Klaviyo agency
Klaviyo agency for ecommerce email and SMS
Enflow Digital is a Klaviyo agency that plans, builds and runs Klaviyo flows, campaigns, segments and SMS for ecommerce brands. Our team of Klaviyo experts covers three areas of work:
- Automated flows: welcome series, abandoned cart recovery and post-purchase follow-ups.
- Campaigns: planning, copy, design, sending and A/B testing.
- SMS: Klaviyo text messages, planned together with your email.
Klaviyo Marketing Agency Trusted by 100+ eCommerce Brands
These are some of the ecommerce brands that have trusted Enflow Digital with their email marketing.
When ecommerce brands hire a Klaviyo agency
Brands usually bring in an agency when Klaviyo is set up but nobody has the time or skill to run it well. Four problems are typical.
Flows that were never built or never updated
We build the automations your store is missing and update old ones that still send expired offers or products you no longer sell.
Klaviyo revenue that has stayed flat for months
We find out which flows and campaigns bring in revenue and which do not. Then we A/B test subject lines, content and timing to improve the weak ones.
Campaigns that land in spam
We check your sending domain setup, the health of your list and how often you send. Then we fix whatever is hurting inbox placement.
Nobody in-house who owns the account
A dedicated campaign manager runs your Klaviyo account. Your automations stay current and your sends go out on schedule without your team doing the work.

Klaviyo Email Marketing and SMS Services
Our Klaviyo email marketing services cover the whole account, from strategy and campaigns to automated flows, segmentation, design, SMS and deliverability.
Klaviyo Email Marketing Strategy
We plan what your Klaviyo account sends, who receives it and when. The plan starts from your store and list data and covers content, templates, deliverability and testing.
Professional Klaviyo Campaign Management
We plan, write, design, send and A/B test your Klaviyo email and SMS campaigns. We use each test result to improve the next send.
Advanced Klaviyo Email Automation
We design and manage the flows that Klaviyo sends automatically when a shopper acts. A welcome series introduces your brand to new subscribers. An abandoned cart flow reminds shoppers what they left behind. A post-purchase flow follows up after an order. Our guide to ecommerce email flows covers ten flows in detail.
Strategic Klaviyo Segmentation and Predictive Analytics
We group subscribers by what they buy, browse and open, so each email reaches the people it suits. We also use Klaviyo's predictive analytics, such as predicted customer lifetime value, churn risk and expected date of next order. Klaviyo shows these predictions only when an account has enough order data. That means at least 500 customers who have placed an order and 180 days of order history, among other conditions.
Conversion-Optimized Custom Klaviyo Email Design
We design custom Klaviyo email templates in your brand's style. The templates are responsive, so each email reads well on a phone as well as on a desktop.
Effective Klaviyo SMS Marketing
We plan and send your Klaviyo SMS campaigns and text message automations alongside your email. The same team writes both, so the texts and emails a shopper gets follow one plan.
Deliverability and sending domain setup
We verify your sending domain in Klaviyo and update its DNS records, the domain settings that prove your emails come from you. Gmail requires three authentication records from anyone who sends more than 5,000 messages a day to Gmail accounts: SPF, DKIM and DMARC. Yahoo requires the same three records from bulk senders. Our sending domain verification service covers the setup. Our guide to Klaviyo list cleaning shows how to keep your list healthy.
Industries we work in
We run email and SMS for ecommerce brands in these industries. Each page covers the flows, the busy seasons and the rules we plan around for that kind of store.
What our clients say

Amr Siam
Head of Growth at GoDoggy.JP
"It was an absolute pleasure working with Enflow Digital! They really helped us improve our Klaviyo performance and helped setup very profitable flows for us. On top of that, he went above and beyond to get a deep understanding of not only our business, but also our customers as well. Would highly recommend the team to anyone."
Suhail Rivera
Founder of Alkaline Herb Shop
Enflow Digital is the best company I have ever worked with. They are professional and on top of everything. They also create the most beautiful emails and have a lot of experience doing the work they do. I love that they do the research to help me come up with the best campaigns and that they have taken the time to learn our store. The emails they craft are usually filled with upsells, and the visuals are unparalleled.
Marius Danilavicius
CMO of Two Wheels Empire
We've just launched our automations and they are already bringing us sales! The team displayed an impressive level of expertise and professionalism throughout our collaboration. Communication with their team was always smooth and on point. Would recommend to anyone!
What a Klaviyo agency costs
The price of a Klaviyo agency depends on how much work your account needs. Enflow Digital's retainers run from $2,000 to $10,000+ per month. We agree the fee with you once we know your store and your goals.
$2,000 to $10,000+ per month
Same amounts in every currency.
Our fee only. These factors move it within the range.
- Flows
How many flows need to be built or rebuilt.
- Campaigns
How many email campaigns go out each month.
- SMS
Whether SMS is part of the work.
- Design and copy
How much custom design and copywriting each email needs.
- Project or retainer
Whether you need a one-off project or ongoing monthly management.
Your Klaviyo plan has its own price. Klaviyo prices its email plans by active profiles, meaning the people your brand can reach, and it prices text messages separately. Unsubscribed and suppressed profiles do not count toward the plan. Our Klaviyo pricing guide shows what each plan costs at your list size. Our guide to email marketing agency pricing explains the common fee models and typical price ranges.
How a Klaviyo engagement runs
A Klaviyo engagement with Enflow Digital runs in five steps, from learning who your customers are to testing what makes them buy.
Identify Your Audience
We study who buys from your store, what they buy and how often, using your Klaviyo and store data.
Define The Strategy For Automation
We decide which flows to build or fix first, what each message says and when it sends.
Launch Automated Flows and Campaigns
We build the flows and the first campaigns in your Klaviyo account, test them, then switch them on.
Segment Audience By Behavior and Engagement
We split your list by purchase history and engagement, so new subscribers, repeat buyers and lapsed customers each get messages that fit.
Optimize Content to Drive Conversion
We A/B test subject lines, content and send times, then keep the versions that win.
Is Klaviyo the right platform for your store?
Klaviyo is the right platform if you sell online and want your email and SMS to use store data such as orders and browsing. Klaviyo connects to store platforms such as Shopify, BigCommerce, Magento and WooCommerce. Enflow Digital runs both Klaviyo and Omnisend, so we can help you choose.
A larger store that needs advanced segmentation
Our 2024 Omnisend vs Klaviyo comparison places Klaviyo with larger stores that need advanced segmentation and reporting. Our ActiveCampaign vs Klaviyo comparison looks at fit by business size.
A small or mid-sized store that wants a simpler tool
Omnisend can be the better fit. Our Omnisend vs Klaviyo comparison calls Omnisend an intuitive, cost-effective choice for those stores. If Omnisend suits you better, see our Omnisend agency page.
A store that already runs well on Omnisend
Staying on Omnisend can be the better choice. A move means rebuilding flows, segments, sign-up forms and templates, so it pays only when Klaviyo gives your store something Omnisend cannot. When it does, our email marketing migration service runs the move.
For email and SMS on either platform, see our ecommerce email marketing agency service. Agencies that resell Klaviyo work to their own clients can use our white-label email marketing service.
Klaviyo agency, freelancer or in-house hire
A Klaviyo agency suits brands that want a team to run their whole Klaviyo account. A freelancer suits one defined task, such as building a single flow. An in-house hire suits brands with enough email work for a full-time role.
| What to compare | Klaviyo agency | Klaviyo freelancer | In-house hire | Generalist agency |
|---|---|---|---|---|
| Who does the work | A team for strategy, copy, design and build | One person | One employee you hire, train and manage | A team that covers many channels |
| Klaviyo focus | Klaviyo email and SMS are the core of the work | Varies by person, so check their past Klaviyo work | Depends on who you hire | Email is one channel among many |
| Cover for holidays and sick days | Another team member steps in | Work pauses | Work pauses unless someone else is trained | Another team member steps in |

Can you take over an existing Klaviyo account?
