I'm in the same boat here. I'd LOVE to bring all the apps/programs that I use under Squarespace, for instance, switching from Convertkit to email campaigns. But I have forms on my site that are not newsletter forms, and I can't find a way to connect my existing forms to an automated message in Email Campaigns. I came to this Forum to see if there's a work around but if not, I won't be upgrading my Squarespace account with any of their supplemental services, all of which ideally sound great, but are still half-baked.
