Quick answer: The best Klaviyo agency for you is the one that can show revenue results in accounts like yours, tells you exactly what happens in the first month, prices a fixed scope in the open and protects your data. Use the questions below to test any agency, including Excelohunt. At Excelohunt, managed plans start at $499 a month and fixed-price Klaviyo projects start at $209, all listed on Excelohunt’s pricing page.
Key takeaways
- Proof beats promises: ask for case studies with real before and after numbers, not logos.
- The first month tells you everything: a good agency can describe it day by day.
- Fixed scope, published prices: you should know what you get before you sign.
- Your account, your data: read-only access to start, an NDA if you want one, and access you can remove any time.
- Fit matters: some brands need a full team, others need one flow built well. Both are valid.
Searching for the best Klaviyo agency usually turns up long lists that rank agencies without telling you how to judge one. This guide does the opposite. It gives you the checks worth running on any agency, shows how Excelohunt answers each one, and lets you hold every agency to the same standard.
What the best Klaviyo agencies have in common
The strongest Klaviyo agencies share six traits, and every one of them can be checked before you sign.
- They start with an audit, not a pitch. Before recommending anything, a good agency looks at your deliverability, your flows and your list health. For example, Excelohunt’s free audit uses read-only access and benchmarks your open, click and conversion numbers against your category.
- They fix the foundations first. Authentication, list hygiene and sending reputation decide whether anything else works. In Excelohunt’s Crossfly case study, the deliverability score went from 19 to 96 before email grew to a peak of 66% of store revenue.
- They build flows that earn while you sleep. Welcome, abandoned cart, browse abandonment, post-purchase and win-back flows do the steady work. A strong agency reviews them regularly; Excelohunt goes through live flows at least every two weeks.
- They plan campaigns as a calendar. Every send has a purpose and an audience, decided in a monthly strategy rather than email by email.
- They report revenue, not vanity metrics. Attributed revenue, flow performance and deliverability health, every month, with the reasoning behind next month’s plan.
- They are clear about scope and price. You know what is included, what is not, and what it costs.
The questions to ask before you sign
Ask every agency these seven questions, and listen for specifics. Vague answers are the most reliable warning sign you will get.
| Question | What a strong answer sounds like | How Excelohunt answers it |
|---|---|---|
| What happens in the first month? | A dated plan with deliverables | Strategy by day 3, calendar and first design by day 7, campaigns live from week 2, flow findings in week 3 |
| Can I see results from a similar brand? | Named case studies with real numbers | Six published case studies, for example email and SMS moving from about 12% to 81% of store revenue in one season |
| How often do you review my flows? | A set rhythm and what gets checked | At least every two weeks: performance, targeting, trigger and split logic |
| What exactly is included in the price? | A written scope | Strategy, calendar, copy, custom design, segmentation and a monthly report on every plan |
| How do you handle my data? | Read-only access, named people, no exports | NDA on request, read-only analyst access, MFA, no exports without written approval |
| What happens if results lag? | Clear targets and a review point | Short-term targets such as deliverability and click rate while the bigger changes roll out |
| Can I leave? | Month to month | Month to month, with no long-term lock-in |
Red flags to watch for
- A guaranteed revenue number before anyone has looked at your account. Email results depend on traffic, offers and seasonality too. A responsible agency sets targets after an audit.
- No access to your own data. You should always own the Klaviyo account and be able to remove the agency’s access.
- Hourly billing with no defined output. Fixed scope keeps everyone focused on results rather than the clock.
- Templates presented as strategy. Pretty emails without segmentation, timing and testing rarely move revenue.
- No reporting rhythm. If you cannot say when you will next see numbers, you will not see them often enough.
What a Klaviyo agency should cost
Klaviyo agency pricing depends on scope: how many campaigns, how many flows and how much strategy you need. Here is what Excelohunt charges, so you have a real reference point. Excelohunt’s full Klaviyo agency pricing guide explains how the models work.
| What you need | Excelohunt price |
|---|---|
| One flow built properly | From $209 (birthday flow) to $419 (welcome series); abandoned cart is $349 |
| Your core flows at once | Core 5 Flows Bundle, $1,399 |
| A full account setup | Email Platform Setup, $559 |
| Managed campaigns | $499 a month (2 campaigns) to $2,999 a month (20+ campaigns) |
| Custom or multi-market work | Quoted after a free audit |
Excelohunt’s fixed-price projects are bought online in its shop without a sales call. Its managed plans are month to month, and brands the Excelohunt team confirms as eligible are covered by its 3x ROI guarantee: at least a 3x return on investment within six months, or Excelohunt keeps working at no extra cost.
What the first month should look like
A good agency can describe month one in detail, because it has done it many times. Here is Excelohunt’s:
- By day 3: the strategy, built from the audit and your goals.
- By day 7: the content calendar and the first email design for your approval.
- From week 2: campaigns go live.
- Week 3: findings on your existing flows, with the fixes Excelohunt recommends.
- End of the month: a monthly report and a strategy meeting that sets the next month.
One automated flow takes about three days end to end, covering copy, design and testing. Excelohunt agrees the designs with you before building them in Klaviyo, which avoids rework later.
What results look like
Every brand starts from a different place, so look for proof that matches your situation:
- Deliverability problems: Crossfly went from a deliverability score of 19 to 96, then grew email to a peak of 66% of store revenue through a four-market migration.
- Email underperforming next to social: 8 Other Reasons took email and SMS from about 12% to 81% of store revenue in one season.
- A dormant account: Unique Party Shop turned an unused Klaviyo account into 14% of store revenue.
- Reporting you cannot trust: for a US fragrance retailer, Excelohunt fixed the attribution setting that hid what email was doing and lifted open rates from 45% to 59%.
When an agency is not the right answer yet
Not every brand needs a retainer. If you only need one piece of work, a fixed-price project from Excelohunt’s shop may be enough. If you want someone working inside your team, you can hire a vetted Klaviyo expert instead. And if you are deciding between building a team and hiring help, Excelohunt’s guide to in-house vs agency email marketing walks through the trade-offs.
Frequently asked questions
How do I choose the best Klaviyo agency?
Judge the agency on four things: proof of revenue results in accounts like yours, a clear plan for the first month, transparent pricing with a fixed scope, and how it handles your data and access. Ask for case studies with real numbers and for a written first-month timeline before you sign.
How much does a Klaviyo agency cost?
At Excelohunt, fully managed campaign plans run from $499 a month for 2 campaigns to $2,999 a month for 20 or more, and fixed-price Klaviyo projects start from $209 (an abandoned cart flow is $349). Custom builds are quoted after a free audit.
What should a Klaviyo agency deliver in the first month?
Expect a strategy within the first few days, a content calendar and first designs within the first week, campaigns going live from week two and a review of your existing flows soon after. At Excelohunt that is day 3, day 7, week 2 and week 3, followed by a monthly report and strategy meeting.
Should a Klaviyo agency guarantee results?
Be careful with fixed revenue promises, because results depend on traffic, offers and the market as well as email. Excelohunt offers a 3x ROI guarantee only to brands its team confirms as eligible on the free audit, and commits to disciplined execution against clear targets.
Do I keep control of my Klaviyo account?
You should. A good agency works inside your account with access you can remove at any time, and your data never leaves your platform without written approval. Excelohunt is also happy to sign an NDA before getting access.
