Hi @vitbarreto
Thanks for sharing your question with us! Happy to hear you’re taking advantage of the Growth Podcast!
While Klaviyo does have a lot of data available especially through our Profiles tab, unfortunately, Klaviyo cannot perform most CRM actions alone or offer a full CRM solution as other integrations would. As an ESP that allows you to send targeted email campaigns and Flows, Klaviyo does not track inbound emails or allow you to set up follow up reminders as a classic CRM would. In case you want to explore other CRM integrations you might not have discovered before, here’s how you can check out Klaviyo Partner Options.
In mind to the insertion of tags, depending on your integration, you can, for instance, use tags in Shopify to filter customer actions or behaviors. Shopify's customer tags are assigned as custom properties to the Klaviyo profile of each customer who is synced into Klaviyo through Shopify.
Klaviyo will create a single "Shopify Tags" property, which is stored as a list data type.This is because when these tags are used, there are often several tags applied to the same customer. The difference between lists and strings is that the string data type is used to collect a single word or single phrase (i.e. any plain text), while the list data type is used to collect an array of words/phrases, where each item in the array can be identified individually. When using the property in a segment or filter, you can include as many available tags as you'd like using multiple conditions.
