# Which email marketing software integrates with CRM systems seamlessly?

<p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">We use Salesforce/HubSpot as our source of truth and need our email data perfectly synced to avoid duplicated contacts. Which <a class="a a--md" elv="true" href="https://www.g2.com/categories/email-marketing">email marketing software</a> integrates with CRM without needing complex Zapier setups? The category leaders seem to be:</p><ul>
<li>

<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/activecampaign/reviews"><strong>ActiveCampaign</strong></a> - Actually includes its own built-in CRM, but also integrates flawlessly with external tools like Salesforce.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/constant-contact/reviews"><strong>Constant Contact</strong></a> - Provides easy-to-configure integrations to ensure your sales team knows exactly which clients received the latest email.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/discussions/Klaviyo"><strong>Klaviyo</strong></a> - Integrates perfectly with ecommerce CRMs and platforms to pull in rich customer purchase histories and custom properties.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/brevo-marketing-platform/reviews"><strong>Brevo</strong></a> - Offers robust API and native CRM connections, keeping your sales and marketing contact records perfectly aligned.</li>
</ul><p class="elv-tracking-normal elv-text-default elv-font-figtree elv-text-base elv-leading-base elv-font-normal" elv="true">Would love to hear from marketing ops folks who have set these up. Which of these tools actually syncs data bidirectionally without creating a mess of duplicates?</p>
