Running an ecommerce store is no easy task. Between managing inventory, handling customer service, and running ads, marketing often becomes overwhelming. That’s where a Klaviyo marketing agency steps in.
Instead of leaving your email and SMS marketing on autopilot (or ignoring it completely), a Klaviyo agency helps you unlock hidden revenue, build customer loyalty, and scale your brand without relying solely on paid ads.
In this guide, we’ll explore what a Klaviyo marketing agency does, why it’s essential for ecommerce growth, and how to pick the right one for your business.
What is a Klaviyo Marketing Agency?
A Klaviyo marketing agency is a team of experts who specialize in email and SMS marketing using Klaviyo’s powerful platform. They don’t just send emails—they build automated systems that generate sales 24/7.
Think of them as your ecommerce growth partner: they set up personalized customer journeys, optimize campaigns, and make sure your messages land in inboxes, not spam folders.

What Services Do Klaviyo Marketing Agencies Offer?
A great Klaviyo marketing agency provides a full stack of services:
1. Klaviyo Account Setup & Migration
Switching from Mailchimp or Omnisend? Agencies handle migrations without losing data or customers.
2. Automated Email Flows
Core flows they build include:
-
Welcome series
-
Abandoned cart recovery
-
Browse abandonment

Post-purchase follow-ups
-
Win-back sequences
3. Campaign Management
They plan, design, write, and schedule promotional campaigns (holiday sales, new launches, etc.).
4. Deliverability Optimization
Agencies ensure your emails pass spam filters with domain authentication and list hygiene.
5. SMS Marketing
They integrate SMS alongside email for higher engagement.
6. Reporting & Analytics
Clear data on open rates, CTR, conversions, and revenue performance.
Why Hire a Klaviyo Marketing Agency?
1. Save Time
Running an ecommerce brand takes enough of your attention. Agencies take email and SMS off your plate.
2. Unlock Hidden Revenue
Most brands only make 10–15% of sales from email. With a Klaviyo marketing agency, that can jump to 30–40%.
3. Access to Experts
You’re not just hiring one person—you’re getting a strategist, copywriter, designer, and analyst in one package.
4. Better ROI Than Ads
Unlike paid ads that vanish when you stop spending, email flows generate revenue consistently.
Signs You Need a Klaviyo Marketing Agency
-
You don’t have a welcome flow or abandoned cart sequence.
-
Email contributes less than 20% of your total sales.
-
Your campaigns are inconsistent or rushed.
-
Emails often end up in spam folders.
-
You’re scaling fast but don’t have the time or expertise to manage email.
If any of these sound familiar, you’ll benefit from hiring an agency.
How Much Does a Klaviyo Marketing Agency Cost?
Pricing varies depending on the agency and services offered:
-
Setup & Migration: $1,500 – $5,000
-
Monthly Retainers: $2,000 – $10,000+
-
Project-Based Campaigns: $1,500 – $8,000
While it may sound expensive, the ROI is massive. If one abandoned cart flow recovers $30K in lost sales yearly, the cost is worth it.
