Third-Party Data & Your ESP

Strict compliance rules and inaccurate data can lead to serious deliverability issues, making it risky to send third-party data directly to your ESP. That’s why we built the Customers.ai ESP.

Think of Customers.ai as your pre-ESP bouncer. We’ll filter out the tire-kickers, warm up high-intent contacts, and only send your ESP the ones worth hosting. 

Want to ensure your third-party data is 100% compliant? Let us do the emailing for you. Third-party contacts will only be added to your ESP when they purchase or give you their information, making them first-party contacts, and ensuring 100% compliance.

Identity is core to Blotout. We tested multiple data providers, and Customers.AI was the clear leader—superior accuracy, higher match rates, and real value. Most others performed extremely poorly in our testing and provided no observable incremental value.

We work alongside your ESP, cutting costs and protecting your brand

Guard your sender reputation and ensure your emails reach the inbox, not the spam folder.

We support existing ESPs and recommend using Customers.ai alongside of, or in place of, your ESP for website visitor identification data. 

Website Visitor ID tools generate +10x more emails but also +10x your Klaviyo bill. Save money by keeping your third-party data directly in Customers.ai

Keep your previously anonymous visitor email automations separate. Push contacts to your other ESP when they take a qualifying action or only when they become a paying customer.

Utilize the powerful customer journey and consumer data to segment and power your automations.

Design beautiful, high-impact emails effortlessly that captivate and convert your audience.

Reach and convert website visitors with personalized messaging at scale.
