How We Selected These Klaviyo Experts

Every expert featured here has gone through GrowTal’s structured vetting process, which includes skills-based assessments and direct reference checks.

Meet the Top Klaviyo Marketing Experts

Nicolas Duminil

Strategy (Interim CMO / Head of Growth) & Paid Social Advertising

With more than 15 years of marketing leadership across Paris and New York, Nicolas works at a strategic level rather than a task level. His experience spans digital strategy, growth, product, and community building, which fits ecommerce brands and apps that need someone to connect email and retention to a broader growth plan. He has worked across ecommerce, B2B, real estate, food, and travel, so he can adapt a Klaviyo strategy to the specific revenue model and customer lifecycle of a given business. Founders who need an interim head of growth to own the full retention roadmap, not just manage individual flows, will find his scope directly relevant.

Email Marketing, Paid Social (Facebook), CRO & Branding

Natalia’s background spans both institutional and high-growth environments, with roles at General Electric, Techstars, CFTE, and the Embassy of the Republic of Poland. That mix gives her operational discipline alongside startup-pace execution. Her core work in email marketing is complemented by experience in paid social and CRO, which helps brands that want their Klaviyo campaigns working in coordination with acquisition channels rather than in isolation. With four-plus years of hands-on experience managing and executing campaigns, she suits teams that need a capable email marketer who can also think through how email fits the wider conversion funnel.


Tiffany Broden

Email Marketing & Automation

Nine years of email marketing have given Tiffany deep platform expertise in Eloqua and Salesforce Marketing Cloud. Those tools demand a level of technical rigor that carries over well to building reliable Klaviyo automation. She works comfortably in HTML and CSS, so she can go beyond template-based builds when email design or rendering precision matters. Her experience with A/B testing and email analytics means she treats campaigns as something to measure rather than set and forget. She has shown results with fitness brands and B2B companies, which makes her a practical option for businesses in those spaces looking to tighten their lifecycle email programs.

Creative & Email Design, Product Marketing

Ignacio works at the intersection of creative design and product marketing, a good fit for brands that need their Klaviyo emails to do more than deliver a message. They also need to reflect a coherent visual identity and drive action. His background spans ecommerce, hospitality, marketing services, and signage, so he has designed for audiences with very different expectations and buying contexts. For teams that already have the copy and strategy in place but need someone to raise the design execution and keep creative consistent across templates, he fills a specific and often underserved gap on a retention team.

How to Choose the Right Klaviyo Expert for Your Store

Start by naming the specific problem you want solved, because Klaviyo work splits into fairly distinct skill sets. If your flows are broken or your segmentation is a mess, prioritize someone with hands-on automation depth like Tiffany. If your emails convert poorly because they look generic, a design-led specialist like Ignacio matters more. When email needs to plug into paid acquisition and conversion work, look for someone who thinks across channels, and when the whole retention roadmap needs an owner, a growth strategist is the better call. Ask candidates how they would approach your existing account before you commit, and use a short pilot to confirm the fit against real data rather than a portfolio alone.

Our Simple Engagement Process

Working with GrowTal starts with a two-minute brief where you describe your email and retention goals, team setup, and timeline. From there, a matchmaking call helps sharpen scope, covering what kind of Klaviyo expertise you actually need, what engagement model fits, and what a successful outcome looks like. Within 48 hours, you receive a shortlist of two to five vetted candidates matched to your brief. Once you select someone, onboarding moves quickly with a risk-free pilot sprint that lets you validate the fit before making a longer commitment.

The GrowTal Advantage

GrowTal’s core advantage is that every expert has already cleared a multi-step vetting process before they appear on any shortlist. They are skills-tested and reference-checked, not just self-selected. Engagements are available hourly, part-time, or full-time with no hidden fees, so you can right-size the commitment to what your program needs today. Coverage spans all major marketing disciplines, which means that when your Klaviyo work connects to paid social, CRO, or content strategy, you can hire across those functions through the same vetted pool. And if the first match does not work out, GrowTal provides a free rematch rather than leaving you to restart the search from scratch.

Conclusion

Klaviyo is a powerful platform, but its impact depends almost entirely on the strategy, automation logic, and creative execution behind it. The four experts profiled here represent different entry points into that work: senior growth leadership with Nicolas Duminil, email execution and channel integration with Natalia Slota, technical automation depth with Tiffany Broden, and design-focused execution with Ignacio Correia. If you also need support in adjacent areas, GrowTal can help you hire community manager talent for retention and engagement programs, find a content strategy consultant to strengthen the editorial layer of your email program, or hire lead gen specialist expertise to connect your acquisition and lifecycle efforts. Whichever gap you are filling, the right starting point is a clear brief and a shortlist of proven people. Hire vetted experts through GrowTal! and get matched with the right Klaviyo experts for your program.

Frequently Asked Questions

What do Klaviyo experts actually do that a general email marketer does not?

Klaviyo-specific expertise involves platform-native skills like building conditional flow logic, managing list and segment hygiene at scale, using predictive analytics, and integrating Klaviyo with ecommerce data sources like Shopify. That goes well beyond general email copywriting or campaign management. A generalist can write a good email. A Klaviyo expert knows how to build the system that sends the right email to the right person at the right moment based on behavior data.

When should a business hire a freelance Klaviyo expert rather than an agency?

A freelance expert usually makes more sense when you need focused execution on a specific problem, such as rebuilding a welcome flow, auditing segmentation, or improving deliverability, without paying for an agency’s overhead and account management layers. Agencies tend to add value when a brand needs full-service retention marketing with multiple contributors. For many ecommerce businesses at the growth stage, a skilled freelance Klaviyo expert paired with internal marketing ownership is the more cost-effective model.

How long does it typically take to see results from a Klaviyo engagement?

That depends on where you start and what is being built. Fixing broken flows or launching a basic welcome and abandonment sequence can show revenue impact within the first few weeks. More foundational work, like rebuilding segmentation architecture, repairing a poor sender reputation, or redesigning templates, takes longer to show measurable lift. It is reasonable to plan for a 60-to-90-day window before you have meaningful performance data on any significant changes.

What information should I have ready before briefing a Klaviyo expert?

Come prepared with your current ESP setup and any existing Klaviyo account access, your list size, and basic health metrics like open and click rates, the ecommerce platform you run on, and a rough sense of monthly email-attributed revenue if you know it. Be clear on the primary goal too, whether that is increasing flow revenue, improving campaign performance, growing the list, or something else. The more specific the brief, the faster a good match can be made and the sooner a pilot sprint can produce useful results.
