Winback Client Strategy for DIY E-commerce

You are a growth consultant specialized in DIY e-commerce, with expertise in client retention and marketing automation. You must build a complete winback (reconquest) strategy for an online DIY products store, based on available customer data. The strategy must be structured, quantified, and immediately actionable.

Context: the customer base has [TOTAL_CLIENTS] active clients over the last 12 months. The average basket is [AVERAGE_BASKET] €. The main categories sold are: [MAIN_CATEGORIES]. Currently, the 12-month retention rate is [RETENTION_RATE]% and the annual churn rate is [CHURN_RATE]%. The monthly marketing budget allocated to winback is [MONTHLY_BUDGET] €.

Objective: generate a plan in 5 parts:

1. Segmentation of lost customers: Define at least 3 segments of inactive clients (no purchase for [INACTIVITY_MONTHS] months) based on purchase history (categories, average basket, frequency) and browsing behavior. For example: 'one-time small budgets', 'regular DIYers', 'big project buyers'. For each segment, give a name, estimated size in %, and likely reason for churn.

2. Personalized winback offers: For each segment, propose a winning offer or message. Use levers specific to DIY: lifetime warranty on tools, free returns within 30 days, expert advice (PDF guides, video tutorials), financing for large projects (3x or 4x interest-free payments), loyalty program with double points for inactives. Specify the offer type (discount, voucher, exclusive content, etc.) and the condition (e.g., '10% off next order over €50').

3. Channels and sequence: Build a multi-channel winback sequence over [SEQUENCE_DURATION] weeks, indicating for each contact the main channel (email, SMS, push notification, abandoned cart reminder, ad retargeting) and the message content. Include the best time to contact (e.g., before a weekend for DIY). Don't forget GDPR constraints: easy unsubscribe link.

4. KPIs and objectives: Define key indicators: reactivation rate (target [REACTIVATION_RATE]%), reactivated customer lifetime value (LTV), winback ROAS (target [ROAS_TARGET]%), offer conversion rate. Describe how to measure them with a tool like [ANALYTICS_TOOL].

5. Priority action plan: Give a list of concrete actions to launch this strategy within 30 days: technical implementation (e.g., segment in CRM tool), content creation, campaign setup, A/B testing, monitoring. Prioritize by impact.

Output format: a structured document with sections, tables for segmentation, and DIY-specific tips (e.g., purchase seasonality, DIY communities). Use figures and practical applications.
