Email is the highest-ROI channel in eCommerce -- but only when you go beyond one-time campaign blasts and build automated sequences that run in the background and generate revenue 24/7. Most eCommerce brands have a welcome email. Very few have the other four. Here they are.
1. Welcome Series (The Revenue Foundation)
Your welcome sequence (emails sent after someone joins your list but before their first purchase) is your highest-converting automated flow. A well-built 5-email welcome series over 7 days should convert 15-25% of new subscribers into first-time buyers. Sequence: Email 1 (immediate) -- brand story and what makes you different. Email 2 (Day 2) -- your bestselling products with social proof. Email 3 (Day 4) -- customer testimonials or UGC. Email 4 (Day 6) -- objection handling FAQ. Email 5 (Day 7) -- first purchase offer (10% off or free shipping).
2. Abandoned Cart Flow (The Biggest Revenue Recovery
On average, 70% of eCommerce carts are abandoned. A three-email abandoned cart sequence recovers 5-15% of those lost sales. Email 1: 1 hour after abandonment -- "Did something go wrong?" with cart contents shown. Email 2: 24 hours later -- social proof and top objection addressed (usually shipping cost or return policy). Email 3: 48 hours later -- scarcity or small incentive (free shipping or 5% off).
3. Post-Purchase Sequence (The LTV Multiplier)
Most brands stop communicating after the order confirmation. This is the biggest missed opportunity in eCommerce email. A post-purchase sequence does three things: reduces buyer remorse (increasing review rates), introduces complementary products (increasing average order value), and builds the habit of purchasing from you (increasing repeat rate). The sequence: Order confirmation (transactional), Shipping update, Day 3 after delivery -- "How are you getting on?", Day 7 -- cross-sell recommendation, Day 14 -- review request, Day 30 -- replenishment or next product recommendation.
4. Win-Back Flow (The Silent Revenue)
A customer who bought from you 90 days ago and has not bought again is at risk of churning. A win-back sequence re-engages them before they forget you exist. Three emails over 14 days: "We miss you" with a personalised product recommendation based on their purchase history, a stronger offer (free shipping or discount), and a final "Is this goodbye?" email with a last-chance offer. Well-executed win-back flows recover 8-12% of lapsing customers.
5. Browse Abandonment Flow (The Under-Used Conversion Tool)
Browse abandonment emails are triggered when a subscriber views a product page but does not add to cart. Unlike cart abandonment (high intent), browse abandonment captures a wider funnel stage. A single email sent 2-4 hours after browsing, showing the exact product viewed with a few alternatives, typically achieves 15-25% open rates and 2-5% click-through rates -- with minimal effort to set up.
