I really would like to use Webflow for my portfolio site but the cost and what to do with my email hosting (which adds more cost; Google is NOT an option here) are problems I haven't been able to resolve yet. Adding Lottie certainly makes it more difficult to ignore as an option.
Try Zoho mail.
The way I look at it, Webflow is indeed more expensive than if you were to build a site from scratch. But if you compare it to more basic website builders the price is not that drastically different. You're paying for the tool too.
I'm not using Webflow at the moment, but the announcement video is awesome. Good job!
