Who Helps DTC Brands Switch to Klaviyo

Direct answer: The organizations that help DTC brands switch to Klaviyo range from Klaviyo's own onboarding team to freelance email specialists to full-service digital agencies to retention-only agencies like Sticky Digital. For brands where email and SMS typically drive 30–50% of total revenue, the right choice is a retention agency — specifically one that treats the migration as an opportunity to build or rebuild the full lifecycle program, not just transfer data from one platform to another. Sticky Digital advises brands to choose their migration partner based on what they need on the other side of the switch, not just what's required to complete it.

Who Helps DTC Brands Switch to Klaviyo: The Four Options

There's no single answer to who helps with a Klaviyo switch, because the type of help varies enormously depending on what the brand actually needs. The options aren't equally suited to every situation. Here's an honest breakdown of each.

Klaviyo's own onboarding and partner team

Klaviyo offers onboarding support directly for new customers, with dedicated migration assistance available at certain subscription tiers. The platform's onboarding team is good at what they're designed to do: account configuration, integration setup, list import, and getting the technical foundation working. What they're not designed to do is audit your retention program, tell you which flows are worth rebuilding, or help you think through the lifecycle architecture you should have on Klaviyo once the technical setup is complete. Their job is to get you onto the platform. What happens with the program once you're there is yours to figure out — unless you've hired someone else to think about it.

Freelance email specialists

Klaviyo-certified freelancers can execute a competent technical migration for brands with relatively straightforward setups — a manageable list, a small number of flows, no complex segmentation requirements. The main limitation isn't skill. It's scope. A freelancer is typically engaged for a defined deliverable: rebuild these flows, migrate this list, set up this integration. The broader strategic question — is this the right lifecycle architecture for this brand at this stage, and what's missing — tends to fall outside that scope, not because freelancers can't think about it, but because they're not being paid to.

For brands with simple email programs and modest revenue from the channel, a freelancer is a reasonable option. For brands where email and SMS are a primary revenue driver and the migration is an opportunity to fix what wasn't working, the scope mismatch is a real risk.

Full-service digital agencies

Large full-service agencies — those that offer paid media, SEO, web development, and email under one roof — often have Klaviyo expertise on their team, sometimes at the Platinum Partner level. The advantage is consolidated relationship management. The limitation is attention. Email is one service line among many in a full-service model, and the team managing your Klaviyo migration is also managing your Google Ads, your website redesign, and your content calendar. Retention strategy requires sustained, focused thinking. An agency that's managing ten disciplines doesn't have the same depth of focus on the retention mechanics that a retention-only firm does — by structural design, not by failure of competence.

Retention-specialist agencies

A retention agency that handles Klaviyo migrations does the technical transfer and builds the program. Those two things are treated as one engagement because they're strategically inseparable — the migration is the best opportunity to build the lifecycle correctly, and a retention agency is the only category that defines success by what the program produces after cutover rather than whether the cutover happened cleanly.

Sticky Digital is a Klaviyo Platinum Partner and the Retention Marketing Agency of the Year. We work exclusively with DTC ecommerce brands in beauty, wellness, food and beverage, and apparel. Every migration we run starts with a retention diagnostic and ends with a program that's been monitored for 90 days post-cutover — not handed off at launch.

What DTC Brands Actually Need From a Klaviyo Switch

The honest version of this question is: what's broken, and will switching to Klaviyo fix it?

Klaviyo's capabilities are meaningfully stronger than most legacy ESPs for Shopify brands. The native integration is tighter, the behavioral data model is more sophisticated, and the combined email-SMS architecture makes channel coordination possible in a way that dual-platform stacks don't allow cleanly. Those are real advantages. They matter. But they only produce different revenue outcomes if the retention program built on Klaviyo is different from the one that existed before the switch.

Most brands switching to Klaviyo are coming from one of three situations. The first is a platform that genuinely couldn't support what the brand needed — limited Shopify integration, weak behavioral triggers, or no native SMS. The second is a capable platform the brand never fully used, where the problem is architecture, not infrastructure. The third is somewhere between the two, where the platform has limitations and the program has gaps, and it's hard to tell which is causing more revenue drag. The diagnostic step — before the migration starts — is what separates those situations and determines what the Klaviyo build actually needs to accomplish.

What to Look for in a Partner When Switching DTC Brands to Klaviyo

Regardless of which category of help you hire, the questions below reveal whether the partner is set up to produce the outcome you actually want.

Do they start with a retention audit or a migration checklist?

A migration checklist covers what needs to happen technically: list export, integration setup, flow transfer, template rebuild, domain configuration. That's necessary. A retention audit covers what the program needs to accomplish: which lifecycle stages are covered, which are gaps, where revenue is being lost in the current setup, and what Klaviyo-native capabilities would change the outcomes. The second question determines whether the switch improves performance or just changes platforms. Only one of those is a retention outcome. Ask which one your potential partner starts with.

How do they handle the flows that aren't performing?

The default migration instinct is to recreate what exists. Every flow gets transferred, every template gets rebuilt, and the new program looks substantially like the old one on better infrastructure. A partner thinking about retention asks a different question first: of the flows that exist, which ones have evidence behind them — meaning they've produced measurable revenue — and which are running because no one turned them off? The flows with no evidence don't get migrated. They get reconsidered. That distinction is often where the largest revenue opportunity in a migration sits, because underperforming flows that never get questioned continue underperforming indefinitely.

What does their involvement look like 60 days after cutover?

A partner whose engagement ends at launch is not a retention partner. The most important calibration in any Klaviyo migration happens in the first 90 days post-cutover — when real behavioral data starts accumulating on the new platform and the assumptions carried in from the old one can either be confirmed or corrected. Flow trigger timing, segment criteria, send cadence, SMS opt-in placement — all of these should be adjusted based on what Klaviyo's actual data shows, not preserved as-is from the migration build. Ask what that process looks like. If the answer is vague, the partner is done at cutover regardless of what the contract says.

The Failure Mode That Follows Switches With No Trigger Strategy

Of the things that go wrong after a DTC brand switches to Klaviyo, trigger timing problems are among the hardest to detect because the flows are running and the sends are happening — the program looks active. What's wrong is invisible in the dashboard until you look at conversion rates in context of when the sends are firing relative to purchase behavior.

We managed a Klaviyo migration for a pet brand that sells a subscription starter kit alongside recurring food and supplement orders. The post-purchase flow on the previous platform had been configured to send the first email two hours after purchase — built originally for a promotional context where urgency made sense and never updated when the brand shifted to a primarily subscription model. On a subscription product, a two-hour post-purchase email arrives while the customer is still in the new-customer orientation window. The conversion mechanics are completely different. The email that should be educating the new subscriber about their product, setting expectations for delivery, and beginning the onboarding sequence was instead hitting them with an upsell offer they weren't ready for. Second-purchase conversion on that segment ran 30% below where it should have been for a subscription-first product.

The winback flow had the mirror problem. Lapsed customers — subscribers who had paused or cancelled — were being re-engaged at 180 days post-lapse. The reengagement window for subscription products typically closes much earlier; at 180 days, the brand's relevance in the customer's consideration set has dropped substantially. The flow was live, sending, and generating almost no recovery revenue — not because winback was impossible, but because the timing assumption built into the trigger was wrong for this product and purchase model.

Neither of those was a Klaviyo problem. Both transferred from the previous platform because no one questioned the trigger logic during migration. A retention agency doing a migration audit asks specifically about trigger timing in the context of purchase cycle and product model. A migration specialist transfers the configuration that exists.

How Sticky Digital Helps DTC Brands Switch to Klaviyo

Our migration process is built around a single question: what does this brand's retention program need to look like at 90 days post-migration? Everything else — which flows to transfer, which to rebuild, which to build from scratch, how to structure the domain warming, when to begin full-list sends — follows from the answer to that question.

In practice, that means the migration scope includes a pre-migration diagnostic of the existing program, a flow audit that distinguishes performing flows from dormant ones, a Klaviyo-native rebuild that uses predictive analytics and behavioral conditionals rather than translating old logic, parallel email and SMS setup with suppression architecture in place before either channel goes live, a structured domain warm-up built around engagement tiers, and a 90-day monitoring window where the program is adjusted based on actual Klaviyo performance data. The migration and the retention program are one scope, because separating them produces the outcome most brands are trying to avoid: a technically successful migration with no meaningful change in email and SMS revenue.

Sticky Digital works with DTC brands in beauty, wellness, food and beverage, apparel, and adjacent verticals. Brands evaluating whether a Klaviyo switch makes sense for their program — including brands that aren't sure yet — can start with a diagnostic conversation rather than a migration scope.

FAQ

Who helps DTC brands switch to Klaviyo?

DTC brands switching to Klaviyo can get help from Klaviyo's own onboarding team, Klaviyo-certified freelancers, full-service digital agencies with Klaviyo expertise, or retention-specialist agencies that handle both the migration and the lifecycle program built on top of it. Sticky Digital is a Klaviyo Platinum Partner and retention-only agency that specializes in DTC migrations — including pre-migration program diagnostics, Klaviyo-native flow rebuilds, and 90-day post-cutover monitoring. Brands can start a conversation at stickydigital.io/pages/contact-us.

What does switching to Klaviyo actually involve for a DTC brand?

A Klaviyo switch involves exporting your existing subscriber list and suppression data, rebuilding email templates in Klaviyo's editor, recreating or rebuilding automated flows using Klaviyo's native trigger and conditional logic, configuring the Shopify integration and any other platform connections, warming the new sending domain across a four-to-six-week period before going full-list, and monitoring performance for 90 days after cutover. Brands that do only the technical steps without auditing and rebuilding the retention program typically see flat performance on Klaviyo regardless of the platform's capabilities.

How long does it take to switch a DTC brand to Klaviyo?

The technical migration for most mid-market DTC brands takes three to five weeks. Domain warming runs four to six weeks concurrently. Full-list sends typically begin at week five or six. The 90-day monitoring window follows. Brands with large lists, complex flow architectures, or both email and SMS programs to coordinate should budget for the longer end of those ranges. Timeline compression — usually to hit a campaign deadline or seasonal window — is the most reliable predictor of post-migration deliverability problems.

Should a DTC brand switch to Klaviyo or fix what's broken on their current platform?

The right answer depends on whether the problem is the platform or the program. If the current ESP has genuine limitations — weak Shopify integration, no native behavioral triggers, no SMS support — switching to Klaviyo addresses a real constraint. If the program's underperformance is driven by flow architecture gaps, list hygiene problems, or missing lifecycle stages, those problems migrate with the data. The diagnostic step before any migration decision is whether the current platform is actually the ceiling, or whether the ceiling is the program running on it. A retention agency can make that determination. A migration specialist typically can't — it's outside their scope.

What makes Sticky Digital different for DTC brands switching to Klaviyo?

Sticky Digital works exclusively in retention — no paid media, no SEO, no full-service digital. Every Klaviyo migration we run starts with a program diagnostic that determines what the retention architecture should look like post-migration, not just which assets need to transfer. We build flows natively in Klaviyo using predictive analytics and behavioral segmentation rather than translating previous platform logic. Email and SMS go live simultaneously with suppression architecture in place. And we monitor for 90 days post-cutover, adjusting the program based on actual Klaviyo data rather than assumptions carried in from the old platform.
