Very quick to respond and fix any issues. The form has everything that I need and I have been very happy with their service!
5 stars! Customer support is really professional and patient. The contact form builder plugin is easy to use with an excellent experience. Highly recommended for Shopify stores.
This is a great app. Rosie is also great, has helped me very fast on multiple occasions.
Using the free version for now, so far so good. Taylor was very helpful showing me how to build the form I needed.
A powerful product with strong technical support. I hope for more customization options and improvements to the "Required to login" interaction—even if it means upgrading the plan, haha.

The fastest check: search "import from Checkout Blocks & Customizer" in each app's help center. AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.
