# ZoomInfo's GTM Workspace vs Apollo.io vs Cognism: which sales intelligence platform actually gives better data accuracy for teams selling into Europe?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">ZoomInfo's GTM Workspace vs Apollo.io vs Cognism: which<a class="a a--md" elv="true" href="https://www.g2.com/categories/sales-intelligence"> </a><a class="a a--md" elv="true" href="https://www.g2.com/categories/sales-intelligence">sales intelligence</a> platform actually gives better data accuracy for teams selling into Europe? I've been reviewing this specifically because general accuracy comparisons rarely break out European performance, and after going through G2 reviews filtered to users based in Europe, the gap between these three is more pronounced for EU prospecting than the headline numbers suggest.</p><ul>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/cognism/reviews"><strong>Cognism</strong></a><strong>:</strong> European users rate contact accuracy highest, with human-verified Diamond Data described as reducing manual research from days to hours specifically for direct-dial accuracy in the UK and Western Europe. Italy and some Southern European markets are flagged as thinner.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/apollo-io/reviews"><strong>Apollo.io</strong></a><strong>:</strong> Praised for granular filtering and reliable contact data that consistently closes deals, though higher bounce rates in some markets outside the UK come up in European user reviews.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/gtm-workspace-powered-by-zoominfo/reviews"><strong>GTM Workspace by ZoomInfo</strong></a><strong>:</strong> Strong for US contacts, with European users praising the filtering and speed but noting a verification step is still recommended before outreach specifically into European markets.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">For teams primarily selling into the UK and Western Europe, which of these has actually moved the needle on connect rates? Has anyone run a direct bounce rate comparison across two of them on the same target list?</p>

The thing is, &quot;Europe&quot; isn&#39;t one data market. It&#39;s a dozen, and a tool that&#39;s excellent on UK or DACH direct dials can fall off a cliff two borders over. So a single accuracy figure for the whole continent averages away the only thing you care about: how it does in your specific countries. So the honest comparison is per-country, not per-platform. Anyone who&#39;s run the same target list through two of these would add more than another feature rundown.
