Send SMS Flash Sale Alerts
Notify customers instantly about flash sales via SMS for high urgency
Klaviyo SMS automation that sends time-limited sale alerts (24-hour flash sales, flash deals) via SMS to opted-in customers, driving immediate traffic and high conversion.
Email has a 1-2 hour open window; SMS has a 3-minute response window. This automation triggers SMS campaigns for flash sales and limited-time promotions, reaching customers instantly when they're most likely to act. When Nora detects a new flash sale (24-hour 30% discount, limited inventory, etc.), it sends SMS to segmented audiences: VIPs get exclusive early notice (30 minutes before public), all customers get the announcement, repeat buyers get an exclusive code. SMS includes: what's on sale, discount percent, how many hours left, and direct link. The automation throttles SMS volume — never more than 2-3 per week per customer (SMS fatigue kills opt-in rates fast). SMS reaches a phone in seconds, which is the only reason a time-boxed sale works at all. Klaviyo tracks clicks and attributed orders per send, so each flash sale is measured against the last one. Even at $50 average, that's $40,000 from a single SMS blast. A sale can go out within minutes of the decision to run it, which is what makes it a flash sale.
Runs triggered on flash sale event (real-time) using Klaviyo, run by your Ecommerce Manager.
