Flowium helps ecommerce brands turn BFCM campaigns into more than a short-term sales event. Its BFCM retention audit looks at the customer journey around peak shopping periods, including segmentation, email flows, campaign readiness, and post-purchase opportunities. The approach combines Klaviyo expertise with lifecycle and retention strategy to help brands understand what happens after the holiday order and create stronger paths toward second purchases, re-engagement, and long-term customer value.
