CRM Recency Segmentation Drives Holiday Repeat Purchases
This article provides a guide for marketers on using CRM segmentation, specifically a recency ladder, to drive holiday repeat purchases. It categorizes customers into four segments: recent, active, drifting, and dormant. The strategy involves always-on campaigns for recent customers, while lapsed customers receive targeted email and paid media campaigns during the holiday season. The article emphasizes the importance of deliverability for dormant groups and suggests personalized messaging. It references Deloitte's holiday sales forecast and highlights the effectiveness of Meta's Conversions API for targeting high-value users.
- Deloitte forecasts holiday sales growth of 4.0% to 4.8% in 2026, with online sales rising 7.5% to 8.4%.

AI Disrupts Legal Billable Hour
Artificial intelligence is reshaping the legal profession, with nearly 90% of legal professionals in the U.K. and Ireland now using AI, according to Clio's Legal Insights Report 2026. Among firms using AI, about 80% report handling more work without extra resources, and over 70% say it cut costs by automating administrative tasks. This is challenging the traditional billable hour model, as tasks that once took hours now take seconds. Major firms like A&O Shearman and Slaughter and May are deploying AI tools like Harvey to speed up document review and regulatory analysis. The report indicates about one in five firms with wide AI adoption struggle to meet billable-hour targets, and Deloitte predicts the share of work billed by the hour will drop from 72% to 44% in two to three years. While routine work is most affected, complex work still requires human judgment. Firms are also rethinking junior lawyer training, with a focus on skills like connecting diverse areas to solve complex problems.
