What ActiveCampaign is

ActiveCampaign is a powerhouse platform that combines advanced email marketing, marketing automation, and a sales CRM. It is designed for businesses that want to implement sophisticated, data-driven customer journeys. With its 'CXA' (Customer Experience Automation) approach, it uses machine learning to predict the best time to send emails and which content will resonate most with individual subscribers. It is the gold standard for anyone who needs the deepest possible automation capabilities and a unified sales/marketing view.

What Klaviyo is

Klaviyo is the smartest marketing automation platform for e-commerce. It uses store data to analyze 'who bought what and when.' This lets you build incredibly detailed automations like 'send a discount to customers who haven't bought in 30 days but have spent over $500.' Known as the 'brain of e-commerce,' it is the top choice for brands looking to turn data into sales.
