Short-term (< 3 months)

You know what's fascinating? Everyone's rushing to automate their abandoned cart emails with AI, but they're making the same mistake I used to make - treating automation like it has to sound robotic.

Last month, I was working on a complete website revamp for a Shopify e-commerce client. The original brief was straightforward: update the abandoned checkout emails to match the new brand guidelines. New colors, new fonts, done.

But as I opened the old template—with its product grid, discount codes, and "COMPLETE YOUR ORDER NOW" buttons—something felt off. This was exactly what every other e-commerce store was sending. So I did something that made my client uncomfortable at first, but eventually doubled their email reply rates.

Here's what you'll learn from my contrarian approach to AI-powered abandoned cart emails:

  • Why AI templates fail when they sound like AI templates

  • The simple reframe that turned transactional emails into conversations

  • How addressing real customer pain points beats generic "you forgot something" messages

  • The 3-point troubleshooting list that became our secret weapon

  • Why adding friction sometimes creates better results than removing it

This isn't about fancy AI prompts or complex automation. It's about using AI to sound more human, not less.

Industry Reality

What every ecommerce store owner has already tried

Walk into any e-commerce marketing conference and you'll hear the same advice about abandoned cart emails. The industry has settled on what they call "best practices" that frankly, aren't that great anymore.

The Standard Playbook Everyone Follows:

  1. Product-focused templates: Show the abandoned items with high-quality images and "complete your order" buttons

  2. Discount escalation: Start with 10% off, then 15%, then 20% in a sequence

  3. Urgency tactics: "Limited time offer" and "only 3 left in stock" messaging

  4. Corporate tone: Professional, polished emails that sound like they came from the marketing department

  5. Automated sequences: Send at 1 hour, 24 hours, and 72 hours after abandonment

This conventional wisdom exists because it's measurable and feels "professional." Marketing teams love it because they can set it and forget it. The results? Mediocre at best.

Where This Falls Short: These emails treat symptoms, not causes. Most cart abandonment isn't about forgetting—it's about friction, concerns, or timing. When you send the same generic recovery email as everyone else, you're just adding to the noise.

The real problem? In 2025, everyone's inbox is full of these templated recovery emails. Customers have learned to ignore them because they all sound the same. AI has made it easier to create more of these emails, but that's exactly the wrong approach.

Who am I

Consider me as your business complice.

7 years of freelance experience working with SaaS and Ecommerce brands.

OK, so here's where things got interesting. I was working on this Shopify store revamp, and like I said, the plan was simple: update the abandoned checkout emails to match the new brand. Standard stuff.

But as I looked at their existing email template, I had this moment where I thought, "This looks exactly like every other abandoned cart email I've ever seen." Product grid, corporate language, big red "COMPLETE YOUR ORDER" button. It felt so... transactional.

The Client's Situation: This was a B2C e-commerce store with a decent customer base, but their email recovery rates were pretty mediocre. They were getting the industry average—around 15-20% open rates, maybe 2-3% click-through. Nothing terrible, but nothing exciting either.

Here's what made me pivot: during our conversations, the client mentioned that customers were struggling with payment validation, especially with double authentication requirements. Some people were hitting payment failures and just giving up instead of trying again.

My "Aha" Moment: Instead of just updating the design, what if we actually addressed the real reasons people weren't completing checkout? What if we made the email feel like it was coming from a real person who actually cared about solving problems?

What I Tried First (That Didn't Work): Initially, I thought about just adding some casual language to the existing template. You know, "Hey there!" instead of "Dear Customer." But that felt forced—like putting a smiley face sticker on a parking ticket.

The breakthrough came when I realized we were thinking about this completely wrong. We weren't trying to recover a "cart"—we were trying to help a real person who hit a roadblock while trying to buy something they wanted.

My experiments

Here's my playbook

What I ended up doing and the results.

Here's exactly what I did to transform their abandoned cart emails using AI, but in a way that made them more human, not less:

Step 1: Ditched the E-commerce Template Entirely

Instead of the traditional product grid layout, I created a newsletter-style design that felt like a personal note. No fancy graphics, no corporate headers—just clean, simple text that looked like it came from a real person.

I used AI to help me write in first person, as if the business owner was reaching out directly. The subject line changed from "You forgot something!" to "You had started your order..." Much more conversational, right?

Step 2: Address the Real Problem

This is where the magic happened. Instead of just pushing the sale, I added a troubleshooting section based on the actual friction points customers were experiencing. I used AI to help me craft clear, helpful explanations for common checkout issues.

The simple addition that changed everything was a 3-point list:

  1. Payment authentication timing out? Try again with your bank app already open

  2. Card declined? Double-check your billing ZIP code matches exactly

  3. Still having issues? Just reply to this email—I'll help you personally

Step 3: AI Prompting for Authentic Voice

Here's where AI became powerful. Instead of asking AI to "write an abandoned cart email," I gave it this context:

"Write as if you're a helpful store owner who noticed someone had trouble completing their purchase. You genuinely want to help them get what they need. Be conversational, acknowledge that checkout problems are frustrating, and offer real assistance."

Step 4: Test the "Reply-Friendly" Approach

The biggest change? I made the email feel like something you could actually reply to. Most abandoned cart emails come from no-reply addresses and sound like broadcasts. We changed that completely.

The email ended with: "If you're still interested but running into issues, just hit reply and let me know what's happening. I'm here to help make this work for you."

Step 5: Automate the Personal Touch

Using AI, I created variations of the email that could reference specific pain points based on where in the checkout process people dropped off. Cart abandoners got different messaging than payment page abandoners.

Human Connection

AI helped me write emails that sounded like they came from a real person who cares about customer success, not a marketing automation.

Problem Solving

Instead of just pushing the sale, we addressed the actual technical issues causing checkout failures in the first place.

Reply Invitation

Made emails feel conversational by using a real reply address and encouraging customers to reach out with questions.

Segmented Approach

Different email variants for different abandonment points—cart vs. checkout vs. payment issues got tailored messaging.

The Numbers That Surprised Everyone:

Within the first month of implementing this approach, we saw some pretty dramatic changes. The open rates jumped from around 18% to 31%—not shocking, since the subject lines were more human. But here's what really caught our attention:

Reply Rate Transformation: The biggest win wasn't just recovered carts—it was that customers started actually replying to the emails. We went from basically zero replies to getting 4-5 customer responses per week asking questions, sharing feedback, or requesting help.

Conversion Impact: Some people completed purchases after getting personalized help via email. Others shared specific issues we could fix site-wide. The abandoned cart email became a customer service touchpoint, not just a sales tool.

Unexpected Customer Insights: Those email replies gave us data we couldn't get anywhere else. We learned about mobile checkout issues, payment method preferences, and shipping concerns that weren't showing up in our analytics.

The most interesting result? Customer satisfaction actually improved. People appreciated feeling heard rather than just marketed to.

Learnings

What I've learned and the mistakes I've made.

Sharing so you don't make them.

Here are the key lessons I learned from breaking every "best practice" in the book:

  1. AI works best when it helps you be more human: The goal isn't to replace human connection—it's to scale it

  2. Address causes, not just symptoms: Most cart abandonment emails treat the wrong problem

  3. Conversations convert better than broadcasts: People can tell when an email is really "from" someone

  4. Friction can be your friend: Encouraging replies creates more work but builds stronger relationships

  5. Context matters more than clever copy: Understanding why people abandon is more valuable than perfecting your subject line

  6. Template fatigue is real: In a world of automated emails, sounding different is more important than sounding perfect

  7. Customer service can be marketing: Helping people solve problems builds loyalty beyond single transactions

How you can adapt this to your Business

My playbook, condensed for your use case.

For your SaaS / Startup

For SaaS companies running freemium or trial models:

  • Apply this same principle to trial expiration emails—address why people aren't upgrading, don't just push the sale

  • Use AI to create troubleshooting guides for common onboarding issues

  • Make emails feel like they come from customer success, not marketing

For your Ecommerce store

For online stores looking to implement this approach:

  • Start by identifying your top 3 checkout friction points

  • Use AI to create helpful, conversational solutions rather than sales pressure

  • Set up a real reply address and be prepared to actually help customers

  • Track replies and customer feedback as success metrics, not just conversion rates
