Create a Flash Sale Campaign

Campaign flows are the perfect way to send multi-message campaigns to a specific customer segment or your entire subscriber base. With Flow Builder, you can easily visualize and build your flow, add delays between messages, and schedule a start date for sending.

How Flash Sale Campaigns Benefit You


  • Immediately alert your subscribers to sales that have just dropped.
  • Create hype and urgency around these "limited time" promotions with preview and follow-up messages.
  • Structure multi-week flash sales (i.e., weekly promotions) within one campaign flow.

Choose the Segment


Every campaign sends to a subscriber segment. This ensures that campaign messages are only sent to those subscribers who you wish to receive these messages.

Reminder, you will need to create your desired segment before you can select it in the campaign Flow Builder.

  1. Select Messaging in the side menu of your Postscript dashboard, then select Flow Builder.
  2. Select Create Flow in the top-right corner.
  3. Under Campaign, select your desired customer segment from the drop-down.
    • What segment should I choose? Depends! Some shops send flash sales to their entire subscriber base, but you could also send to highly engaged subscribers or those who haven't placed an order recently.
    • Should I choose to exclude a segment? Also depends! A great example of excluding a segment would be if you wanted to send two different sale incentives. You could send your first campaign to a Highly Engaged segment with a lower discount, then exclude that segment from a campaign sent to all subscribers where you use a higher discount. Here, you'd be offering that higher discount to all subscribers except highly engaged subscribers.
  4. Select Create Campaign Flow in the bottom-right corner of the page.

Create Your Campaign


Building out a flash sale campaign flow is easy with Flow Builder's drag and drop functionality. Review how to create a campaign flow, then add the copy, images/GIFs, and delays you desire.

We offer examples below of how you might structure these campaigns. How many messages you include, wait times, and choice of copy will depend on your brand, products, and marketing strategy.
