Exported sites will not work with Webflow Forms. Any submissions to forms will not be sent to the forms tab of the project settings, and will not be processed as a submission. Forms on exported sites must be connected with a custom action and a third party form integration in order to function.
Forms will only send an email to the email address in Send form submissions to: field located in the Forms tab of your project settings. If you need an auto-responder to be sent to the user who fills out a form, you will need to use a third party form integration.
On hosted sites (e.g., sites with an active site plan), you'll be charged $1 per 100 extra submissions over the limit on your next monthly invoice. On unhosted sites (i.e., sites without an active site plan), forms will not be submitted after the limit is reached.
By default spam filtering is enabled for all sites, existing and new.
Spam filtering is enabled at a site level, you cannot disable the filter on some forms within one project and not others, however, you can have some of your projects with spam filtering enabled and some projects with the spam filtering disabled. You can disable the spam filter in Site Settings > Forms > Spam filtering, this gives you full control over if you have the spam filter applied to your sites forms
