Klaviyo Agency That Actually Gets Opens
You are on Klaviyo because it is powerful. We are here because most accounts use about a fifth of it, and the rest of the revenue is sitting in flows that were never built.
We do three things, in this order
The order is the whole method. Most Klaviyo engagements start with campaign design because that is the part clients can see. It is also the part that matters least. A beautifully designed campaign sent from an unauthenticated domain to a list full of people who stopped caring two years ago is an expensive way to reach the promotions tab.
1. Make the email arrive
A dedicated sending subdomain, SPF, DKIM and DMARC published and aligned, bounce and complaint suppression turned on, and anyone who has ignored you for six months moved out of the active list. This is unglamorous and it is usually where the missing revenue is. There is no point optimising a subject line that lands in spam either way.
2. Build the flows
Flows run on traffic you already have and they keep running after the engagement ends. On a healthy account they out-earn campaigns roughly two to one while accounting for a small fraction of the sends. Eight of them cover almost every eCommerce business, and they are listed below.
3. Send campaigns to segments
Only once the first two are done. Campaigns go to people with a reason to receive them, starting with your engaged segment and expanding out, rather than to everyone on the list because the calendar said Tuesday.
The eight flows we build
Almost every eCommerce brand needs these eight and no more. If an agency proposes twenty, ask which ones will still be earning in a year.
Welcome
The highest earning flow on almost every account, and the one most brands treat as a single discount email. Five emails over ten days: what you make, why it exists, the objection that stops people buying, proof, then the offer. The discount goes last because anyone who was going to buy at full price has already had four chances.
Abandoned checkout
Three emails at one hour, twenty four hours and seventy two hours. The first is a reminder with the cart contents, no discount, because a large share of these people were simply interrupted. Discounting the first email trains customers to abandon deliberately, which is a habit you cannot untrain.
Browse abandonment
Triggered on a product view with no add to cart. Lower intent than checkout abandonment, so the tone is different: this is a nudge, not a recovery. Excluded for anyone already in the checkout flow, which is the single most common misconfiguration we find in existing accounts.
Post purchase
Shipping confirmation is a transactional email people actually open, so it is the best real estate you own. Then setup or usage guidance timed to delivery, then the review request once they have had the product long enough to have an opinion.
Replenishment
For consumables and subscriptions. Timed to the actual consumption cycle of the specific product someone bought, not a blanket thirty day reminder. Klaviyo knows what they ordered and when, so a coffee reorder and a supplement reorder should not fire on the same schedule.
Win back
Fires when someone passes roughly twice their expected purchase interval. The mistake here is treating a lapsed VIP the same as someone who bought once during a sale. Different segments, different offer, and one of them should not get a discount at all.
VIP and loyalty
Built on predicted lifetime value rather than a single order total. Klaviyo calculates this natively and most accounts never use it. Your top five percent of customers should not be receiving the same campaigns as everyone else.
Sunset
The flow nobody wants and every account needs. People who have not opened in ninety to a hundred and eighty days get one last attempt, then they come off the active list. This is a deliverability flow disguised as a marketing flow, and it is why the other seven keep working.
Deliverability on Klaviyo specifically
Klaviyo puts most senders on shared IP pools. That means your inbox placement depends partly on the behaviour of the other brands in your pool and mostly on your own engagement rates, which is the part you control. Brands on shared IPs sometimes assume placement problems are Klaviyo's fault. Usually they are not.
The three causes we find most often, in order. First, no dedicated sending subdomain, so you are sending from a shared Klaviyo domain and inheriting a reputation you did not build. Second, sending to the full list every time, which tanks engagement rates and teaches Gmail that your mail is ignorable. Third, a list import that should never have happened, usually from a previous platform or a trade show.
None of these are quick fixes and none of them are difficult. They just require someone to look at the account and say which one it is before spending money on the others. If you want to check your own setup first, the free deliverability audit runs fifteen checks and takes about ten minutes.
Using the data Klaviyo already has
The reason to be on Klaviyo rather than Mailchimp is the store data, and it is the part most accounts never touch. Klaviyo syncs order history, browsing behaviour and catalog data from Shopify natively. That makes the following possible without building anything:
→ Segment on what people bought
Product category, order count, days since last order, average order value. A second time buyer of one product is a different person to a first time buyer of another, and should not get the same email.
→ Predicted lifetime value
Klaviyo calculates predicted CLV and expected date of next order for every customer. Most accounts have never used either. Both are available as segment conditions today.
→ Dynamic product blocks
Emails that pull live product images, prices and stock from the catalog feed, so a back in stock or cross sell email builds itself instead of being hand assembled every send.
→ Revenue attribution you can check
Per flow and per campaign, against a defined attribution window. This is how you find out that the flow everyone likes earns less than the plain text one nobody wanted to ship.
Who we help
eCommerce brands
Doing $50k to $5M a month and stuck at roughly 20% of revenue from email. The gap between 20% and 35% is almost always missing flows and a list that is being sent to indiscriminately.
Abandoned checkout that recovers rather than discounts. Browse abandonment that is correctly excluded from the checkout flow. Post purchase sequences timed to delivery.
Shopify stores
Deep Shopify and Klaviyo integration: custom properties, product feeds, dynamic content blocks. The parts of the integration that take a day to set up and then work forever.
Flows that reference actual purchase history, browsing behaviour and CLV predictions rather than a first name merge tag.
D2C and subscription
Consumables and replenishment products, where email is the retention engine and the consumption cycle is the thing worth building around.
Replenishment reminders timed to when someone actually runs out. Win back sequences that treat a lapsed VIP differently to a one time sale buyer.
When you should not hire a Klaviyo agency
If your list is under about five thousand people, the constraint is list growth and not email strategy. A retainer will not pay for itself. Fix lead capture, build a welcome flow and an abandoned checkout flow yourself, and revisit this when there are enough subscribers for segmentation to mean anything.
If you are doing under roughly $20,000 a month in revenue, the same applies. Email at 30% of a small number is still a small number, and the money is better spent on whatever is bringing people to the site in the first place.
If someone in the business genuinely enjoys this work and has time for it, Klaviyo is well documented enough that they will get most of the way there. The parts that reliably need outside help are diagnosis, which means working out which of a dozen possible causes is suppressing your results, and segmentation logic, which is a judgement problem rather than a software problem.
We would rather tell you this now than take a retainer for six months and hand back a report.

Klaviyo questions we get asked
What does a Klaviyo agency actually do?+
Three things, in this order. It fixes the account so email reaches the inbox, which means a dedicated sending domain, authentication and a sending pattern Klaviyo will not throttle. It builds the flows that run without anyone touching them, which is where most of the revenue sits. Then it runs campaigns against segments rather than the full list. Agencies that skip straight to campaign design are selling you the least valuable part.
How much does a Klaviyo agency cost?+
Most retainers in this market sit between $2,000 and $8,000 a month depending on whether the agency writes the emails or just builds the mechanics. A one-off flow build is usually $4,000 to $12,000. The number that matters more is what email contributes to revenue. If email is at 15% of revenue on a $200,000 month, moving it to 30% is $30,000 a month, and any of those retainers is cheap. If you are doing $20,000 a month, a retainer will not pay for itself yet and you should do it yourself.
Do I need an agency or can I set up Klaviyo myself?+
You can build the flows yourself. Klaviyo is designed for that and the templates are decent. The parts that genuinely need experience are diagnosis and segmentation logic: working out which of a dozen possible causes is suppressing your open rates, and deciding what a segment should actually be. Building an abandoned cart flow is an afternoon. Working out why it converts at 2% instead of 8% is the hard part.
How long before Klaviyo flows make money?+
Flows start earning as soon as they are live, because they fire on traffic you already have. A welcome and abandoned cart flow built in week one usually shows revenue in the first month. Deliverability repair is slower. If your domain reputation is damaged, expect six to eight weeks of disciplined sending before inbox placement recovers, and there is no way to shortcut it.
What percentage of revenue should Klaviyo drive?+
For most eCommerce brands, 25% to 35% of total revenue attributed to email is a healthy range, with flows out-earning campaigns roughly two to one. Below 20% usually means either the flows are missing or deliverability is quietly broken. Above 40% often means the rest of the marketing is underperforming rather than the email being exceptional.
Can you fix Klaviyo deliverability problems?+
Usually, but the fix depends on the cause. Klaviyo puts new senders on shared IPs, so your placement is partly a function of the pool you are in and mostly a function of your own engagement rates. The common causes are sending to a full list that includes people who have ignored you for a year, no dedicated sending domain, or an import that should never have happened. Start with the free deliverability audit to find out which one applies before paying anyone.
Do you migrate from Mailchimp to Klaviyo?+
Yes, and the migration itself is the easy part. The risk is reputation. Moving platforms resets the sending history that inbox providers use to judge you, so a migration that dumps the full list into Klaviyo on day one often lands in spam. The right approach is to move the list, rebuild the flows, then ramp volume over three to four weeks starting with your most engaged subscribers.
Klaviyo or Mailchimp for an eCommerce store?+
Klaviyo, if you sell physical products and care about what individual customers bought. Klaviyo syncs order and browsing data from Shopify natively, so you can segment on purchase history, product category and predicted lifetime value without building anything. Mailchimp is cheaper and fine for a newsletter, but you will hit its limits the moment you want a flow that references what someone actually bought.
Do you work inside our Klaviyo account?+
Yes. We need an account seat, and Shopify or your store platform connected. We do not need admin on your DNS, though authentication changes have to be made by whoever does control it. Everything we build stays in your account and is yours if the engagement ends.
What if our list is small?+
Under about 5,000 subscribers the constraint is usually list growth, not email strategy, and a retainer is the wrong spend. Fix lead capture first, build a welcome flow and an abandoned cart flow yourself, and come back when there are enough people receiving the emails for segmentation to mean anything.
