The problem for agencies

Every client list arrives messy and in a different format.
Credit-metered tools get expensive across many accounts.
Bad data risks your clients' sender reputations — and your retainer.

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.
