We have released the free Sociocs - Form plugin for Bubble. It can be used for any form you would like to add in your Bubble app (e.g. Contact Us form, Appointment Request form etc.)
This plugin enables form submission from your Bubble app. When your web app user submits the form, it shows up in your Sociocs Inbox, from where you can reply to the user, and continue the conversation.
