How to Run a Flash Sale

13 July 2026·1 min read

Quick answer: Run a flash sale by making a genuinely good, time-limited offer (usually 24–72 hours), building brief anticipation, promoting it hard across email and social, creating real urgency, and reminding people before it ends. Flash sales work because scarcity and urgency drive fast action — but keep them occasional so they stay special and don't train customers to only buy on sale. 🌴

A flash sale drives a fast burst of sales — here's how to run one that works. 💖

How to run a flash sale

Genuinely good offer — worth acting on
Time-limited — 24–72 hours
Promote hard — email and social
Real urgency — and reminders
Keep it occasional — so it stays special

💡 Urgency drives action — use it sparingly. A tight deadline is what makes a flash sale convert. But run them too often and you train people to wait for a discount — keep flash sales occasional so they stay exciting and protect your margins.
