Klaviyo: Email Marketing & SMS

The experience with Klaviyo has been outstanding. The app works well with Shopify and allows for the most compete view of our customer experience. We have used other ESP's and this integration is top notch!

Klaviyo stated they have protections in place to keep bots from signing up creating fake emails. I am a small business and my email is full of fake emails. I try to delete them but they don’t disappear. I can’t keep ahold of any one in support until I upgrade and pay a monthly fee or lower the amount of emails in my account which is not working. I guess you can’t get help unless you pay them. It is a difficult platform to use also. The best option is to delete my entire account and go to a different email provider. I don’t want to work with a company that can’t help unless you pay them!!

Klaviyo offers a ton of great features and powerful tools, especially for building flows and creating segments. The in-app designer is stable, intuitive, and easy to work with, and the documentation is clear and helpful when you need guidance. I’ve found the platform overall very easy to use, and I really enjoy the classes — they’re informative and well done. The CSM reps I’ve worked with have also been very helpful.

Strong marketing capabilities and automation, but improvements in event tracking reliability, documentation, templates, and customer support would make the platform significantly better for growing ecommerce brands.

The smartest marketing tool in my business"
Klaviyo completely changed the way I communicate with my customers. The segmentation is precise, the flows run on their own, and the analytics give me a clear picture of what's working and what's not. After switching from another platform — there's no going back.

Klaviyo's capabilities and its seamless integration with Shopify have made a real difference for my business. I hesitated to switch to it because it was more expensive than what I was using, but it pays for itself and more every month.

As the founder of a small Shopify DTC brand, Klaviyo has been a really helpful tool for managing customer communication and marketing automation. It makes it much easier to build email flows, campaigns, and segments without needing a large marketing team.

I also appreciate the ecosystem around Klaviyo. Tools like the Grid & Pixel Email Autopilot integration have helped streamline the process of creating and managing email content, which frees up time to focus on other parts of running the business.

Overall it's a powerful platform for ecommerce brands that want to stay connected with their customers and automate parts of their marketing without overly complex setups.

I've used several email platforms, and Klaviyo is the best option, hands down, for e-comm on Shopify. The integrations and relationship between the platforms is key, and I've been really happy with the email/sms software as well. Flows are excellent and the triggers integrate really well between the two platforms.

Klaviyo is hands down one of the most powerful email and SMS platforms available for Shopify. The segmentation, automation, and data depth are best-in-class. When it’s set up properly, it can absolutely drive meaningful revenue.

That said, it really shines only if you have someone actively managing it. To get full value, you need consistent flow optimization, campaign strategy, list hygiene, testing, and performance monitoring. It’s not a “set it and forget it” tool, it rewards attention and strategy.

I’d also love to see more flexibility in the pricing structure. When performance fluctuates month-to-month, the fixed pricing model can feel slightly disconnected from results. A structure that better reflects engagement or revenue impact would make it even stronger.

Overall, it’s still the best tool in the space hands down, just make sure you’re ready to invest the time (or team) to unlock its full potential.

Klaviyo is hands-down one of the most powerful email and SMS platforms out there for ecommerce. The depth of their analytics is where they really shine. From revenue attribution to flow-level performance and segmentation insights, Klaviyo gives you the kind of data that actually helps you make smarter decisions and squeeze more sales out of every campaign.

The segmentation and automation capabilities are excellent, and once you know your way around the platform, it becomes a serious growth engine. If you care about understanding customer behavior and optimizing lifecycle marketing, Klaviyo is hard to beat.

That said, pricing is the biggest downside. Being charged for all profiles in your account—even ones you never email—can feel frustrating, especially for growing brands with large lists. It would be much more fair (and sustainable) if pricing were based only on the profiles you actively send emails to.

Overall, Klaviyo is an elite tool with best-in-class data and performance. If they adjusted their pricing model to better reflect actual usage, it would be close to perfect.
