It's been great. I had one experience with customer support where I felt the person wasn't going to pass on valid feedback (open rates of the first email cut by half due to < 2 hour wait with FB sync). But other interactions with support were great and I also was able to connect with their product manager who promised to look into it. I felt they're a young and flexible team. Also laser focused on email and what email marketers need.

If you want flexibility in segmenting your drips (or flows as they call it) then you need to use Klaviyo. We were using Mailchimp and kept finding areas that made it time consuming, confusing, or just not built to have a flexible drip campaign where contacts receive emails based on rules. For example you can easily create a series of emails that are only sent to contacts that meet a specific criteria and do it all within one drip through a "workflow" like drag and drop builder. You can also sync up to your facebook leads and save money on Zapier which is what you need to use if with Mailchimp.

While Zapier immediately pulls in leads from Facebook, Klaviyo only syncs every 2 hours. A lead getting a welcome email right away is SUPER important, but this means they don't hear from us for some time and it's negatively impacted our first email open rates -- almost cut it in half.

I love the ease of use, likely because we've used it for so long and I'm so familiar with the platform. When they do make updates, it's not too much at once in the way many companies go about updating. The email editor is simple, the ability to a/b test is as well. Overall great functionality.

I think the native content boxes can be more customizable although they are improving slowly. I'd love to be able to set the font sizes on mobile to be a percentage of the size on desktop instead of choosing multiple font sizes. They used to have amazing support, it's nowhere near where it used to be.

Being a developer myself, I informed the Klaviyo team of the deprecated code errors their plugin was displaying on peoples websites, and to the fact that their plugin slowed customers websites down drastically. The reply I received a couple of days later was: "Unfortunately we do not update our plugin very often - but our team will get around to it eventually." This was 2 years ago, and the plugin still has not been corrected. So it still produces errors, and still slows peoples websites down.

Klaviyo is extremely easy to setup, especially compared to its competitors. You have the freedom to link Klaviyo with your Wordpress/WooCommerce website seamlessly. Everything can be automated! Such as emails after order received, emails after payment received, multiple emails after certain time duration's for things like newsletter subscriptions and a lot more options are available to include users website Wishlists, items they left in their shopping carts to remind them, and all emails are fully customisation using the Klaviyo's inbuilt email form designer. You can also arrange customer lists, newsletter subscription user lists, and any other lists you may require. The possibilities are endless!

Using Klaviyo on your Wordpress website as subscription signup form slows your website down, a lot! Although unnoticeable to customers surfing your site, Klaviyo also throws a few error on your page as it uses deprecated (out-dated) code. If the Klaviyo form builder doesn't produce the look/type of form you require, then you must build the form yourself by coding direct on your website (Which beats the point of having a form builder). The Klaviyo plugin does not update, and never announces that there is a new version. You must remove the plugin from your website, manually download the latest version from their website, and then upload/install/activate the new plugin. There is no option to change languages or string translations of forms, form input boxes, or form buttons. And these translations cannot be picked up in Wordpress plugins such as Lingotek or Polylang. The same applies to the confirmation pages after the user submits the forms.

We’ve used klaviyo for years, it worked great with Magento and even better with Shopify. The flows are very powerful and everything is so easy to use. They keep releasing updates too so it’s it’s very good value for money.

Definitely the drag and drop email template builder and the flexibility it has for mobile. The sign up forms are just as easy to make. The whole platform is very user friendly.

The sms campaigns are pricey and you’re very limited on character count. Watch out for your sms usage as if you go over you’ll be auto upgraded to the next payment tier.
