When it comes to the best email marketing software, Kit and Klaviyo are two names you’ll hear again and again. They help you promote your brand in the inbox and sell more products.

I’ve used Kit for my own campaigns and tested Klaviyo for this article, and it quickly became clear that while they help you achieve the same goal, they’re built for very different users.

And if neither feels like the right fit, you’re likely to feel right at home with beehiiv.

In this Kit vs Klaviyo vs beehiiv comparison, I’ve pulled together my hands-on experience and research into a clear, side-by-side breakdown to help you choose your best match.

Why Trust Me?

Kawusara has 5 years of experience using email marketing tools to run her side projects. This allows her to write comprehensively about the topic and share her unique insights.

beehiiv’s clean, intuitive interface makes it easy to get started without much guidance. New users get a quick onboarding tour, and from there, you can start drafting your first newsletter almost instantly. 

All core features—writing tools, growth, earnings, and analytics—are neatly organized in a collapsible left-hand panel for simple navigation. 

While Kit’s interface isn’t as sleek as beehiiv’s, it’s just as straightforward to use. 

I was able to find my way around and explore most features without much hassle—or needing to dig through the help center. If ease of use is a top priority, both beehiiv and Kit will serve you well.

Klaviyo’s interface looks busy and a little intimidating at first. But after spending some time with it, you’ll find that it’s easier to use than it appears. 

Still, its wide range of features means there’s a learning curve. It’s designed for experienced marketers who are willing to invest the time to use it to its full potential.

Kit offers 23 email templates to start with, all fully customizable in a block editor that works a lot like Google Docs (with a touch of Notion).

If you’re a non-techie person who likes to focus on your writing instead of fussing about design, you’ll love this setup. Besides text, Kit’s editor lets you add images, audio, video, file attachments, countdown timers, and polls to your emails.

When you’re done writing your content, you can publish it to the web, your subscribers’ inboxes, or both.

While beehiiv has fewer templates (seven in total), the writing experience feels similar to Kit’s. You can use slash commands to add content blocks and access the same publishing options.

What makes beehiiv stand out is its built-in AI tools for drafting content, editing, and generating images, plus the option to invite team members to collaborate on emails. 

Klaviyo comes with over 300 email templates, most of them highly visual and perfect for showcasing products.

You’ll find templates for product launches, new arrivals, and holiday sales, with filters to help you find what you need quickly.

Kit and beehiiv have mobile-friendly templates by default, but Klaviyo takes it further. You can choose which content blocks show on desktop, mobile, or both, and even use conditional logic to display content based on a subscriber’s location, gender, items in abandoned cart, and more.

For E-commerce brands, this level of control is very helpful for creating personalized campaigns at scale.

beehiiv lets you organize subscribers with tags (aka labels). For instance, you might tag people as “2025 Webinar Attendee” if they joined your webinar, or label them “Weekly Newsletter” or “Monthly Newsletter” based on their preferences from polls or surveys.

You can group multiple tags into a segment or create new subscriber segments based on details like their location, acquisition source, open rate, or click rate.

When you have these set up, it’s so much easier to send the right content to the right people at the right time.

Kit’s tagging and segmentation work much like beehiiv’s, but with additional targeting options. 

You can tag and segment subscribers based on the specific signup form they used to join your email list (yhup, unlike beehiiv, you can create multiple signup forms inside Kit) or on specific links they clicked in your emails.

Klaviyo takes segmentation to a whole new level. It does everything Kit and beehiiv can, and much more.

Firstly, since Klaviyo supports both email and SMS marketing, you can build segments based on subscribers’ engagement levels in either channel. 

Plus, Klaviyo integrates seamlessly with top ecommerce platforms like Shopify, WooCommerce, and BigCommerce. This means you can target subscribers based on their activity on these platforms—like viewing a product, adding items to cart, and completing a purchase.

These features may be overkill for digital solopreneurs, but they’re a goldmine for E-commerce brands and enterprise marketers looking to boost conversions and encourage repeat purchases.

Besides sending your regular newsletters, you sometimes need to set up automated email sequences that welcome new subscribers or encourage them to take a specific action—whether that’s attending an event or purchasing a product or service.

beehiiv’s visual automation builder makes this easy. You can combine triggers, conditions, and actions to create flows that fit your goals.

You don’t have to build your automations entirely from scratch in Kit. It comes with 25 prebuilt templates for use cases like raising funds for a project, launching a new podcast, and promoting a digital product.

You can customize an automation flow with up to five triggers and set rules so subscribers can exit a flow if they take certain actions. For example, if you’re promoting an ebook, Kit can automatically stop sending promo emails to anyone who’s already purchased it.

While Klaviyo’s templates are fewer than Kit’s, the builder itself is far more advanced.

For instance, you can create email and SMS flows in one place and run A/B tests directly inside the automation builder to see which paths lead to more opens, clicks, and conversions.

Klaviyo gives you basic list-building tools like signup forms you can embed on your website, landing pages, or E-commerce store to collect subscribers and grow your email list. 

And…that’s about it. 

You’ll need to handle the traffic side yourself to get people to those forms.

Kit goes a step further. Along with signup forms, it has a built-in recommendation network, which is a more passive way to help your list grow. 

Once you join, you can find other creators in your niche, recommend them to your audience, and have them recommend you in return.

Meanwhile, beehiiv packs in the same tools as Klaviyo and Kit, plus a couple of extra growth features. 

There’s a referral program that rewards your current subscribers for bringing in new ones, and a Boosts feature that lets you pay other beehiiv creators to promote your newsletter to their audience.

Klaviyo doesn’t support earning directly from the platform. Its focus is on helping you promote your brand and products so you can drive sales through your own business.

beehiiv, on the other hand, has built-in tools to help you make money directly from your emails. You can:

Whatever you earn is yours to keep. You’ll only have to pay Stripe processing fees.

Kit wasn’t originally built for earning, but it now offers similar features to beehiiv—ads, paid recommendations, and paid newsletters.

However, they come with strict requirements. For instance, to join Kit’s sponsor network and place ads in your emails, you’ll need at least 10,000 subscribers and send at least one newsletter every week. Kit also takes a 20% cut of your ad earnings (plus Stripe fees).

On the plus side, you can host and sell digital products directly on Kit, so you don’t have to pay for third-party tools.

Kit’s analytics covers the basics. It lets you track open rates, click rates, and unsubscribes across all your emails. You can also track the conversion rates of your signup forms and landing pages. 

Recently, Kit launched an Insights dashboard for getting in-depth insights into your subscriber acquisition, engagement levels, and digital sales performance. However, this feature is only available on Kit’s highest paid plan.

Meanwhile, beehiiv’s analytics dashboard is split into two main pages: 

Klaviyo’s analytics are the most thorough, especially when it’s connected to your ecommerce shop. 

It lets you track how your email and SMS campaigns affect metrics like placed orders, total revenue, and revenue per recipient.

You can even benchmark these metrics against industry peers to spot opportunities for improvement.
