Here's a number that should make you uncomfortable: the average ecommerce brand drives only 15-20% of revenue from email. Top performers? 30-40%. That's the difference between surviving and thriving.
The gap isn't about sending more emails. It's about sending the right emails, at the right time, to the right people. And that comes down to flows—automated sequences triggered by customer behavior.
Let's build the flows that print money.

Based on industry benchmarks for optimized ecommerce email programs.
The Flow Stack Every Ecommerce Brand Needs
Not all flows are created equal. Here's what you need, in order of revenue impact:
1. Welcome Series (Expected Revenue: 20-30% of flow revenue)
The welcome series isn't just a "thanks for subscribing" email. It's your best chance to convert a subscriber into a customer while their intent is highest.
The flow structure:
- Email 1 (Immediate): Welcome + brand story + discount code
- Email 2 (Day 2): Social proof + best-seller spotlight
- Email 3 (Day 4): Education content + product benefits
- Email 4 (Day 6): Urgency + expiring discount reminder
- Email 5 (Day 8): Final reminder + alternative offer
Key metrics to hit:
- Open rate: 50%+ (first email)
- Click rate: 8%+ (average across series)
- Conversion rate: 8-12% (subscribers to first purchase)
Quick Win: Add SMS to your welcome flow. Brands see 30-50% higher conversion when combining email + SMS.
2. Abandoned Cart (Expected Revenue: 15-25% of flow revenue)
70% of online carts are abandoned. Most brands recover 3-5%. Top performers recover 15-20%.
The flow structure:
- Email 1 (1 hour): Simple reminder + cart contents
- Email 2 (24 hours): Address objections + social proof
- Email 3 (48 hours): Create urgency + potential incentive
- SMS (4 hours): Short reminder with direct link
What kills abandoned cart recovery:
- Waiting too long to send (the window is 1-4 hours)
- Generic copy that doesn't address why they abandoned
- No urgency or incentive
- Missing product images
What 15%+ recovery looks like:
- Personalized subject lines with product names
- Cart value segmentation (high AOV gets different treatment)
- Dynamic content showing exact cart contents
- Smart incentive strategy (don't give discounts if they don't need them)
3. Browse Abandonment (Expected Revenue: 10-15% of flow revenue)
Someone viewed products but didn't add to cart. They're interested but not convinced.
The flow structure:
- Email 1 (2 hours): "Still thinking about [product]?" + product images
- Email 2 (24 hours): Reviews/testimonials for viewed products
- Email 3 (72 hours): Related products or category spotlight
Pro tip: Segment by browse depth. Someone who viewed 5+ products is hotter than someone who viewed 1. Treat them differently.
4. Post-Purchase (Expected Revenue: 15-20% of flow revenue)
The post-purchase experience determines whether you get a one-time customer or a repeat buyer. Most brands completely neglect this.
The flow structure:
- Email 1 (Immediately): Order confirmation (make it delightful)
- Email 2 (Day 3): Shipping notification + what to expect
- Email 3 (Day 7): Product education + usage tips
- Email 4 (Day 14): Review request
- Email 5 (Day 30): Cross-sell or replenishment reminder
What great post-purchase flows do:
- Reduce buyer's remorse
- Increase product usage (critical for consumables)
- Generate reviews and UGC
- Set up the next purchase
5. Win-Back (Expected Revenue: 5-10% of flow revenue)
Re-engaging lapsed customers costs 5-7x less than acquiring new ones. Yet most brands don't have a win-back flow.
The flow structure:
- Email 1 (90 days since last purchase): "We miss you" + what's new
- Email 2 (120 days): Exclusive win-back offer
- Email 3 (150 days): Final attempt + survey
- Sunset (180 days): Remove from main list if no engagement
The win-back mindset shift: You're not trying to get every lapsed customer back. You're trying to identify who's still winnable and who's gone forever. The 180-day sunset is as important as the re-engagement emails—it protects your deliverability.
Advanced Flow Strategies
Once you have the basics, here's what separates good from great:
Segment Everything
Don't send the same abandoned cart email to a first-time visitor and a VIP customer. Segment by:
- Purchase history: First-time vs repeat buyers
- AOV: High-value vs standard customers
- Engagement: Active subscribers vs going cold
- Product category: What they buy tells you what they need
Dynamic Content > Static Templates
Your emails should look different for every subscriber. Use dynamic blocks for:
- Product recommendations based on browse/purchase history
- Location-based shipping and timing
- Loyalty points/status
- Recently viewed items
Test Flow Timing Relentlessly
The difference between 1-hour and 4-hour abandoned cart timing can be 50% recovery rate difference. Test:
- Time delays between emails
- Day-of-week for each message
- Time-of-day sends
The Benchmarks That Matter
Here's what good looks like:
Flow Performance Benchmarks
| Feature | Flow | Open Rate | Click Rate | Revenue per Recipient |
|---|---|---|---|---|
Welcome Series | 50-60% | 10-15% | $1.50-3.00 | |
Abandoned Cart | 40-50% | 8-12% | $5-10 | |
Browse Abandon | 35-45% | 5-8% | $1-2 | |
Post-Purchase | 60-70% | 8-12% | $0.50-1.50 | |
Win-Back | 25-35% | 3-5% | $0.25-0.75 |
If you're significantly below these benchmarks, you have low-hanging fruit to capture.
The Tech Stack
You need:
ESP: Klaviyo, Attentive, or Drip for ecommerce. If you're on Mailchimp, you're leaving money on the table.
SMS: Integrated with your ESP (Klaviyo, Attentive, or Postscript).
Reviews: Stamped, Loox, or Yotpo to feed social proof into flows.
Loyalty: Smile.io or LoyaltyLion to add point balances and status to emails.
