Our team tests eCommerce apps and publishes reviews that are unbiased and not influenced by payments we receive from some of the app developers.
If you've spent any amount of time researching email marketing automation platforms, you've likely noticed one name popping up again and again—Klaviyo.
In a nutshell, Klaviyo is a marketing automation platform used primarily for email and SMS marketing. It's an excellent option for those e-commerce platform users who want to kick their targeted marketing strategies up a notch and improve their performance. It supports integration for most major e-commerce platforms, and the app facilitates easy setup, omnichannel marketing, and customer data collection for future marketing campaigns.
If you're interested in using an email marketing automation platform and making it work with other marketing channels, read on as we break down absolutely everything you need to know about Klaviyo.
What Is Klaviyo?
Klaviyo is a cloud-based email and SMS marketing automation tool available for many of the major e-commerce platforms currently available. Through the Klaviyo dashboard, users can deliver super-targeted email campaigns based on predictive analytics that includes customers' previous purchasing, refund requests, in-store visitor activity, and email interaction history.
These predictive analytics are then leveraged to take the guesswork out of email marketing and create high-performing automated emails and SMS messages that target customers with ultra-personalized content.
Who's Klaviyo for
The Klayivo app is best for small to large e-commerce stores that wish to automate their email marketing efforts while still maintaining control over their branding style and marketing vision.
What Makes Klaviyo Stand Out
- Customizable Marketing Campaigns & Precise Customer Targeting E-commerce marketers can shift and pivot their marketing strategies as they see fit and target customers based on their in-store behavior, location, and their individual interactions with previous campaigns.
- Facebook Advertising Integration This allows e-commerce marketers to not only advertise to targeted audiences but also to add any subscribers to Facebook Ad Forms, all within the platform.
- Marketing Automation Klaviyo can fully automate various marketing tasks. It facilitates marketing avenues that assist in building strong marketing flows, tracking customer behavior, and automating triggered emails that reduce marketing costs.
Pros
- Highly customizable marketing campaign
- Precise customer targetting
- Painless Facebook Ad Integration
- Seamless marketing automation
- Pre-built templates and automation
Cons
- Advanced functionalities can be complicated
- Inattentive customer support
- Tiered pricing system can be pricey
Features
Klaviyo has a ton of great features that are sure to drive the success of your e-commerce business.
First up, the setup is headache-free and uncomplicated. Once the setup is complete, dive in and start pulling unlimited real-time customer data to create personalized content for your eagerly awaiting audience.
Klaviyo also features ROI-based reporting. That way, you can easily track exactly how much your marketing efforts are costing and just how effective your launched campaigns are.
The app also supports comprehensive and easy A/B testing, allowing you to monitor how different versions of your campaigns perform. Once you have this info, you'll be able to fine-tune your marketing efforts and get the highest-converting variant possible.
Email segmentation allows users to target their customers through their behavior and transactional data to enable target promotions to be more effective and precise.
Pre-built email responders allow for automated flows that are both effortless and time-saving.
Klaviyo Pricing
When it comes to pricing, Klaviyo follows a monthly subscription-based service. If you have up to 250 email contacts and can get away with sending between 15 and 150 SMS/MMS messages (depending on the region), you can use the free plan. Anything more than that costs actual money. Paid plans provide extra features like additional chat support, 2-way conversations, opt-in forms, and more.
Klaviyo's Shopify app charges separately for SMS and email contacts, allowing users to upgrade as they grow their companies and channels. However, on its website, Klaviyo offers free email and email & SMS plans.
The plans can be scaled depending on the number of contacts and the number of monthly SMS/MMS credits. The credits will get you a different number of messages depending on the region. You can see the exact point costs below.
| | USA | Canada | UK | AUS | NZ |
|---|---|---|---|---|---|
| SMS (credits) | 1 | 3 | 5 | 4 | 10 |
| MMS (credits) | 3 | 5 | N/A | N/A | N/A |

Usability
With all the different features Klaviyo offers to its customers, sometimes things can get a little complicated.
Although the setup is usually painless and the platform's interface easy to navigate, some users may find using it a little overwhelming at first due to the high customizability.
To help you out, the Klaviyo team has created a ton of resources on their website for you to take advantage of. Anything from webinars to live training, the Klaviyo team is making it easier and easier to use their software.
Support
If there is one consistent criticism of the marketing platform, it's probably that of its customer support. While some cannot praise Klaviyo enough for its seamless integration with their e-commerce platform of choice, other Klaviyo reviews, left by current and previous users, don't rate the customer support highly.
To counter this criticism, they now offer multiple avenues of contact for their customers, including chat support, email support, and a community forum that is available 24/7.
Wide Integration
Klaviyo integrates with a wide range of major e-commerce platforms, social media platforms, and third-party marketing software, including but not limited to:
- WooCommerce
