Detailed Review
Bouncer is run by Bouncer Sp. z o.o. (LTD), a Polish limited company at ul. Cypriana Kamila Norwida 24/1, 50-374 Wroclaw. Its privacy policy names the company as data controller for people in the European Economic Area. The terms of use are governed by the laws of Poland.
The privacy policy states that its servers are in Frankfurt, Germany, and that data may be transferred to other countries together with third parties it shares data with. That is a more specific hosting statement than most tools in this list give.
Products around verification
The product menu lists email verification, an API, Bouncer Shield for catching invalid or fraudulent addresses at entry, AutoClean for CRMs, a toxicity check, data enrichment, a deliverability kit for inbox placement and blocklists, and engagement insights. It also lists an MCP server for connecting LLM tools. We did not test any of these.
Dollar pricing and no expiry
The pricing page shows dollars. Credits never expire and no credit card is needed to start. The minimum purchase is 1,000 credits at USD 8, falling to USD 2,000 for 1,000,000. A subscription tab exists next to pay as you go.
Compared with ZeroBounce
Both sell verification plus deliverability extras. Bouncer places inbox placement and blocklist checks in a Deliverability Kit. Bouncer also advertises a guarantee on accuracy, but its terms were not read for the exact wording, so compare that clause before you decide.
Limitations to Consider
Prices are shown in USD, not euros. The terms of use carry a last-update date of 24.08.2018 and the privacy policy 01.05.2019, so the legal text is old. We did not read the wording of the Bouncer Guarantee, and the privacy policy allows transfers outside Germany to third parties it shares data with.
Who Should Use Bouncer
Teams that verify lists and sign-up forms and want a Polish contracting entity with stated Frankfurt servers. For euro prices see EmailListVerify.
