BR

Bradley R.

IT Director

“It provides an intuitive platform for creating professional email campaigns, managing contact lists, and tracking campaign performance without a steep learning curve.”
SS

James G.

Senior Manager, Infrastructure Engineering

Pros

“It can be super granular, you can connect it to Facebook for creating custom audiences, it tracks everything from customer purchase frequency to when they are active on site, etc.”
Verified reviewer profile picture

Cody A.

President

“As a Klaviyo certified professional, I don't just see it as an email tool, but as a sophisticated engine for driving ROI. Whether it was setting up advanced influence-driven campaigns or optimizing high-volume e-commerce retail flows, the platform’s ability to handle intricate segmentation and real-time triggers has allowed me to deliver measurable growth for diverse international clients”

Marc G.

Digital and Marketing senior specialist

“The customization choices are amazing that enable us to design graphically appealing emails that present our hotel facilities beautifully without hiring a coder.”
PG

Patricia G.

Customer Service Lead

Cons

“You can't resize images within blocks, for example, and when you create a new block yourself, you can't copy and paste them into a new template or save them as a content block for reuse.”

Jill R.

Founder, Owner

“Some of the automation and advanced segmentation features are not as deep as some higher-end marketing platforms.”
BR

Bradley R.

IT Director

“The layout editor is pretty inflexible, or at least not a "friendly" user experience. While they have a lot of templates, there are definitely limitations on the creativity end.”
Verified reviewer profile picture

Jill R.

Founder, Owner

Cons

“The biggest con is that advanced features can be complex to navigate. But also the cost, as pricing plans can be expensive, especially for small businesses or anyone with limited email marketing budgets. And an important one for certian users is that while Klaviyo offers SMS marketing, its much more limited compared to dedicated SMS platforms.”
RO

Ricki O.

Owner

“It was an expensive product and we did not end up having enough sales to continue to use Klaviyo (more on us than the product for performing)”
SO

Shane O.

Operations

“The main downside is the pricing model based on total profiles, even if you’re not actively emailing those contacts.”
