Hi @Maxwell,
Great question! Happy to help!
It all depends on your needs! While some find Klaviyo sufficient for their customer relationship management system, others utilize more tools than integrate with Klaviyo in an official CRM capacity. For instance, if you want to explore external CRM connections, we offer native integrations withs Salesforce CRM, Zendesk, and Gorgias. Alternatively, you can have a look at our Integrations Directory for third party CRM's that integrate with Klaviyo.
I’d check out these additionally Community threads on the topic as well to gain more insight!
Hope this helps and thanks for participating in the Community!
