Ran the CSV through our deduper first. Categorisation was granular enough to segment by sub-vertical without regex. One column I'd add next refresh: secondary email.
Picked it up for cold outbound. Address quality is the strongest column in the file. Bought it to handle interior design service lead-gen for the India region. Otherwise no complaints.
CSV opened in Sheets without a single character-encoding glitch. Small thing, but the last database I bought needed two hours of cleanup before I could even filter it.
