Paying for Klaviyo but Not Using It? Start With Flows, Not Newsletters

You are paying a small fortune for Klaviyo every month. You log in, see a dashboard you do not really understand, and log back out. Maybe you have an abandoned cart email running. Maybe a post-purchase note. And that is it.

If that is you, take a breath. You are not behind. Your email just has not had a specialist on it yet, and the fix is more straightforward than the guilt is making it feel.

Here is the thing most founders get told to do, and it is the exact wrong first move: start blasting newsletters. Before you send a single campaign, there is a better place to begin. This is where.

Quick answer: should I set up Klaviyo flows or newsletters first?

Set up your Klaviyo flows first. Flows are the automated emails that trigger off what a shopper does on your site, like a welcome sequence, abandoned cart, browse abandonment and a thank you. They run in the background and make money without you touching them. Newsletters come after the foundations are built, because flows are what capture and convert the traffic your newsletters send. Foundations first, newsletters second.

What is the difference between a Klaviyo flow and a newsletter?

Let me translate the jargon, because this trips up nearly everyone.

A flow is an automated email (or series of emails) that Klaviyo, the email and SMS platform built for ecommerce, sends on its own when someone does something. Someone signs up, they get your welcome flow. Someone leaves a full cart, they get an abandoned cart email a little while later. You build it once, and it keeps sending forever.

A newsletter (Klaviyo calls it a campaign) is a one-off email you write and send to a list at a set time. A new arrivals email. A sale announcement. A story about the maker behind your product.

The simplest way to hold it in your head: flows react to individual behaviour, newsletters go out to everyone at once. Flows are the engine. Newsletters are the fuel you pour in later.

Why should I build my flows before sending newsletters?

Because flows amplify everything that already happens on your website. They need traffic fed to them to generate sales, and right now that traffic is walking in, browsing, half-filling a cart, and leaving with nothing to bring them back.

Picture your welcome flow as a proper front-of-house team. When you finally do send a newsletter, or run an ad, or get a burst of organic traffic, all those new people land on your site. Without flows, the ones who do not buy on the spot just disappear. With flows in place, they get caught: a welcome sequence that introduces your brand, an abandoned cart that nudges the ones who hesitated, a browse abandonment for the window shoppers.

Send newsletters to a cold list with no flows behind them and you are pouring water into a bucket full of holes. Build the flows first and the same traffic is worth far more, because now there is something catching the people who were always going to slip away.

Newsletters bring people to the party. Flows are what stop them leaving before they buy.

Where do I actually start with Klaviyo?

You do not need everything at once. Going too big too soon is a classic mistake, especially if you are not emailing regularly yet. A giant set of flows will just sit there half-used. Start with the foundations that earn their keep from day one.

Here is the order I recommend for a product brand starting close to scratch:

• Sending domain first. Before anything else, authenticate your sending domain. This proves to inboxes that the email really comes from you, so you land in the inbox instead of spam. Skip it and everything else is wasted effort.
• A welcome flow. Your highest-earning automation, nearly every time. It greets new subscribers, tells your story and turns a fresh sign-up into a first-time buyer.
• Abandoned cart and browse abandonment. The two flows that quietly recover sales you would otherwise lose. One catches the people who added to cart and left, the other the people who looked and did not add.
• A win-back flow. For past customers who have gone quiet, gently pulling them back before they forget you exist.
• A thank you flow. Especially if you sell to women or in a sensitive category, this is the one that builds the emotional connection. Not a hard sell. Just a genuine, kind note that says you are more than an order number.

Once those are live and feeding off your traffic, then you layer newsletters on top. And here is the nice part: newsletters feed back into the flows too. Every campaign you send drives more clicks and more site activity, which triggers more flow emails, which makes more sales. The two work together once the foundation is there.

How many subscribers do I actually have (and why am I paying for all of them)?

This one surprises almost everyone, so it is worth spelling out.

The number Klaviyo shows you under active profiles is not the same as your subscriber count. An active profile is anyone Klaviyo is tracking, including people who bought once and never opted in to your marketing. You pay for all of them, whether or not they are subscribers.

That is not automatically a bad thing. Klaviyo keeps a non-subscriber’s data, so if they come back and abandon a cart, your abandoned cart flow can still reach them and recover the sale. You cannot send them newsletters, but the behavioural flows still work. For a product people buy once every year or two, keeping that data is often worth the spend.

Where it gets expensive is when you are paying for a big list of people who are neither subscribed nor active. The move is to create a segment of true subscribers so you can see your real number, then decide honestly: is it worth keeping the rest, or is it time to clean house and cut the bill? There is no shame in either answer. It just needs to be a decision, not an accident.

What happens when I start emailing a list that has gone cold?

Brace for a spike in unsubscribes and a few spam complaints on your first few sends. This is completely normal and, honestly, a good thing.

Those people have not heard from you in ages. Some barely remember signing up. When you start showing up in their inbox again, the ones who are not interested will leave. Let them. You do not want to keep paying to email people who will never buy, and their disinterest drags down your deliverability for everyone else.

A smaller, engaged list beats a big, sleepy one every single time. The early clean-out is not a failure. It is the list sorting itself into the people who actually want to hear from you.

Key takeaways

• Build your Klaviyo flows before you send newsletters. Flows are the engine that converts the traffic newsletters and ads send.
• Authenticate your sending domain first, or everything else lands in spam.
• Start with the foundations: welcome, abandoned cart, browse abandonment, win-back and a thank you flow. Do not over-build too soon.
• Active profiles are not the same as subscribers. Check your real subscriber number so you are not overpaying.
• Expect a spike in unsubscribes when you first email a cold list. That is the list cleaning itself, and it is a good thing.
