Activate overview
Activate connects your customer segments to your marketing and advertising platforms, refreshing your audiences daily to deliver personalized campaigns you can measure with confidence.
In this article, you’ll learn what Activate does, how it works, and how to set up your first activation.
How it works
1. Choose your customer segment. Pick a Lexer segment that matches your campaign goals — like lapsed customers, new subscribers, or loyal shoppers.
2. Connect to your marketing platforms. Activate works with leading email, SMS, social, and ad platforms like Braze, Klaviyo, Meta, TikTok, Salesforce, and more.
3. Keep it fresh, daily. Set your activation to automatically refresh each day, adding, removing, or maintaining profiles to keep campaigns up-to-date.
