Visit website What is it?
Klaviyo is the email and text message platform most Shopify stores run on. It plugs into your store, watches what every customer browses and buys, and sends the right message at the right moment: welcome series, abandoned carts, back-in-stock, win-backs.
Its AI drafts subject lines and email copy, builds customer segments from a plain-English description, predicts who is about to churn, and suggests the best time to send. It also has an official connection for Claude, so you can ask questions about your campaigns and customers in chat.
Pricing climbs quickly as your list grows, and it's built for product businesses. Service companies and B2B teams often find HubSpot or a simpler newsletter tool a better fit.
Who it's for
Online stores that want their email and SMS to run on real customer behaviour.
Best for
- Abandoned cart recovery
- Segments from plain English
- Post-purchase flows
- SMS campaigns
- Predicting customer value
Why it made the list
The deepest store integration of any email tool, and the one with the most useful AI for retention.
