Question: I'm looking for a solution that enables personalized marketing campaigns across multiple channels using first-party data.

Iterable is an all-purpose cross-channel marketing system that uses real-time data to personalize customer interactions. It offers personalized messages, synchronized channels and dynamic campaigns across the web, email, SMS, in-app and other channels. The system's AI features include customizable predictive goals, generative AI and AI-boosted optimization, so it's a good option for companies that want to improve customer engagement and conversions.

Another contender is Bluecore, which is designed to maximize revenue by using customer data for targeted marketing. It uses predictive AI models trained on real-time behavior to offer 1:1 recommendations and promotions, and to optimize campaigns across email, site, SMS and paid media. Bluecore also has a customer-centric approach with high retention rates and a Customer Movement Assessment that helps retailers identify the highest growth opportunities.

For a more AI-heavy approach, check out Braze, a customer engagement platform that uses Sage AI to oversee real-time interactions between consumers and brands across many channels. Braze offers data activation, journey orchestration and cross-channel messaging for a very personalized experience. It's geared for retail, media and financial services, helping companies optimize onboarding, engagement and customer retention.

Last, Marketing Cloud Engagement from Salesforce is a unified customer engagement system with personalized marketing and automated journeys.
