We are especially fond of the database tracking and analytics that the software provides, second to none in terms of accuracy. We also really love that Klaviyo replaces a lot of plugins on your site with one single service as you are able to manage your email automations, campaigns, SMS messaging, pop ups and forms all from one place. This also reduces plugins to support as well as additional strain on your hosting because all of this is being managed out of a 3rd party service and not directly impacting your server resources.
