Product Recommendation Strategies
Using data to suggest the right products.
Types of Recommendations
Based on Browse History: "You recently viewed..." "Still interested in...?"
Based on Purchase History: "You might also like..." "Customers who bought X also bought..."
Based on Category Affinity: "More from [category]..." "New in [their favorite category]"
Based on Customer Segment: "Popular with customers like you..." "Top picks for [segment]"
Recommendation Best Practices
Relevance Over Random: Generic "bestsellers" perform worse than personalized recommendations.
Show Social Proof: Include ratings, reviews, "X people bought this" signals.
Limit Choices: 3-6 products per email. Too many options reduce clicks.
Fresh Products: Mix new items with recommendations based on history.
Cross-Sell and Upsell
Cross-Sell (Complementary Products):
- Bought shoes? Suggest socks, shoe care
- Bought camera? Suggest cases, lenses
- Bought dress? Suggest accessories
Upsell (Higher-Value Alternatives):

Measuring E-commerce Email Performance

RPE = Total Email Revenue / Emails Sent
Revenue Per Subscriber:
Revenue Per Sub = Total Email Revenue / Total Subscribers
Percentage of Total Revenue:
Email Revenue % = Email Revenue / Total Revenue × 100
Automation Performance

Benchmark Your Automations:
| Automation | Good | Excellent |
|---|---|---|
| Welcome Conversion | 5-10% | 15%+ |
| Cart Recovery | 5-10% | 15%+ |
| Win-back Success | 5-10% | 15%+ |

- Open-based: 1-3 days
- Consider your typical purchase cycle
Common E-commerce Email Mistakes
Avoid these pitfalls.
Mistake 1: Too Many Promotional Emails
Problem: Every email is "SALE!" Subscribers tune out. Fix: Balance promotional with value-add content (80/20 rule inverted for e-commerce: 60% promo, 40% value).
Mistake 2: Poor Product Imagery
Problem: Blurry, small, or poorly lit product photos. Fix: Invest in professional product photography. Images sell.
Mistake 3: No Personalization
Problem: Same email to everyone, ignoring purchase history. Fix: Use purchase data for relevant recommendations.
Mistake 4: Ignoring Abandoned Carts
Problem: No cart recovery automation. Fix: Implement cart abandonment sequence immediately—it's free money.
Mistake 5: Missing Post-Purchase Opportunity
Problem: Only order confirmation, no follow-up. Fix: Build full post-purchase sequence including reviews and repeat purchase.
Mistake 6: Bad Mobile Experience
Problem: Emails that don't work on phones. Fix: Mobile-first design, test on actual devices.

Data Quality for E-commerce
Invalid emails mean lost revenue.
The E-commerce Impact
At Checkout: Invalid email = No order confirmation = Customer anxiety = Support calls
For Marketing: Invalid emails = Bounces = Deliverability damage = Lower inbox placement for everyone
For Revenue: Customers you can't email = Lost repeat purchase opportunity
Verification Points
At Account Creation: Verify before creating account with email verification. Prevent problems before they start.
At Checkout: Verify guest checkout emails using our email checker tool. Ensure order confirmation arrives.
List Hygiene: Regularly verify your customer email list with bulk email verification. Remove invalid addresses and maintain email list hygiene.
ROI of Verification

- Average email revenue: $0.50 per subscriber
- Monthly sends: 4
- Lost revenue: 500 × $0.50 × 4 = $1,000/month
Plus deliverability protection for the 9,500 good addresses. Learn more about email deliverability optimization and protecting your sender reputation.
