Comparison

Forward-thinking brands choose Stamped over Klaviyo to boost customer acquisition and accelerate business growth

Stamped

Stamped, founded in 2016, offers solutions for reviews and ratings, loyalty and rewards, referrals, net promoter scores (NPS), user-generated content, and data-driven insights. Stamped’s mission is to “help ecommerce brands of all sizes grow their businesses through genuine relationships with their customers.” Stamped currently serves over 75,000 ecommerce brands, including Purple, Tentree, and Kitsch.

Customer Profile

While Stamped helps brands of all sizes accelerate their business growth, it’s best suited for mid-market and enterprise brands based on the available features and pricing plans. This includes the Full Suite option for brands looking to combine reviews and loyalty, and the Enterprise pricing plan with custom rates and a dedicated customer success manager. Stamped also has over one hundred agency partners available to help mid-market brands who don’t have a dedicated developer. Most of Stamped’s customers are in the health, wellness, beauty, apparel, and fitness industries, though we also work with home and garden, food, and sports brands as well.

Features

Overview
Stamped offers two products: Loyalty and Reviews. Loyalty maximizes engagement and customer lifetime value, while Reviews gain insights and drive increased conversions, both on-site and through other marketing channels like email, search, and social media. Both products can be leveraged together to help merchants “establish brand credibility and accelerate business growth”.

With Stamped Reviews, brands can collect and showcase product and site reviews to boost conversions and uncover actionable insights. They can gather, moderate, and analyze reviews, highlight reviews on dedicated landing pages, product pages, site widgets, and Google search results, and leverage reviews to boost SEO rankings and enrich marketing content. Lastly, brands can curate user-generated content, conduct NPS surveys, and contextualize reviews for smarter business decisions and accelerated business growth.

Brands send review requests via email and SMS, where customers directly submit their reviews using the in-email form without needing to navigate to another landing page or website. Brands can also include custom forms to ask more specific questions and get a better understanding of their customers. They can use StampedIQ’s Smart Assist feature to help customers write higher-quality reviews. Brands can use Checkout Reviews and Community Q&A to ask and answer customer questions. Site visitors can also sort and browse reviews by topic filters, star ratings, and search terms. Lastly, brands can incentivize and reward customers for writing reviews by sending coupon codes, leading to increased chances of conversion.‍

Stamped’s user-generated content feature helps brands collect, moderate, and organize photos and videos obtained from reviews. Brands can filter media by color, quality, and objects, group media into albums to create visual showcases, design social and retargeting ads, and create shoppable Instagram galleries. These media-centric features help brands stand out from their competitors and boost their on-site conversions.

Next, Stamped’s net promoter score (NPS) feature helps brands measure customer happiness and monitor the percentage of detractors, passives, and promoters respectively. Brands send survey requests via email, website, SMS, and direct links, where customers provide a rating on a scale of 0 to 10 and provide context for their rating. Brands can identify recurring trends and topics to discover what’s working and what needs to be improved.

Lastly, StampedIQ leverages artificial intelligence and machine learning to produce actionable insights at scale. In addition to Smart Assist, brands can use Sentiment and Topics Analysis to improve shopper review accuracy, prevent them from posting false positive reviews, convert reviews into contextual overviews, and make adjustments based on customer sentiment. StampedIQ also helps brands curate their visual content and manage UGC for landing pages, product pages, and social media. All of these tools make reviews easy for customers to write and easy for brands to moderate, curate, and leverage.

Platforms & Integrations
Stamped works with Shopify and Shopify Plus, BigCommerce, and WooCommerce. It can also be implemented on a headless platform or a custom/generic ecommerce platform like Magento, Wix, and Shoplazza with HTML. Lastly, brands can easily import their existing reviews into Stamped with a CSV file and request reviews for past orders to improve their review conversion rates.

Stamped offers multiple integrations with tools that brands already know and love for marketing automations, syndication, email and SMS marketing, social commerce, payment management, and more. This includes Google, Facebook and Instagram, Attentive, Gorgias, Klaviyo, Rebuy, Tapcart, and KnoCommerce.

Data & Analytics
Brands also get access to powerful customer insights in the Reviews dashboard. They can identify top customers and products by reviews, top keywords and searches, total review request emails sent, and more. These data points help brands learn more about their customers and inform their strategies for driving engagement, conversions, repeat purchases, and customer retention. Stamped customers on a full-suite plan can also view their reviews and loyalty data in one place.

Full-suite pricing plans start at $279/month billed monthly or $229/month billed annually.

Pros and Cons

Stamped’s Reviews solution offers features similar to other platforms like Yotpo, Junip, and Okendo. However, Stamped provides more value for brands looking to acquire new customers and boost conversions in several ways.

To start, Stamped’s fair and transparent pricing structure makes it easy for brands to get a clear sense of which plan best suits their budget and needs. Compared to other competitors, brands don’t need to pay for the most expensive plan to get access to the features they need. For example, Yotpo customers need to pay a custom rate to get CSS customization, while Stamped customers only need to pay $59/month (Yotpo’s Premium plan vs. Stamped’s Premium plan). Brands can also subscribe to Stamped on a month-to-month basis without needing to commit to a long-term contract. Most other reviews platforms do not offer the flexibility of monthly and annual pricing plans.

Stamped has world-class onboarding and support teams to help brands create, manage, and optimize their reviews strategy, as well as ongoing communication for product fixes, updates, and so on. It also offers a contract buyout option, making it easy for brands to switch platforms without paying excessive fees or significantly impacting their customers.

Feature-wise, Stamped customers can easily customize several aspects of their landing page, widgets, and emails without needing a dedicated developer. There are also multiple display widgets available to help brands highlight their product and site reviews in different areas of their website, making it easier for customers to make a purchase decision. Stamped can syndicate reviews across multiple websites, domains, locations, countries, and more, as well as push reviews to Google Shopping Ads, search engines, and social media.

Stamped customers also have access to features that aren’t widely available on other reviews platforms. For example, while platforms like Yotpo have a custom forms feature and Okendo has its Okendo Surveys product, Stamped Reviews includes a built-in NPS feature where brands can collect reviews and customer satisfaction scores at the same time, making it simple to measure customer happiness and view actionable feedback in one place. Stamped’s shoppable Instagram galleries are another unique and highly useful feature. Most reviews platforms only offer a social push option to Facebook and/or Meta syndication, but with shoppable Instagram galleries, brands can drive more social engagement and more sales where customers can make purchases without needing to leave their website. Finally, Stamped’s smart social banners help brands turn reviews into compelling visual content and high-performing ads. These banners are easy to create, automate, and publish without needing a dedicated designer or marketer, and can be used to drive more engagement and sales.

Lastly, Stamped Reviews customers can take full advantage of the Full Suite option to leverage Loyalty as well. Together, both products drive more sales, engagement, retention, and new business. For example, brands can ask customers to write a review in exchange for reward points, resulting in increased trust from potential customers and increased loyalty from existing ones. Loyalty also increases customer retention and lifetime value, and gives brands more opportunities to drive sales and engagement with both new and existing customers.

💡 Learn more about Loyalty to get the most out of your Stamped experience.

The main disadvantage of Stamped is that it only offers Reviews and Loyalty, which might not appeal to brands looking for platforms with other products like subscription services and SMS marketing. However, Stamped’s integration and agency partners guarantee that brands get all the features and assistance they’re looking for without needing to lock themselves into a single ecosystem. Brands don’t need to compromise to provide a well-rounded experience for their customers or struggle to connect their new loyalty program to their existing tech stack. Stamped is focused on delivering the best possible Reviews and Loyalty experience, from customer onboarding to product features to ongoing support. Stamped’s team of knowledgeable, customer-driven experts ensures that brands get a quality reviews solution and achieve their business goals.

Klaviyo

Klaviyo was founded in 2012 by Andrew Bialecki and Ed Hallen. It offers solutions for reviews, email marketing, SMS marketing, and push notifications. Klaviyo’s mission is to help brands “turn all of your customer data into hyper-personalized messages that shoppers want.” Klaviyo currently serves over 100,000 ecommerce brands, including Glossier, Nuun, and Bloom Nutrition.

Customer Profile

Klaviyo is best suited for mid-market businesses and enterprise brands. The majority of Klaviyo’s customers are in the apparel, beauty, food and beverage, and health and wellness industries.

Note: As Klaviyo Reviews is a brand-new product, the onboarding process and support structure is currently unknown.

Features

Overview
Klaviyo offers four different products: Email, SMS, Mobile Push, and Reviews. They’re intended to work together so brands can “create, measure, and optimize any combination of email, SMS, and mobile push messages” and “get the most out of [their] product reviews with [their] data consolidated in one platform”.

With Klaviyo’s Reviews, brands can collect reviews and customer data, display and manage their product reviews, and give shoppers the confidence they need to make a purchase. They can send automated review requests, gather insights from custom questions, design on-brand experiences, segment users based on review data, and build trust with verified reviews.

Note: Klaviyo Reviews currently does not have the ability to collect video reviews.

Platforms & Integrations
Klaviyo Reviews works with Shopify and Shopify Plus. Klaviyo also offers multiple integrations with tools for helpdesks, loyalty and referral programs, affiliate and influencer marketing, and so on, including Gorgias, Gatsby, Rebuy, Zapier, and Stamped.

Note: Klaviyo Reviews does not work with most ecommerce platforms that are available for other Klaviyo products, including BigCommerce, WooCommerce, Wix, and Square Online. It also can’t be implemented on a headless platform or a custom/generic ecommerce platform. Klaviyo also lacks several popular integrations that compete directly with other Klaviyo products, including Hubspot, Attentive, Mailchimp, and Omnisend. Lastly, Klaviyo does not offer review syndication with popular tools like Bazaarvoice and Meta.

Data & Analytics
Brands also get access to a Reviews analytics dashboard, where they get insights into their reviews performance. This includes the number of reviews collected, review response rates, and their average review rating. Customers can also view their overall Klaviyo analytics dashboard to look at delivery metrics and reviews metrics. This allows them to build flows and segments based on customers’ order status and criteria.

Note: Delivery metrics are only available for customers on a paid plan.

Pricing Plans

Klaviyo Reviews is currently an add-on product, with its pricing structure as follows:

  • $25/month, up to 250 monthly review requests
  • $90/month, up to 1,000 monthly review requests
  • $175/month, up to 2,000 monthly review requests
  • $300/month, up to 3,500 monthly review requests
  • $500/month, up to 10,000 monthly review requests

Customers can also get a custom plan by contacting Klaviyo’s sales team. They must be a Klaviyo Email customer to use Klaviyo Reviews, which ranges from $0/month with 0 to 250 customers to $1,955/month with 145,001 to 150,000 customers.

Pros and Cons

Klaviyo offers similar features compared to other reviews platforms, including custom questions, community Q&A, and coupon incentives. It also works seamlessly with Klaviyo’s other products, making it easy for existing Klaviyo customers to build reviews-related flows and segments. Lastly, Klaviyo has a dedicated tutorial, help center, and community forum to help brands optimize their reviews strategy. However, Klaviyo Reviews is a very new product and is therefore lacking in several key areas, including integration support, review syndication, and feature depth.

To start, it doesn’t have a native loyalty application, and combining Klaviyo with another loyalty platform is likely to result in significantly higher costs than solutions like Stamped’s Full Suite. As mentioned previously, since Klaviyo Reviews is a brand-new product, the onboarding process and support structure is currently unknown.

Klaviyo Reviews is only available for Shopify and Shopify Plus customers, excluding existing Klaviyo customers who use other ecommerce platforms like BigCommerce or WooCommerce. Klaviyo users also can’t get Klaviyo Reviews on its own, meaning they may end up paying for features they don’t plan to use. As mentioned previously, Klaviyo also doesn’t offer several major integrations that conflict with its Email, SMS, and Mobile Push products, including Hubspot and Attentive. This makes it difficult for brands looking to add Klaviyo Reviews to their existing tech stack.

Features-wise, Klaviyo does not offer review syndication outside of Google Shopping and does not offer any reviews-specific social push, meaning brands can’t share reviews across multiple websites, to major retail websites like Walmart and Target, or on social platforms like Facebook and Instagram. Next, there is no built-in NPS feature, which can be disadvantageous for brands looking to get deeper insights into customer sentiment.

Brands can’t collect site reviews, only product reviews, making it more difficult to gauge customer sentiment on things like shipping and customer service. They also can’t collect video reviews, only photos, limiting their range of user-generated content. Custom forms are limited to multiple-choice and range questions only, meaning brands can’t ask customers to write their own answers. There are only four widget types: star rating, review summary, review list, and carousel, with no options for a dedicated reviews landing page or additional widgets like side drawers and badges. It does not offer any options for displaying user-generated content in a dedicated visual gallery.

Lastly, while Klaviyo Reviews is designed to push customer data through flows and into segments to work with other Klaviyo solutions, it does not currently offer in-depth, reviews-specific insights. For example, while brands can see their review response rates and average review rating, they cannot easily identify top products by reviews or top keyword searches.

By comparison, Stamped offers a Full Suite solution where customers can leverage reviews and loyalty together at a reasonable rate. Stamped’s pricing plans are also highly flexible with both a monthly and yearly option, where annual plans come with a 20% discount. Finally, Stamped has dedicated onboarding and support teams to ensure business growth and success, including customer success managers who work with brands on a one-to-one basis.

Compared to Klaviyo, Stamped not only works with Shopify and Shopify Plus but with BigCommerce and WooCommerce, and can also be implemented on headless or custom/generic ecommerce platforms. Stamped users also get access to a wide variety of integrations they already know and use, including Bazaarvoice, Attentive, and Meta.

Stamped also offers review syndication made easy, helping brands distribute reviews across multiple websites, domains, locations, countries, and more. Stamped’s built-in NPS feature makes it easy for brands to measure customer happiness and optimize their marketing strategies based on actionable feedback.

Stamped users can collect both product and site reviews to get deeper insights into both customers’ opinions and shopping experiences, as well as collect both photos and videos to enrich their visual marketing. With Stamped, brands can also build dedicated landing pages and use a wide range of review widgets like side drawers and badges to help customers make a purchase decision no matter where they are on their website. They can also utilize features like smart social banners, shoppable Instagram galleries, and media albums to make the most of customers’ user-generated content and drive more sales and engagement.

Lastly, Stamped’s analytics dashboard provides in-depth, actionable insights to help brands better understand and serve their customers, including top customers and products by reviews, top keywords and searches, and more. Compared to Klaviyo’s basic analytics, StampedIQ is especially powerful for data-driven optimization, helping brands improve review accuracy and collect quality feedback.
