    Review provided by G2
    What do you like best about the product?
    I like that Klaviyo is a full-fledged product with lots of different add-on features, including SMS, WhatsApp, social media management, among others. It allows us to have an all-in-one solution that avoids having multiple subscriptions with different software providers. The initial setup was very easy, and the move from Mailchimp to Klaviyo was due to its expanded functionality and more value for the price.
    What do you dislike about the product?
    Email editor should be more expansive with more email examples to take and use from

    I use Klaviyo to send emails, keep our customers updated on promotions, and send automated emails based on triggers. It provides an all-in-one solution, eliminating the need for multiple subscriptions.

    Makes Email Marketing Much Easier

    Reviewed on Aug 07, 2026
    Review provided by G2
    What do you like best about the product?
    What I like most about Klaviyo is how simple it makes email marketing. I use it mainly to build automated flows like welcome emails and abandoned cart reminders, and the visual Flow Builder makes it easy to update everything without much effort. I also rely on customer segments to send different campaigns based on purchase history or engagement instead of emailing everyone the same message. After each campaign, I usually check the reporting dashboard to see what worked and what needs improvement. It has saved me a lot of time and made managing campaigns much easier.
    What do you dislike about the product?
    The biggest issue I've run into is the pricing. As our contact list grew, the monthly cost increased pretty quickly, so it's something we have to keep an eye on. I also needed some time to get comfortable with the more advanced automation flows because there are a lot of options. The reporting is useful, but I sometimes have to dig through multiple reports to find the metrics I'm looking for. None of these are deal breakers, but I'd like to see simpler reporting and a pricing model that's a little friendlier for growing teams.
    What problems is the product solving and how is that benefiting you?
    Before we started using Klaviyo, most of our email campaigns were created manually and it took time to organize different customer lists. Now I use customer segments and automated flows to send welcome emails, abandoned cart reminders, and follow-up campaigns without having to do everything manually. It also makes it easier to see how each campaign performs because I can check the reports in one place. Overall, it has saved time, reduced repetitive work, and made it much easier to manage our email marketing.

    Phenomenal Marketing Automation with Klaviyo

    Reviewed on Jul 29, 2026
    Review provided by G2
    What do you like best about the product?
    I use Klaviyo for marketing automation and love how it makes launching campaigns efficient, especially targeting my registered users and prospects who have interacted with my website. The hyper-personalization feature is phenomenal, outperforming other tools I've tried like Constant Contact and Mailchimp. I also appreciate the ability to launch further campaigns based on user behavior without losing track, which is crucial for reaching a wide audience efficiently and economically. The RFM matrix helps me easily determine which customers are likely to make orders, which simplifies my marketing strategy significantly. The initial setup was quick; it took just an hour to implement key flows and launch them, which is a big time-saver. I also use it with other platforms like Shopify and my website, and I find Klaviyo integrates very smoothly with these and other tools, like Adobe. Additionally, the new features they're launching, even in beta, are impressive, such as the campaign auditing feature that provides targeted prospect numbers even before we launch campaigns.
    What do you dislike about the product?
    No, the beta version for live campaing audit is a real saviour
    What problems is the product solving and how is that benefiting you?
    I use Klaviyo for marketing automation, reaching out to registered users and prospects, which boosts our revenue. It provides detailed insights at my fingertips, tracks engagement, and simplifies influencer connection without diving into social media profiles.

    Easy Email Campaigns with Powerful Shopify Segmentation

    Reviewed on May 28, 2026
    Review provided by G2
    What do you like best about the product?
    Klaviyo makes it easy for me to run email marketing campaigns, and it integrates well with my Shopify store. I especially like being able to segment my audience and target different groups based on their actions.
    What do you dislike about the product?
    Klaviyo doesn’t have the best selection of email templates, which makes creating emails more difficult. I often end up importing templates from other providers, and that extra step takes time.
    What problems is the product solving and how is that benefiting you?
    It helps me understand my audience better—what they like, what they don’t like, and which promotions they actually care about. It also helps me stay top of mind with potential customers by sending reminders that encourage them to add items to their cart and complete the purchase.
