Klaviyo Agency: how to choose the right one
Summary
Are you already using Klaviyo or are you interested in this marketing automation tool? Choosing a specialized Klaviyo agency is a crucial step to turn your campaigns into real growth drivers.

Introduction
Klaviyo is now one of the most powerful tools in email & SMS marketing. However, according to the Klaviyo Benchmark 2024, less than 40% of brands fully exploit its potential. Hence the importance of calling on a certified Klaviyo agency to maximize your ROI.
Why choose a Klaviyo agency?
Even though Klaviyo is designed to be intuitive, its advanced features (behavioral segmentation, automation, reporting) require specialized expertise. A specialized agency allows you to:
- Create profitable automated scenarios (abandoned cart, retargeting, loyalty).
- Personalize your email and SMS campaigns according to customer behavior.
- Analyze your data to make ROI-driven decisions.
- Ensure continuous support and strategic updates.
Defining your needs and objectives
Before looking for an agency, clarify your marketing priorities. Do you want to: increase your open rates? boost your conversions? improve customer loyalty? integrate Klaviyo with Shopify or WooCommerce?
Anecdote: an e-commerce SME I coached had a clear objective: segment its customers and personalize its campaigns. Result: +35% click-through rate in 3 months.
How to research and compare agencies
A simple search for "Klaviyo agency" yields dozens of results. To avoid mistakes:
- Check their client references.
- Analyze their technical skills in marketing automation.
- Compare their ability to integrate Klaviyo into your ecosystem (Shopify, WooCommerce, etc.).
Concrete case: a retail company hastily chose a non-specialized agency. Result: missed deadlines and disappointing ROI. After switching to an expert Klaviyo agency, their conversions jumped by +50%.
Evaluating proposals and pricing
Don't just focus on the price. Ask for several free consultations and compare:
- The clarity of recommendations.
- The relevance of the proposed solutions.
- The responsiveness and availability of the team.
A comparative table (objectives, prices, deadlines) is an excellent tool for evaluating Klaviyo agencies rationally.
Making the right choice of Klaviyo agency
The right Klaviyo agency should be a strategic partner, not just a technical service provider. It must:
- Understand your business objectives.
- Be proactive in its recommendations.
- Provide transparent and actionable reporting.
In short: prioritize expertise and communication over merely focusing on the budget.
