Still chasing new customers while ignoring the ones who already bought from you?
In 2025, email automation isn’t a nice-to-have — it’s the backbone of customer retention.
Whether you’re making $1k/month or $100k, these 5 flows are the easiest way to boost revenue without spending a dime on ads.
Let’s dive in 👇
1. Welcome Flow (With Smart Segmentation)
🧠 Why it matters in 2025:
Your first impression now has to work smarter, not harder. With privacy updates and AI-fueled consumer behavior, people need to feel a connection — fast.
✅ What to include:
- Email 1: Welcome & brand story (set expectations, deliver lead magnet if any)
- Email 2: Bestsellers or collection intro based on what they browsed
- Email 3: Customer reviews, UGC, or social proof
- Email 4: Light offer or value reminder (free shipping, unique selling point)
💡 Real Example:
We set up a welcome flow for a pet supplement brand. Just by A/B testing the first subject line with a curiosity angle — “Is Your Pup Missing This?” — we boosted open rates from 38% to 57%. Revenue? +22% in 14 days.
✍️ Pro Tip:
Use Shopify’s dynamic customer data to show personalized products in the 2nd and 3rd emails.
2. Browse Abandonment Flow
🧠 Why it matters in 2025:
People window-shop more than ever. If someone viewed a product and left — you’ve still got a shot. Especially when you can track behaviors with Shopify Pixels and GA4 events.
✅ What to include:
- Email 1: “Still thinking about this?” with product image
- Email 2: Social proof or testimonials
- Email 3: Light urgency (low stock, price drop, etc.)
💡 Real Example:
One of our clients selling home décor saw 11.2% revenue lift in 30 days just from a 2-email browse abandonment flow — no discount needed.

3. Cart Abandonment Flow (With Embedded Video)
🧠 Why it matters in 2025:
Cart abandonment flows are a classic — but most are outdated.
In 2025, it’s all about engagement: GIFs, short videos, and emotion.
✅ What to include:
- Email 1: Product reminder with urgency and benefits
- Email 2: “See how it works” – a short video demo or lifestyle GIF
- Email 3: Offer (optional), or support CTA (chat link, contact info)
💡 Real Example:
For a skincare brand, we embedded a 7-second “how to use” video in email 2. CTR increased by 33%, and conversion rate by 19.7%.
4. Post-Purchase Flow (Retention Booster)
🧠 Why it matters in 2025:
The money is in the second and third purchase. Your job doesn’t end at “Thanks for your order.”
✅ What to include:
- Email 1: Order confirmation + “What to expect”
- Email 2: How to use / care guide
- Email 3: Product recommendation (cross-sell)
- Email 4: Request for review or referral
💡 Real Example:
We created a post-purchase flow for a fitness gear store that recommended a resistance band set after someone bought a yoga mat. Result: a 9.1% increase in repeat purchases.
✍️ Pro Tip:
Add tags like “First-time Buyer” or “VIP” to personalize future messages using Klaviyo or Omnisend.
5. Win-Back Flow (With Predictive Timing)
🧠 Why it matters in 2025:
Customer attention is shrinking. Most brands wait too long to reactivate buyers. But platforms like Klaviyo now help you predict when they’re likely to churn — so you can strike at the perfect moment.
✅ What to include:
- Email 1: “We miss you” with bestsellers
- Email 2: Exclusive discount or free shipping
- Email 3: SMS follow-up (optional but effective)
💡 Real Example:
For an activewear brand, we built a win-back flow using predicted churn data. Recovered 5.7% of lapsed customers in 3 weeks — with a 3-email + 1-SMS combo.
