5 Reasons We Love Klaviyo

Written By Jackie Dean

There are over 400 email marketing platforms. Of those 400, there are about 15 front-runners.

We’ve used them.
We’ve tested them.
We’ve found the best and have migrated clients off the rest.

If you don’t know, now you know. The number one platform is Klaviyo “clay-vee-oh” > watch this video for how to properly pronounce it

Platforms like Constant Contact, Mailchimp, and HubSpot absolutely have their place, especially when you’re just getting started. But as brands grow, goals grow, and marketing efforts need to actually drive revenue, leads, and onsite visits, this is when the gaps start to show.

That’s where Klaviyo comes in.

Before we dive in, let’s give credit where credit is due. And then we’ll get into why Klaviyo is the platform we love, use daily, and confidently recommend for all brands serious about growth.


The Other Guys (And Where They Fall Short)

Constant Contact: Easy, Friendly, Limited

Constant Contact is great if you’re new to email marketing. It’s intuitive, simple to use, and doesn’t overwhelm you with data.

Where it falls short:

  • Very limited customer behavior tracking

  • Minimal segmentation capabilities

  • Little to no revenue attribution

  • If you’re sending general information out, it’s fine. If you’re trying to understand your audience/customer’s behaviors, looking to gain repeat customers, or create a more personalized strategy, you’ll outgrow it fast.


Mailchimp: Familiar, Flexible… Until It Isn’t

Mailchimp is often the first email tool people use, and for good reason. It’s affordable, widely known, and works well for basic campaigns.

Where it falls short:

  • Advanced segmentation gets clunky quickly

  • Reporting focuses on engagement, not revenue

  • Automation depth is limited

Mailchimp is solid for just sending emails. But if you’re focused on driving sales, crafting personalized messaging, and deeply understanding your customers, it’s time for a more strategic solution.


HubSpot: Powerful, Enterprise-Level, Overkill for E-commerce

HubSpot is definitely loaded—with CRM, sales tools, marketing automation, and an entire ecosystem built to work together.

Where it falls short:

  • Expensive as you scale

  • Email and e-commerce analytics aren’t deep or intuitive

  • Very limited on design

HubSpot shines for complex B2B funnels. But if your priorities lean more toward purchases, brand consistency, and repeat customers, you’ll want to look beyond it.


So, why Klaviyo?

Here are five reasons why we keep coming back to Klaviyo. Honestly, we have more, but we didn’t want you to have to read a full-on love novel.

1. Customer Insights & Marketing Analytics

Klaviyo doesn’t just tell you who your audience is; it tells you how they behave, both online and over time.

With Klaviyo, you can see:

  • What customers purchase and how often

  • What your audience is interested in to better create segmentation for it (see #2 for more on this)

  • Average time between purchases

  • Which products naturally pair together for cross-sells

  • When a customer evolves from “good” → “great” → “kick-ass”

Instead of guessing, Klaviyo lets you market based on actual behavior.

2. List Segmentation (AKA: The Real Power Move)

This is where Klaviyo becomes incredibly powerful for both e-commerce and brand email marketing. Segmentation is where Klaviyo absolutely dominates.

With Klaviyo, you can:

  • Use pre-built segments or build your own from scratch

  • Customize metrics based on your business goals

  • Segment by behavior, spend, frequency, products viewed, and more

  • Create a preferences landing page inKlaviyo and push your audience to update their preferences (creating a more personalized strategy, to give them exactly what they want… AKA less likely to unsubscribe)

The result? More relevant emails, higher engagement, and more people actually showing up. Klaviyo understands and gives you the flexibility to create segments that actually make sense. No one-size-fits-all lists.

3. Dashboard, Analytics & Reporting

Whether you're driving online sales, sending personalized messaging, or targeting specific audiences, Klaviyo shows you what’s working. Opens and clicks on data points are expected. Klaviyo goes way beyond that.

With Klaviyo, you can:

  • See exactly how much revenue an email or flow generated

  • Track conversions at a granular level

  • Customize attribution windows

Seeing “This email generated $4,200” hits a little differently than “Your open rate was 32%.”

4. Catalog Insights

For e-commerce brands, this is where Klaviyo becomes a revenue-driving machine.

Klaviyo analyzes:

  • Items purchased together

  • Repeat purchase timing

  • Product affinity and trends

Then it hands you the playbook. Think of it as the heavyweight champion showing you exactly how to take on André the Giant.

5. Klaviyo Academy

Don’t know how to do something? Klaviyo’s already thought of that.

Klaviyo Academy offers:

  • Step-by-step videos

  • Blogs and tutorials

  • Strategy guidance for beginners and pros

Whether you’re learning the basics or optimizing advanced flows, the education is there… and it’s actually useful.

Klaviyo Suggested Marketing Strategies

Feeling Hesitant? Totally Understandable.

We get it. Migrating to a new email platform can feel intimidating. There are so many factors that go into play, we’ve heard:

  • “Klaviyo is more expensive.”

  • “Our lists are messy.”

  • “We don’t want to lose our data.”

  • “We don’t have time to rebuild everything.”

And those concerns are valid.

Klaviyo is a much more powerful tool than most platforms, which means it does require a more thoughtful setup and investment. If your goals are limited to general newsletters to a wide audience, Klaviyo might be too much for what you need.

But, if you’re looking to increase your brand’s ability to hypertarget your audience, drive more online revenue, turn data into strategy, understand your audience better, and automate your brand without losing the human touch, then there’s no other place like Klaviyo.


This Is When You Need A Strategic Partner ( 🤜⚡️🤛 )

This is exactly where the right partner and the right strategy make all the difference.

At Dean&Co., we’re honest about fit.

If your goals don’t require Klaviyo’s level of segmentation, automation, and analytics, we’ll tell you. There are plenty of platforms that are more than sufficient for simpler needs, and we’re not here to oversell technology.

But if your goals include:

  • Driving measurable revenue or conversions

  • Increasing onsite traffic and tenant engagement

  • Segmenting audiences by behavior and interest

  • Understanding what content actually moves people to act

Then Klaviyo becomes an investment, not just a tool.

We can help:

  • Set up the platform

  • Clean and organize existing lists

  • Preserve historical data and subscriber integrity

  • Build smart segmentation from day one

  • Build automations to welcome, keep, and re-engage your audience

  • Set up reporting that ties marketing efforts to real outcomes

  • Create email strategies that support long-term growth

No guesswork. No panic. No paying for tools you don’t use.

Just a smarter system with a collaborative, honest, and realistic partner.

In A Nutshell

Whether you're selling products or promoting your retail center, the goal is the same: get the right message in front of the right people and drive action. Constant Contact, Mailchimp, and HubSpot all serve a purpose. But when it comes to ecommerce-driven growth, customer behavior, and revenue-focused marketing, Klaviyo is in a league of its own.

It’s not just an email platform, it’s a customer intelligence engine.

And that’s why we love it.
