E-commerce & Retail Tips & Best Practices

Include the offer in the subject line

"30% Off All Running Shoes — Today Only" outperforms "You Won't Want to Miss This!" Be specific about the value proposition.

Check spam triggers before every send

Words like "FREE!!!", "Act Now", "Limited Time" can trigger spam filters. The tester identifies these — use alternatives.

Personalise cart abandonment emails

"Still thinking about the Nike Air Max?" with the specific product name has 2-3× higher recovery rates than generic subject lines.

Frequently Asked Questions

What open rate should e-commerce emails target?▼

Promotional emails average 15-20%. Cart abandonment emails average 40-45%. Welcome emails average 50-60%. Subject line quality is the primary lever for each.

Should e-commerce emails use urgency?▼

Yes, when genuine. "Sale ends midnight" for a real deadline is effective. Fake urgency ("Last chance!" every week) increases unsubscribes.

E-commerce subject lines with emojis see 10-15% higher open rates on average, especially for promotional emails. But test with your audience.
