Hi @lindaw,

Welcome to the Klaviyo Community!

Thank you for your question regarding Forms. Klaviyo has a fully built-in forms functionality known as Sign up forms. In addition to this, Klaviyo is also integrated with a number of leading form building applications such as Typeform, JustUno, Gatsby and many others.

Klaviyo’s native sign up forms can be embedded in your website directly without any development if you are using one of the supported integrations such as Shopify.

I’ll list a few key resources around forms:

Help Centre - Getting Started with Signup Forms

Academy Course - Build and customize your sign-up forms

Academy Course - Create Strategic Sign-up forms

I hope this helps! Let me know if you have any specific questions.

Thanks
David
