Comprehensive Marketing Tool with Room for Improvement

What do you like best about the product?
I really appreciate how Klaviyo helps us track customer behavior, which is quite useful. The customizable SMS, chat, and emails are great for our marketing needs. I also like the automatic email and SMS triggers based on customer behavior, which makes our marketing strategies more efficient.
What do you dislike about the product?
I think Klaviyo could really benefit from better analytics for customer metrics. The platform isn't the easiest to navigate, and it could definitely be more visually appealing. Setting it up wasn't exactly quick and easy, but after that, it's been great to use.
What problems is the product solving and how is that benefiting you?
Klaviyo offers customizable SMS, chat, and email, helping us track customer behavior and set triggers based on that behavior.

Klaviyo helped us simplify reactivation without losing personalization
Reviewed on Sep 30, 2026
Review provided by G2
What do you like best about the product?
Segments and Flows are where Klaviyo becomes genuinely useful for content work, because we can stop treating every customer as if they’re all at the same stage. We break audiences out into inactive customers, repeat buyers, people who viewed specific categories, and users with different purchase histories, and then tailor the copy, product selection, and CTA to match those differences. Multi-branch flows make this much easier to manage when language, region, or behavior changes what the message should be, since we don’t have to build a long chain of binary splits just to land on the right version. Product Feeds, sign-up forms, and the campaign editor also help keep creative connected to real customer data, rather than producing content in isolation. Social Marketing has been especially helpful because it lets us bring UGC and social content into email, SMS, and flows without having to recreate the same idea from scratch for every channel. Design can build the core asset once, and then content can adapt the message around it, instead of requesting three slightly different versions at the last minute.
What do you dislike about the product?
The biggest trap is over-personalization. Just because the data exists doesn’t mean every email needs five conditions, three dynamic product blocks, and completely different copy for every micro-segment. We tried going that far, and the editorial review process became painful very quickly. It was harder to catch inconsistencies, harder to approve the message with confidence, and easier for one branch to drift away from the core campaign idea. Now we only personalize deeply when it truly changes the intent, the value, or what the person needs to hear next.
What problems is the product solving and how is that benefiting you?
We ran a reactivation campaign that, at first, sent virtually the same content to our entire inactive base. That meant we were mixing customers who had purchased just a few months earlier with people who hadn’t interacted for more than a year. Using Klaviyo Segments, I separated those groups based on recent activity, purchase history, and browsing behavior. From there, we rebuilt the program as a Flow instead of continuing to manage separate submissions. For the most recent segment, we leaned on editorial content and news. For colder contacts, we adjusted the message, CTA, and proposal so they had a clearer reason to come back. We also added Product Feeds tied to the categories they had previously viewed or purchased. Our first version of the flow ended up being too complex because we added several conditional splits for history, category, and engagement level, and reviewing every path before publishing was taking too long. I simplified it by using a multi-branch split and keeping only the differences that truly changed the content. We also used Personalized Send Time so we didn’t have to manually schedule each segment. The biggest workflow improvement was moving from preparing several nearly duplicate campaigns to maintaining a single journey with clear rules. That reduced repetitive work, made content review easier before publishing, and helped us better understand which message fit each type of customer. In our case, Klaviyo stopped being just the tool we used to send emails and became the place where we organized the full reactivation logic.

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.
