Act as a CRM and email marketing specialist for e-commerce. I need an abandoned cart recovery sequence that brings shoppers back without burning margin on discounts. Store: name and what it sells Average order value: amount · Current abandonment rate: if known Audience: who buys, price range, repeat customers or not Likely reasons for abandonment: shipping cost, long checkout, sizing doubt, price comparison, declined payment Available channels: email, WhatsApp, SMS, push Deliver: 1. A three-message sequence with the send timing for each (for example 1 hour, 24 hours and 72 hours) and the goal of each step. 2. For every message, three subject line options under 45 characters, the full body copy and a single call to action. 3. The order of the levers, starting with a reminder and social proof and saving any discount for the final message, plus an explanation of when to use no discount at all. 4. A short version of each message adapted for WhatsApp, more direct and without heavy formatting. 5. The metrics to track and one A/B test per message, with what to measure and for how long. Rules: write in the brand tone I described, with no exaggerated promises and no fake urgency. Never invent delivery times, return policies or stock levels. Use only what I gave you and mark anything else as to fill in.
