How to choose a Klaviyo agency.
Choose a Klaviyo agency by looking for evidence of work like yours, a clear process you can describe back, and people who will actually run your account. Ask to see real flows and the reasoning behind them, and be wary of anyone who promises a revenue number before they have seen your data.
Start with proof that fits your store.
Look for examples in a similar category, with a similar order value and repurchase pattern. A beauty brand with a thirty day reorder cycle needs different flows from a furniture store that sells once every few years, and an agency that has only done one of those will bring habits that do not transfer.
Ask for the work itself, not a logo wall. A good agency can show you a flow, explain the trigger, the timing and why each email exists. If the explanation is vague, the work probably was too.
Check the process, not the pitch.
A reliable agency can describe what happens in the first two weeks, who you speak to, how approvals work and how changes are tested. You should be able to repeat that process back to a colleague after one call.
Ask how they decide what to build first. The honest answer is usually an audit of what exists, ranked by likely impact, rather than a fixed package of twelve flows.
Meet the people who will do the work.
Many agencies sell with senior people and hand the account to someone junior. That is not always bad, but you should know who will build your emails, who will review them and who you can escalate to.
Ask what happens if your account manager leaves. A good answer involves documentation and a second person who already knows your account.
Look at how they talk about results.
Results depend on your product, your list and your offer, so an agency that guarantees a number before an audit is guessing. Prefer an agency that explains what they will measure, how they will separate email revenue from sales that would have happened anyway, and when you will see the first read.
In practice.
Picture a skincare brand with a thirty day reorder cycle choosing between two agencies. One shows a polished deck and a revenue promise. The other opens a live flow, explains why the replenishment email goes out on day twenty five, and asks about margins on refills. The second agency has done the thinking that matters, even if the deck is plainer.

- Skipping a conversation about account ownership and access
Questions people ask.
How many agencies should I speak to?
Two or three is enough. More than that tends to blur the differences, and the useful comparison is how each one reasons about your account.
Should I choose a Klaviyo specialist or a general agency?
A specialist usually knows the platform and the ecommerce patterns better. A general agency can work if email is a real discipline in their team and not a side service.
Do I need to see results from other clients?
Seeing real work and hearing the reasoning is more useful than a results table, because results depend on the store. Ask how they would adapt the approach to yours.
