You've probably used or heard about Mailchimp because it constantly ranks among the best email marketing platforms. Yet, Klaviyo may be the better choice if you have an ecommerce business, especially a large enterprise. 

Klaviyo is the king of email and SMS marketing in the ecommerce world, and we’ll tell you why in our blog posts. First, its free plan is incredibly robust and includes things like automation, flows (journeys in Mailchimp), and scheduled email campaigns that are only available on Mailchimp’s paid plans. 

In this write-up, we introduce Klaviyo for headless ecommerce. We discuss what Klaviyo can do and walk you through its login, pricing, and API functionality. 

Read along. 

What is Klaviyo for Headless Ecommerce?

Klaviyo is a marketing automation platform designed to help businesses acquire, retain, and grow their customers through email and SMS marketing. It is built specifically for ecommerce stores, especially headless ones like Shopify, Magento, and BigCommerce

Thanks to its API-first approach, Klaviyo integrates seamlessly with ecommerce platforms and boasts nearly limitless integrations. 

This email marketing tool offers various handy features that help businesses create personalized and targeted marketing campaigns. It boasts many advanced features, such as email automation, email segmentation, drip campaigns, and pre-built reports.

Klaviyo has powerful reporting and analytics features for tracking results and improving businesses’ overall marketing ROI.  

The tool allows you to segment your audience based on their preferences and behavior, schedule and send out automated emails triggered by specific actions, and track the results of your campaigns in real time.

Key Things that Klaviyo Can Do

While Klaviyo is primarily an email marketing tool mainly targeted to large enterprises, it has many functionalities that can benefit businesses of all sizes. 

Let’s break down what it can do to boost the growth of your ecommerce business. 

Email marketing

As already pointed out, the primary function of Klaviyo is email marketing. The tool allows you to create and send targeted email campaigns to your prospective and actual customers. You can design email campaigns based on the target’s browsing behavior, demographics, purchase history, and other data points. 

You can also use Klaviyo to automate your email marketing, such as sending welcome emails to new customers or abandoned cart emails to customers who have left items in their carts. 

You can get creative with your email campaigns, and Klaviyo will help fuel them to see them drive the desired results. 

SMS marketing

While Klaviyo did not originally support the sending of promotions to customers via text messages at its inception, that has changed over recent years. The marketing platform now supports SMS (short message service) marketing, allowing you to push your promotional content to customers in SMS form.

SMS can be an excellent way to send promotional offers, appointment reminders, or order updates due to their immediacy and directness. 

Recent data shows that SMS marketing reaches over 98% of smartphone users. Even better, users open and read over 95% of SMS messages within the first 3 minutes of delivery, making them incredibly effective in driving action. 

Aside from the high open rates, personalized SMS messages also enhance the customer experience and can go a long way in fostering brand loyalty and promoting repeat purchases.

Email and SMS automation

With Klaviyo, you don't have to remain hands-on throughout to keep your email and SMS campaigns running. You can leverage the platform’s automated email and SMS campaign features to simplify your work. 

Klaviyo can send your campaign messages based on specific trigger events, such as abandoned carts, welcome messages, or order confirmations. 

  • H4: Customer segmentation

You have the option to divide your customer base into groups based on shared characteristics or various demographics when using Klaviyo. Such segmentation allows you to send more relevant marketing messages and achieve higher response rates. 

Klaviyo has a customer data platform (CDP) that lets you collect and store all of your customer data in one place. You can use this data to personalize your marketing campaigns and improve your customer relationships.

Reporting and analytics

Reporting and analytics are a crucial part of any marketing campaign. Klaviyo provides you with detailed reports and analytics on your marketing campaigns. This data can help you track your progress and see what's working and what's not. Track the performance of your marketing campaigns and get insights into customer behavior.

Klaviyo Login: Getting started with Klaviyo

The first step to using Klaviyo is to access your dashboard. This is where all the tools you need to manage your marketing campaigns and track your results are domiciled.

However, you must create an account first to access your dashboard. So here is how to do it and get started with Klaviyo for headless ecommerce. 

  • Head over to the Klaviyo login page and fill out the form provided.

  • Provide your preferred login information, including your email address or username and password.

  • Provide your business information, including the company name and website. 

  • Provide your contact information to complete the form. 

Once you've filled in all the required fields with the right information, consent to the Klaviyo terms and conditions and sign up for the account to access your new Klaviyo dashboard. 

Next, you can choose your objectives and describe your ecommerce business to Klaviyo to help it deliver a more personalized experience.

Klaviyo has a user-friendly interface that should get you started even without much technical knowledge. 

To manage your account, you will need to log in to your dashboard. Simply head over to the Klaviyo login page by typing ‘’ into your browser or hitting the login button on the site’s home page whenever you want to access the account.

This will allow you to enter your email address or username and password.

What if you are having trouble logging into your Klaviyo account?

Login problems can occur due to various issues, restricting your access to the Klaviyo dashboard. Thankfully, you can always resolve these issues easily with a few simple fixes if you know where to look. 

Here is the list of things you can do to regain access to your Klaviyo account when having login problems. 

  • Double-check the email address to ensure you're entering the correct information. Do the same with the password, as a small omission will render your login incorrect. Logins are case-sensitive, so make sure you include any capital letters where appropriate. 

  • Log into your account using a different web browser. Sometimes, the problem can be related to the browser you're using. If this is the case, login into the account from a different web browser should provide the needed workaround. 

  • Clear your current browser's cache memory and cookies. Web browsers store some of your recent browsing data in their cache memory to help speed up access when logging back in. Unfortunately, these data can sometimes cause conflicts, so clearing them should help eradicate the issue.

  • If everything fails, contact Klaviyo support for further assistance. This should be your last resort when having trouble with your Klaviyo login. 

Klaviyo API: Integrating Your Site with Klaviyo 

Once you've created your Klaviyo account, you can easily integrate it with your ecommerce website and headless commerce platforms like Shopify, Magento, and BigCommerce.

Klaviyo supports countless integrations that open up infinite opportunities for your business. Integrating your headless ecommerce site with Klaviyo enables ease of access and flow of data across your digital ecosystem. This is where Klaviyo API comes in.

What is Klaviyo API?

Klaviyo API (Application Programming Interface) is a powerful tool that allows developers to create custom integrations and applications that connect to Klaviyo. This API provides access to all of Klaviyo's data and features, such as the following: 

  • Customer data, including profile information, purchase history, and engagement data

  • Marketing campaigns, including active campaigns, segments, and automation

  • Reporting information, including performance data and key insights

With Klaviyo API, you can programmatically access and manage data in the platform and build your business. The API can be used to build custom integrations, automate tasks, and create new marketing campaigns.

This is a RESTful API, which means that it uses standard HTTP requests to communicate with Klaviyo's servers. The API is documented in JSON, making it easy to use with various programming languages.

To use the Klaviyo API, you'll need to create an API key. You can do this by navigating to the Settings tab in your Klaviyo account and clicking on API keys. You can then use the API key to authenticate API requests. 

Klaviyo provides a number of resources to help you get started with the API. These include the API documentation (detailed information on how to use the API), code samples of various programming languages, and a developer community for getting help and support.

Examples Of How You Can Use the Klaviyo API

  • Create custom integrations—you can use this powerful tool to create custom integrations between Klaviyo and other applications. For instance, you could create an integration that automatically adds new customers to your Klaviyo account when they sign up for your website.

  • Build custom applications—you can use the API to build custom applications that use Klaviyo data and features. A good example is an application that analyzes customer data to identify trends and opportunities. The API allows you to explore the limits of your creativity and developer acumen.

  • Automate tasks—you don’t have to be limited to the automation capabilities that come with Klaviyo. Instead, you can use the API to extend the functionality of Klaviyo and automate tasks in ways that suit your business. 

Klaviyo pricing

Earlier in this blog post, we said that Klaviyo has a robust free plan that includes exciting features that you only find on the paid plans of competing platforms like Mailchimp. 

While Klaviyo’s free plan is definitely enticing, its paid plans are the area of complaint for some customers who find them rather expensive. 

In spite of the relatively higher prices, Klaviyo offers some of the most robust features, making it an excellent choice for larger enterprises. You get what you pay for, and if you have a large business, you’ll find the pricing totally worth it. 

The platform allows you to unlock incremental growth and build customer relationships at scale, providing better ROI (return on investment) than any enterprise-grade email marketing solution on the market. 

That said, Klaviyo offers various pricing plans to cater to different business needs and sizes. Specifically, the platform currently has a free plan and three paid pricing plans for email and SMS marketing.
