2. Features and Functionality



Klaviyo offers powerful automation through Floows, its visual workflow builder. You can create complex triggers and multi-step campaigns with conditional logic, custom metrics, and dynamic audience segmentation. For example, you can send behavior-based abandoned cart emails or customize journeys based on customer lifetime value.

Key automation features include welcome campaigns, flows, metrics, SMS, and platform integrations like email, webhooks, and Zapier. Klaviyo also offers dedicated tools for WooCommerce, Shopify, and BigCommerce. Everything is optimized for mobile apps as well.

Overall, Klaviyo provides extremely robust and customizable automation for e-commerce stores and SaaS companies. You can truly customize things to match your business needs.

Campaign Monitor

Campaign Monitor has its Automation Studio for creating triggered campaigns and sending automated emails. You can build customer journeys with basic if/then logic and timing-based triggers. For example, send a follow-up email 5 days after a customer downloads an ebook.

The platform supports welcome series, lifecycle campaigns, behavioral targeting, and integration with many popular e-commerce platforms. However, its automation capabilities are not quite as advanced compared to Klaviyo Flows. There is less flexibility for custom metrics and complex multi-channel flows.

That said, Campaign Monitor automation will still meet the needs of most small business use cases. It provides solid prebuilt templates and an easy drag-and-drop workflow builder.

Winner: Klaviyo

Klaviyo is the winner for best email marketing automation due to its remarkably robust and customizable feature set enabling highly advanced e-commerce journeys. Floows workflows provide unmatched flexibility tailored to data-driven brands.

Email Templates


Klaviyo offers hundreds of professionally designed, customizable email templates for welcome series, promotions, announcements, newsletters, and more. Templates are mobile-optimized and you can preview them across different devices.

There are specific templates optimized for important e-commerce scenarios like abandoned carts, product launches, shipping updates, back-in-stock alerts, and personalized recommendations. All templates can be edited using the drag-and-drop editor.

While Klaviyo provides templates for every major email campaign type, advanced users have the flexibility to build custom HTML templates from scratch. You can also create Master Templates to manage global styling.

Overall, Klaviyo strikes a great balance between plug-and-play templates for quickly getting started while also offering customization capabilities to more advanced users.

Campaign Monitor

With over 600 mobile-ready email templates, Campaign Monitor is marketed as a leading email template provider. There are templates optimized for every major industry and campaign objective – promotions, newsletters, announcements, onboarding campaigns, and more.

While they provide basic e-commerce templates, Campaign Monitor’s strength lies more in traditional email marketing scenarios compared to specialized e-commerce sequences. But the drag-and-drop editor does make it easy to customize any template to match your brand.

Developers can also leverage the Android mobile app, as well as the Template Language to build custom email templates with dynamic content pulled from your website or database. There are also tools to manage global header, footer, and style changes.

Winner: Tie

Both Klaviyo and Campaign Monitor offer excellent curated galleries of professional email templates as well as customization capabilities to tailor emails to your brand. For most small business use cases, the out-of-the-box templates will suffice so this category results in a tie. However, Klaviyo provides more advanced ecommerce-specific templates.



Klaviyo offers powerful segmentation tools to divide your customer database into highly targeted lists and subgroups. You can create segments based on detailed behavioral data, custom metrics, transaction history, lifetime value, product attributes, and more. Klaviyo automatically updates segments as your customers meet new criteria.

For example, easily segment customers by location, frequency of purchase, average order value, which links they clicked in your last email, how many times they’ve opened an email, days since their last visit to your site, whether they downloaded a file, and much more. You can also integrate Klaviyo with analytics tools like Google Analytics for even deeper insights.

With Klaviyo’s granular data and custom metrics, the segmentation possibilities are truly endless, enabling hyper-personalized messaging and promotions.

Campaign Monitor

Campaign Monitor enables you to segment your subscribers by location, email activity, links clicked, date subscribed, and basic purchase history so you can send timely transactional emails. It leverages data from your email campaigns as well as integrations with e-commerce platforms to update segments automatically.

However, without the ability to build segments based on more advanced omnichannel criteria and custom metrics, Campaign Monitor trails Klaviyo when it comes to detailed subscriber segmentation. But Campaign Monitor still provides enough basic segmentation capabilities for typical small business needs.

Winner: Klaviyo

With its unparalleled ability to track detailed customer behavior across channels and leverage custom metrics for segmentation, Klaviyo is the clear winner. Granular data combined with easy segment-building tools enable incredibly personalized, targeted messaging not possible in Campaign Monitor.



Klaviyo enables deep analytics across your email campaigns and website with its metrics product. You get insights on email sends, delivery, open rates, clicks, bounce rates, uninstalls, spam complaints, and more. Metrics integrate revenue and order data to track ROI across acquisition channels.

You can view real-time dashboard reports on revenue, conversions, customer lifetime value, and subscriber engagement rates. Klaviyo also provides analysis on website traffic, popular site pages, landing pages, and UTM tagging. Everything syncs with your ecommerce platform. Advanced users can leverage the API and custom metrics for further analysis.

Overall, Klaviyo shines when it comes to detailed analytics and reporting to optimize your sales funnels.

Campaign Monitor

Campaign Monitor offers email campaign reporting on opens, clicks, bounces, unsubscribes, spam complaints, and more. You can view delivery and engagement rates over time to spot trends. It also integrates e-commerce data for basic ROI tracking based on purchases driven by each campaign.

However, Campaign Monitor lacks more advanced behavioral analytics and the ability to track website analytics in one unified interface. You would need to complement it with a dedicated analytics platform like Google Analytics for website traffic data and advanced insights.

Winner: Klaviyo

With its unified dashboard tracking every aspect of email and website performance plus the ability to incorporate custom metrics, Klaviyo wins when it comes to actionable analytics. It provides unmatched end-to-end visibility into your marketing funnel and subscriber engagement.

Unique Features


A few unique benefits Klaviyo provides are advanced SMS marketing, dynamic forms and surveys, and its Reclaim tool.

Klaviyo’s SMS platform seamlessly integrates with your email and website data for unified messaging. You can build SMS workflows just like email automation.

Dynamic forms leverage customer data to customize signup, checkout, and survey forms on your website on a per-visitor basis. Reclaim helps you win back lost subscribers by rebuilding suppressed contact lists and reactivating inactive email addresses.

These specialized tools demonstrate Klaviyo’s commitment to offering a truly unified platform encompassing every channel to maximize customer data.

Campaign Monitor

Some of Campaign Monitor’s notable unique features include multi-language support and AB testing.

Campaign Monitor makes it easy to set up multi-language campaigns reaching subscribers in their native language. You can translate email content while optimizing for regional compliance needs. Their visual email designer also enables easy A/B testing so you can experiment with subject lines, content, and design to boost engagement.

While these capabilities demonstrate Campaign Monitor’s email-first focus, they do not expand capabilities across channels like Klaviyo’s unique tools.

Winner: Klaviyo

Klaviyo wins when it comes to unique innovations that unlock more ways to leverage customer data across channels. From SMS to surveys to web forms, Klaviyo focuses on unifying data for superior personalization and automation. These specialized tools expand your marketing capabilities beyond basic email.

3. Ease of Use


Klaviyo is praised for its intuitive interface and ease of use right from the onboarding process. The dashboard neatly organizes your data and tools using simple, clean tabs like Email, SMS, Flows, Metrics, and Platform Apps.

Despite offering a deep set of capabilities, Klaviyo’s UI remains visually appealing and user-friendly. Core features for building emails, automation, and segments are designed to get beginners up and running quickly with little friction.

While there may be a learning curve to leverage Klaviyo’s more advanced tools, the platform scales well for users of any skill level. Detailed onboarding checklists and documentation also help smooth the adoption process.

Campaign Monitor

The Campaign Monitor dashboard focuses mainly on campaign creation, design templates, and reporting. The visual drag-and-drop builder makes it simple for beginners to quickly customize professional templates and launch email campaigns with no coding required.

However, those wanting to implement more complex triggered automation, customize metrics, sync integrations, and leverage API access may find Campaign Monitor less intuitive. It prioritizes simplicity over advanced customization in its interface.

The platform is very intuitive for basic email sending but lacks breadth across channels. The user experience remains streamlined as you scale usage over time.

Winner: Klaviyo

While both platforms aim to provide an intuitive first-use experience, Klaviyo’s superior transparency and organization of robust data tools give it the advantage for usability. The UI scales exceptionally well from beginner to advanced power user. Novice users also become experts faster with Klaviyo’s interlinked onboarding.

4. Email Deliverability


Klaviyo prioritizes deliverability through advanced email infrastructure and strict compliance adherence. They achieve industry-leading inbox placement rates of over 99% across ISPs.

Features like predictive email intelligence, adaptive delivery technology, and dynamic content optimization help avoid spam filters. Granular analytics offer visibility into email reputation factors.

For example, Klaviyo adaptive delivery uses algorithmic monitoring of bounce rates, spam complaints, and engagement metrics to determine optimal send times on a per-subscriber basis. This optimizes delivery for each person.

Campaign Monitor

Campaign Monitor highlights its email deliverability as its core strength. Through dedicated IP addresses and automatic spam testing, they maintain excellent global deliverability rates around 98-99% on average.

Email previews detect potential issues before sending. Campaign Monitor also provides deliverability consulting services to implement best practices around list building, content personalization, and compliance needs in your niche.

While core deliverability capabilities are strong on both platforms, Klaviyo’s advanced personalized optimization gives it an edge. But most typical use cases will achieve great inbox placement with either tool.

Winner: Klaviyo

Thanks to features like predictive email intelligence and adaptive send-time algorithms, Klaviyo wins through its uniquely optimized approach to personalized email deliverability for each subscriber. Both are great options though.

5. Customer Support and Community


Klaviyo offers 24/7 email support, live chat, phone support, and an online knowledge base resource hub to help users. You can also get 1-on-1 onboarding and integration assistance. Paid plans include a dedicated account representative.

As an engaged, growing community, the official Klaviyo Facebook group shares tips and best practices with over 20K members. Klaviyo also hosts frequent complimentary masterclasses and an annual conference called Klaviyo: Reunite.

Campaign Monitor

Campaign Monitor provides 24/5 support over live chat and email. There are also community forums to exchange ideas as well as an online knowledge base with tutorials. Phone support requires upgraded paid plans.

Users can join the Campaign Monitor Community Facebook group of over 13,000 members to discuss email marketing strategies and share inspiration. The community is active in sharing templates, tips, and workshops.

Winner: Tie

Both platforms offer excellent customer support through a variety of convenient channels complemented by engaged user communities. The breadth of self-service content and direct assistance is strong in both Klaviyo and Campaign Monitor. For most use cases, users should have no problem finding solutions.

6. Integrations


Klaviyo integrates with all major e-commerce platforms like Shopify, Magento, and WooCommerce. It also connects with top marketing and analytics tools through Zapier and native app integrations.

For example, natively integrate platforms like Google Analytics, Facebook Ads, Segment, Slack, Zendesk, and 1,000+ more. Or leverage Zapier to connect virtually any web app.

Klaviyo’s commitment to openness via API access also enables developers to build custom connections on top of the robust default offerings.

Campaign Monitor

Campaign Monitor easily integrates with popular email services, CRMs, e-commerce stores, and marketing platforms. Sync Campaign Monitor with solutions like Mailchimp, Zoho, ActiveCampaign, Shopify, and Marketo.

However, Klaviyo still supports 2X more apps natively while also offering more flexibility to configure triggers, automation, and custom reporting on top of each integration. Campaign Monitor focuses mostly on one-way data sharing.

So while Campaign Monitor covers the basics well, Klaviyo is superior in terms of deep integration capabilities.

Winner: Klaviyo

The Klaviyo Campaign Monitor comparison shows that Klaviyo is the clear winner. Thanks to strong native app support plus API extensibility, Klaviyo has the best platform integrations for successful email marketing campaigns. It enables more seamless connectivity across your martech stack to centralize data and maximize automation based on a wider range of customer touchpoints.

7. Pricing


Klaviyo offers a free plan covering up to 10,000 contacts. Paid plans scale from $45/month up to custom enterprise pricing.

Key features like segmentation and email automation are available in all pricing tiers without subscriber limits. You pay primarily for contact volume. Bolt-on premium features like SMS, predictive tools, and Salesforce integration carry additional costs.

The marketing automation software gives you access to the full-scope platform capabilities regardless of tier. Bolt-on premium tools let you pay only for the extras needed.

Campaign Monitor

With a 4.7/5 average across 350+ Capterra reviews, Campaign Monitor by Marigold also earns stellar feedback for running targeted email campaigns. Users highlight email campaign design, deliverability, ease of use, and great customer support as advantages.

Less positive reviews wish the platform integrated better with more third-party apps. Some also feel the basic UI lacks more advanced configuration capabilities.

Winner: Klaviyo

Both platforms earn outstanding reviews from customers. But with higher overall review ratings and praise for the platform’s breadth of capabilities, Klaviyo slightly edges out Campaign Monitor when it comes to public reputation. Consider both equally great options though.
