"Allows me to effectively categorize customers."
What do you like best about Klaviyo?

One key tool I enjoy using on klaviyo is its amazing segment feature which allows me to effectively categorize clients. This becomes very useful in unveiling eCommerce trends particularly with first-time buyers. The uses of integrating a loyalty program are almost invisible; it helps to improve our marketing strategies. Workflows are also a cinch to introduce, which is useful when you think about adding them for critical steps like abandon cart situations and welcome emails.

What do you dislike about Klaviyo?

But, the gif creating option on Klaviyo is a little restricted in my opinion. It would be also great if they could add more interesting moving objects that attract attention to demonstrate our products in email campaigns and thus make the companies who intend to improve their relationship with customers use the service.

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

Klaviyo is one of the companies that has been highly impactful in helping us resolve our gaps in communication with customers. It has greatly enhanced our outreach when effective, thereby increasing customer engagement.

"Best Option for Email Marketing and Automation"
What do you like best about Klaviyo?

We have never been able to segment and target so specifically until we started with KLAVIYO. Over half of our business income is directly attributed to our email and SMS marketing efforts. To say we rely on KLAVIYO is an understatement.

What do you dislike about Klaviyo?

The billing isn't the easiest to understand. They base it off of active profiles and usage. It seems like it would be one or the other.

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

The days of blasting out emails to your entire lists are over. KLAVIYO allows you to customize your marketing for the receipient and it makes an incredible difference in terms of conversions and postive interactions.

"Klaviyo helps us improve digital marketing and SMS automation"
What do you like best about Klaviyo?

I value the simplicity of creating an email with the flow editor. I like the simplicity with which you can update email corroborations and funnel emails, plus the good integration it has with Shopify. In order to make the distribution lists we have with us, and also the automation, expand and easier to manage, we can link Klaviyo with all the marketing tools we use in Shopify. Figuring out how to start a new campaign or where to find or develop customer information lists is pretty easy. It's complex and packed with features that make it possible for us to customize our marketing to the most current business circumstances. The automation of the mail distribution network is excellent. Klaviyo exhibits the usefulness of planning in order to target an audience in various time zones, such as missed carts, arrival streams, etc., as you reflect on the norms of your internet marketplace.

What do you dislike about Klaviyo?

It is feasible to have added a mobile responsive alternative when creating e-books, this would have been more helpful. We would like to incorporate loyalty points at the bottom of the page of personalized emails. PostScript integration could be improved. Most of the diversity of creativity can be seen quite limited in the email sender.

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

If you are adapting your email marketing strategy to a new platform, it won't take you long to learn how to use Klaviyo because its interface resembles those of other email marketing tools. To get beyond templates and generate marketing traffic, you don't need to have coding skills or have had a lot of experience in the area. It includes automation, fixed templates and a variety of layouts that is enough to distinguish your commerce. Klaviyo meticulously takes into account each of the organization's requirements, including first-class customization.
