Scaling to Consistency and Record-Breaking Revenue

The pet portraits niche is tricky for return rates, making it the perfect retention challenge.

After a solid flow setup across the customer journey, campaigns ready to educate & engage people, and constant pop-up optimizations, we had it all in place to generate real revenue and make people come back more often.

This led to a BFCM season with +46% of the brand’s 2022 revenue and an average of 24% of revenue from email marketing in 2023.

Maximizing Customer Lifetime Value with Strategic Campaigns

The key to fine art printing is to work with artists and photographers who will print multiple artworks over time.

With this customer avatar in mind, we developed a strategy to nurture them with engaging content emails, educate them with printing technical knowledge, and convert with product launches and well-timed offers.

Tailoring our email and SMS communication to our customer avatar led to an average 52% Open Rate, a 2.1% Click-Through Rate, and over 31% of the total store revenue from retention marketing strategies.

Fly Higher with the Harpia Retention Method

After helping over 50 ecommerce brands scale their retention marketing, we’ve built a playbook that unleashes your ecommerce’s full potential.

Our methodology consists of 3 steps:

Step #1 - Klaviyo Foundation

Audit Your Existing Strategy

We start by conducting our 82-point audit to find bottlenecks and leverages we can use to unlock rapid-fire growth. Receive actionable items that generate long-term results.

We must always start with the basics.

Account Basics:

Is your Klaviyo account properly synched with your ecommerce, product feed, and pixel?

List Building: 

Are your pop-ups converting? Are you consistently running A/B tests to improve results?

Email Health:

Did you set up a private domain? Are you cleaning and suppressing unengaged subscribers?

Step #2 - Capture and Nurture Leads

Create a Journey, Not A Newsletter

Turn strangers into friends with an exciting customer journey. Capture emails with an irresistible offer, tell your story and share theirs. Convert subscribers into customers.

Craft a value-packed customer journey.

Convert Subscribers into Customers

Automated Emails: 

Are your core emails good? Do you excel at the primary flows that every leading ecommerce has?

Email Broadcasts:

Are you mailing often? Does the content always provide value to your customers?

Email Creative:

Are you getting clicks and orders from your emails? Your creative is responsible for that.

Step #3 - Retain and Maximize Lifetime Value

Maximize Value: From Leads to Fans

The real magic of retention happens when your customers become friends. Optimize your campaigns and flows based on customer feedback. Ensure your customers remain engaged, loyal, and even better – promoting your brand to others.

Provide value to receive value back.

Maximize Customer Lifetime Value

List & Segments: 

Is your list growing monthly? Do you segment subscribers to send them valuable emails?

SMS Marketing:

Do you send SMS? At the right time? Most importantly, in an effective & respectful way? 


Is your list good enough for deeper segmentation & advanced flows? Do you improve past flows?

Frequently Asked Questions

Is this for me?

This offer is for ecommerce business owners with validated brands ready to scale. If you’re dropshipping or just starting out — then this is not for you.

I’ve been burned by agencies before; why trust you?

Working with agencies is like a personal relationship. Just because you’ve been in a bad relationship before, you shouldn’t stop trying.

We’re a Klaviyo Gold Agency Partner who has worked with 50 ecommerce brands like yours for over 5 years. Give us a chance, and we know you’ll love our methodology.

Why not just hire a freelancer or do it in-house?

Hiring requires training, time, and a lot of risks. To manage a successful retention marketing program, you’ll need to hire and train an experienced team: Klaviyo specialist, email designer, copywriter, and project manager. It’s expensive, time-consuming, and risky.

Hiring a professional agency like Harpia is a shortcut to success at a fraction of the cost.

What if it doesn’t work? Do you offer a guarantee?

We only work with companies we know we can help. If we run your retention marketing audit and realize we can’t help you — we won’t work with you. Although, if we take you on as a client and you fulfill your client duties (approval and providing content), and we still don’t perform — we’ll refund you your last retainer.

We work on a month-to-month basis. You cancel anytime.
