"Easy to use!"

4.5/5

What do you like best about Klaviyo?

Klaviyo is the most popular email tool in my opinion. Very easy to use, schedule, analyze, and so much reporting. Anyone can pick it up quickly bc it is so intuitive. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

I dont love the review integration. I recently switched to it bc the pricing and email component was great but it was NOT easy to set up. Feels like it is still in the early phase of it - not easy at all... Review collected by and hosted on G2.com.

"Pre-Sale Team went above and beyond."

5/5

What do you like best about Klaviyo?

We specifically want to thank Conor Ward and Shay Wenglin at Klaviyo for their support in the discovery process of their SMS platform.

They researched complex issues we were running into, advocated for us, and offered outstanding support at every turn. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

The cost of the platform is on the higher end. Review collected by and hosted on G2.com.

"Great experience with Klaviyo"

5/5

What do you like best about Klaviyo?

It provides easy-to-use templates for automations and campaigns. For a beginner, this would be the perfect free email marketing app anyone could consider. As long as your email lsit is below 500 emails per month. Review collected by and hosted on G2.com.

What do you dislike about Klaviyo?

The one thing I dislike about Klaviyo is that they have a monthly limit to the amount of emails a user can send per month. If they increased this or just got rid of it entirely, this would be a lot more benificial to faster growing companies who are not ready to pay for a business plan with Klaviyo yet. Review collected by and hosted on G2.com.

What problems is Klaviyo solving and how is that benefiting you?

A problem that my campaigns are dealing with currently, is overlapping and spamming. I realized recently that shopify already provides an automated campaign for emails that are sent to viewers who either abandon their cart, purchased an item, or made other important actions. Klaviyo was able to show me that there are drops in open rates, with certain emails only since they were basically sent twice by two different providers. This helped me fix a major problem with that.

"Great way to organize our email list"

5/5

What do you like best about Klaviyo?

We are able to make multiple segments from our lists to target differert customers depending on seasons and location. The reports are easy to read and understand. We have Klaviyo intergrated with Opensend and WooCommerece and it has functioned very well. Review collected by and hosted on G2.com.
