion requests, though they may ask for extra information to confirm who you are; separate pages exist for data access requests (webbula.com/ca-eu-data-request/). Since Webbula continuously ingests data from other commercial and public sources, it's worth re-checking your suppression periodically.
