Klaviyo

Drafting a subject line for tomorrow's campaign, or setting up a text that reaches shoppers who left items in their cart, can both happen inside Klaviyo.

Klaviyo is a marketing automation platform that sends personalized email, SMS and mobile push messages based on customer data stored in it.

Its built-in customer data platform unifies that data so you can act on it, and the AI features draft content such as subject lines and surface insights.

Predictive analytics and peer benchmarks show how your results compare with other businesses.

Klaviyo connects with over 300 apps and major e-commerce platforms, which matters when your store data lives somewhere else.

Because data, messaging and automation sit in one product, you may not need a separate tool for each.

As an AI email marketing tool, it suits online stores most.

The AI writing help is mainly meant for short copy like subject lines.
