Why email marketing?
Email is the only marketing channel you truly own. You rent space on Meta, Google and TikTok — but your email list is yours.
Email is not an acquisition channel — it's retention and monetization.
- Acquisition: Meta, Google and TikTok bring in new customers
- Retention: Email keeps them engaged and gets them to buy again
- Monetization: Email drives repeat purchases with minimal marginal cost
Typical email contribution for mature e-commerce brands:
- 20–30% of total revenue comes from email
- 50%+ of that comes from automated flows
- The rest comes from campaigns
When should you invest in email?
Minimum prerequisites
Start with email when you have:
- 500+ email subscribers (or growing list)
- 50,000+ DKK/mo. in revenue
- Traffic to your webshop (organic or paid)
- Products people buy more than once
Without these foundations you don't have enough volume to create real ROI.
Start
- Revenue: 0–50K
- Email priority: Low
- Focus: Build list + basic welcome flow
Growth
- Revenue: 50–200K
- Email priority: Medium
- Focus: Core flows + monthly campaigns
Scaling
- Revenue: 200K–1M
- Email priority: High
- Focus: Advanced flows + segmentation
Established
- Revenue: 1M+
- Email priority: Critical
- Focus: Full lifecycle + predictive
Signs you should invest NOW
→ You have 1,000+ subscribers you're not communicating with
→ Your repeat purchase rate is under 20%
→ You have no abandoned cart recovery
→ Your customers forget you between purchases
→ You're paying to re-acquire existing customers
The 5 email flows you must have
1. Welcome Flow
- What: Automatic sequence when someone signs up to your list
- When: Immediately after signup
- Purpose: Introduce the brand, build a relationship and drive first purchase
- Structure: Welcome → brand story → bestsellers → last chance
- Benchmark: 30–50% open rate, 5–15% click rate
2. Abandoned Cart Flow
- What: Reminder when someone leaves the cart
- When: 1–24 hours after abandonment
- Purpose: Recover lost sales
- Structure: Reminder → social proof → urgency → possible incentive
- Benchmark: 5–15% recovery rate
Example:
→ 100 abandoned carts/mo. × 500 DKK AOV = 25,000–75,000 DKK/mo. in recovered revenue
3. Browse Abandonment Flow
- What: Reminder when someone browses products without adding to cart
- When: 1–24 hours after browsing
- Purpose: Push toward consideration and purchase
- Structure: Reminder → related products
4. Post-Purchase Flow
- What: Communication after purchase
- When: From order confirmation to several weeks after
- Purpose: Onboarding, reviews and repeat purchase
- Structure: Order confirmation → shipping → usage guide → review → cross-sell
- Benchmark: 5–15% review conversion rate
5. Win-Back Flow
- What: Re-engagement of inactive customers
- When: 60–90+ days after last purchase
- Purpose: Reactivate before churn
- Structure: "We miss you" → new products → incentive → last chance
- Benchmark: 5–10% reactivation rate
