What is Retention?
Keeping existing customers buying from you over time. Retention marketing (email flows, loyalty programs, re-engagement ads) is 5-7x cheaper than acquisition marketing.
Retention economics
Acquiring a new customer costs 5-7x more than retaining an existing one. A 5% increase in retention rate increases profits by 25-95% (Harvard Business Review). For subscription brands, retention is the primary driver of LTV: doubling average retention from 6 months to 12 months doubles LTV without changing price or acquisition cost. Retention marketing is not glamorous, but it is the highest-ROI marketing you can do.
Retention marketing channels
Email (highest ROI, $36 return per $1 spent): post-purchase sequences, win-back flows, VIP programs, replenishment reminders. SMS (high engagement, 98% open rate): flash offers, shipping updates, loyalty rewards. Retargeting ads (paid but targeted): new product launches to existing customers, cross-sell campaigns, seasonal reminders. Loyalty programs: points, tiers, early access. Use all four channels in a coordinated retention strategy.
Creative for retention
Retention creative differs from acquisition creative. It assumes familiarity and focuses on deepening the relationship: "how to get more from your [product]" content, exclusive early access to new products, loyalty rewards and VIP status, and personalized recommendations based on purchase history. AI tools generate retention email and ad creative tailored to each customer segment, maintaining your brand voice while varying the message by engagement level.
