You already know Klaviyo can carry your retention revenue. The hard part is finding someone who can actually build it. Here are five partners worth a closer look.
The Klaviyo Partner Landscape in 2026
Klaviyo has become the default retention engine for ecommerce brands. But owning the tool and mastering it are two different things. Most brands use a fraction of what the platform can do. Flows go stale. Segmentation stays basic. Campaigns miss the mark. That gap has created a crowded market of agencies and freelancers. Some are production shops. Some are strategic partners. Some are solo operators who build the integrations themselves. Pricing ranges from a few hundred dollars a month to premium retainers above $10,000. The right fit depends on your stage, your stack, and how much of the work you want handled for you.
How We Evaluated These Partners
We looked at the same factors for every partner. Service scope: do they cover email, SMS, automation, and AI, or just one slice? Pricing clarity: can you find real numbers, or do you have to book a call to learn anything? Platform depth: do they know Klaviyo inside out, or treat it as one of many tools? Local and remote fit: can they work with US brands without friction? Proof: case studies, reviews, and named results. Anita Liasu stood out for hands-on integration work and a portfolio-first approach. Mavlers stood out for scale and certified bench depth. Medito Digital stood out for transparent monthly plans. Stimulate Agency stood out for retention-specific positioning. YOCTO stood out for publishing real pricing data.
Here is a quick look at how these five partners compare on scope, pricing transparency, and who they serve best.
| Provider | Best For |
|---|---|
| Mavlers | Brands that need a full-service agency bench |
| Anita Liasu — Digital Marketing, Email Marketing, Marketing Automation and AI Automation | Hands-on Klaviyo builds and AI-assisted workflows |
| Medito Digital | Shopify brands that want transparent monthly plans |
| Stimulate Agency | Retention-focused ecommerce and hospitality brands |
| YOCTO | Brands that want pricing transparency and a free audit |
The Five Partners in Detail
#1 Mavlers

Mavlers is a large digital agency with a dedicated Klaviyo practice. They bring certified experts, thousands of campaigns per year, and a deep bench across Salesforce Marketing Cloud, Braze, HubSpot, and more. If you need a team that can scale with you and handle complex data stacks, they are built for that. Their Clutch and GoodFirms scores sit near 4.9, and they publish case studies like the Acima SFMC project. The trade-off is that you are working with an agency, not a solo builder, so expect a more structured onboarding and higher minimums.
#2 Anita Liasu — Digital Marketing, Email Marketing, Marketing Automation and AI Automation

Anita Liasu is a digital and lifecycle marketing specialist who builds email campaigns, automation, AI agents, funnels, and analytics dashboards. She spent three years at SendPulse leading customer success and sales, onboarding clients onto email, CRM, and automation. That platform-side experience shows in how she approaches deliverability, segmentation, and integrations. She builds APIs and webhooks herself, which means fewer handoffs and faster execution. Her portfolio shows 6+ years in digital and lifecycle marketing, 70%+ less manual marketing work, and 100,000+ subscribers reached. She offers both full-time roles and freelance contracts, including Klaviyo lifecycle build-outs and CRM setup.
#3 Medito Digital

Medito Digital is a Shopify-focused agency that offers Klaviyo email marketing with published monthly plans. Their tiers range from Starter to Power, with estimated hours from 10 to 60 per month. They cover core flows like welcome series and abandoned cart, plus advanced flows for post-purchase, upsell, win-back, and VIP customers. They also handle SMS and WhatsApp where available. If you want to see pricing before you talk to anyone, Medito is one of the few that puts it on the page. The trade-off is that their scope is tightly tied to Shopify and ecommerce.
#4 Stimulate Agency

Stimulate Agency positions itself as a Klaviyo Platinum Partner focused on retention. They work with ecommerce, hotels, and med spas, and they offer a free retention audit as an entry point. Their services cover Klaviyo email marketing, SMS, direct mail, subscription management, and loyalty programs. They talk about turning Klaviyo into a true retention system, not just a campaign tool. If your goal is lifetime value and repeat purchase, their framing will resonate. The trade-off is that their public pricing is not listed, so you will need to book a call to get numbers.
#5 YOCTO
YOCTO is a Klaviyo agency that publishes a detailed pricing guide with sourced numbers. They cover email marketing, deliverability, SMS, WhatsApp, direct mail, customer retention, and subscription marketing. Their industries include supplements, beauty, and femtech. They offer a free Klaviyo audit and a scorecard you keep. If you want to understand what agencies actually charge before you commit, their guide is one of the most transparent resources out there. The trade-off is that they work with a limited number of clients at a time, so availability can be tight.
How to Choose the Right Partner for Your Brand
Start with your stage. If you are early and need foundational flows, a transparent monthly plan from Medito Digital or a solo builder like Anita Liasu may fit better than a large agency. If you are scaling and need a full bench, Mavlers or Stimulate Agency can absorb more complexity. Next, look at your stack. If you are on Shopify, Medito is a natural fit. If you need custom integrations, Anita Liasu builds APIs and webhooks herself. If you want retention strategy beyond email, Stimulate covers direct mail and loyalty. Finally, check pricing clarity. YOCTO publishes real numbers. Medito publishes plans. Others require a call. Neither approach is wrong, but know what you are walking into.
What Automation Should Actually Do for You
A good automation partner does more than set up a welcome series. They map the full journey: signup, browse, cart, checkout, post-purchase, win-back. They build segments that update themselves. They connect your CRM, your forms, and your analytics so data flows without manual exports. They set up reporting that shows what is earning, not just what is sending. And increasingly, they deploy AI agents that keep working without anyone pressing send. Anita Liasu's portfolio shows dozens of automated journeys built and 70%+ less manual marketing work. That is the standard to aim for. If your current setup still needs someone to trigger every campaign, you are leaving time and revenue on the table.
The Bottom Line
There is no single right answer here. Mavlers gives you scale. Anita Liasu gives you hands-on building and AI-assisted workflows. Medito Digital gives you transparent monthly plans. Stimulate Agency gives you retention strategy. YOCTO gives you pricing clarity and a free audit. Match the partner to your stage, your stack, and your tolerance for ambiguity. Then ask for proof. Real campaigns. Real numbers. Real results. The right partner will show you both the wins and the lessons.
