Klaviyo Agency: where to find one?
Adopting digital marketing tools to grow your e-commerce business is no longer an option, but a necessity. Among these solutions, Klaviyo stands out as an essential email marketing platform. But to unleash its full potential, you still need to find the right Klaviyo agency… and that’s not always easy.

In this guide, discover effective methods to identify a Klaviyo agency suited to your needs: online research, customer reviews, social networks, professional recommendations. Take the time to evaluate your options and find the perfect Klaviyo agency to boost your campaigns.
Introduction
Klaviyo transforms the way brands communicate with their customers: fine segmentation, smart automations, email personalization. But the difference between "basic" use and an optimized strategy often relies on support from a specialized Klaviyo agency.
What is Klaviyo?
Klaviyo is an email automation platform designed for e-commerce. Its advantages:
- Advanced segmentation based on purchasing behaviors,
- Creation of automated scenarios (abandoned cart, post-purchase…),
- Detailed reporting to optimize your campaigns.
A client who migrated to Klaviyo saw their open rate double and a significant increase in sales thanks to a strategy led by an expert agency.
Why use a Klaviyo agency?
A Klaviyo agency doesn't just configure the tool: it designs strategies adapted to your market, continuously adjusts your campaigns, and leverages data to maximize your results. Example: a handmade jewelry store saw its revenue grow after an audit, email redesign, and advanced segmentation.
Where to look for a Klaviyo agency?
1. Google and search engines
A search for "Klaviyo agency" will give you a first shortlist. Analyze: stated expertise, case studies, certifications, and customer testimonials. One of my clients found an experienced French agency via Google that doubled their email ROI in a few months.
2. Agency websites
Scrutinize websites: portfolio, detailed client cases, Shopify integrations, growth rates generated. These indicators are worth more than simple promises.
Social networks & specialized forums
Professional networks like LinkedIn are full of active agencies and verified recommendations. Email marketing forums and specialized Facebook groups provide valuable real-world feedback. Example: an entrepreneur found her agency via a forum, which then designed a complete and profitable Klaviyo setup for her.
References & recommendations
Your professional network is also a key resource. Ask your peers: what agencies do they use? What concrete results have they achieved?
Also consult specialized directories: they group agencies by area of expertise, with ratings and customer reviews. Example: a fashion brand found its Klaviyo partner via a directory, resulting in a 3x email ROI.
Conclusion & practical advice
Finding the right Klaviyo agency takes time, but it's a decisive growth lever. Rely on customer reviews, specialized directories, your networks, and professional forums to secure your choice.
Expert tip: establish a clear brief (objectives, budget, deadlines) even before starting your search. This will save you time and help you objectively compare agencies.
