"Klaviyo or who else?"
What do you like best about Klaviyo?

Klaviyo is one of, if not the top email marketing solutions out on the market right now. Their plans are reasonably priced and the product is great.

What do you dislike about Klaviyo?

Their SMS plans need some work to be comparable to their email solution. We recently decided to go with a different competitor for that reason (only for SMS).

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

Email marketing, audience segmentation, automation.

"Klaviyo is one of the best partners to have on your corner!"
What do you like best about Klaviyo?

Klaviyo is super simple to follow through on the website. The menus and the entire process are laid out clearly and efficiently. It pushes you to do better by showing tips and examples; it makes you want to click on more to learn; it helps you to look bigger and better; it develops a sense of 'marketing' instead of just emails. It is super easy to connect with other apps if needed and the support is always there!

What do you dislike about Klaviyo?

Not a lot of dislikes in the 2 years of us using Klaviyo.

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

It benefits us by assisting us to create beautiful marketing emails that create growth both in sales and in the brand side. It pushes to be better by developing itself.

"Klaviyo has been a game changer for us!"
What do you like best about Klaviyo?

Klaviyo has a robust campaign and automated flow process, along with great customer service, an attentive customer success team. The integrations with our tech stack flow seamlessly.

What do you dislike about Klaviyo?

It take a little bit of getting used to, and some research to truly customize. Sometimes flows can be a bit confusing depending on how in depth you wish to get with them

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

Klaviyo allows us to segment our customer base and send them emails at the right time, with the right content base on their specific behavior with our brand. The analytics behind it helps tremendously as well.

"Klaviyo has been great for us"
What do you like best about Klaviyo?

Klaviyo for email blows MailChimp and SendinBlue out of the water. The Automations, tagging, and template systems are the smoothest to use. Blocks helps with the look and feel of emails without being overly complex to use.

What do you dislike about Klaviyo?

Some parts of Klaviyo are not intuitive - for example, to change the color of bullet points, you have to change them in Styles, as opposed to the block editor itself. Sometimes, things don't save properly, so you must double-check to ensure things are as you intended before sending your campaign out.

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

Klaviyo solves dynamic tagging and segmenting of our customer base, as well as a relatively simple interface for creating email campaigns and flow automations. The sign-up forms are pretty decent too.
