BounceBlock for agencies
Clean any client list, flat-priced, in minutes. Verify email and phone and remove duplicates across every client account without per-verification credit math eating your margin.
The problem for agencies
How BounceBlock helps
Upload any client's CSV, auto-detect the columns, and hand back a verified, deduplicated file — email and phone both checked. Flat pricing means you can clean lists for every client as often as needed without watching a credit balance.
Protect every client's domain
Verifying before each send keeps your clients' bounce rates low and their sender reputations intact — the difference between a campaign that lands and one that gets filtered.
