Klaviyo

Klaviyo is an email and SMS marketing platform built around online store data. Beauty brands connect it to their store so it can send messages based on what people browse and buy: welcome series, abandoned cart reminders, replenishment nudges when a product is likely running low, and campaigns for launches. It includes AI features for drafting subject lines and messages and for building segments.

It does the most good when product and order data are clean and your list was collected with proper consent; texting in the US needs express written consent. Have a person check any AI-written claims, especially about ingredients or results, before they go out. Klaviyo has a free plan for small lists.

Paid plans are priced by the number of contacts, so clean old addresses from your list regularly.
