We'll create fresh WordPress site with Automate Slack Invite Gravityforms installed. You have 20 minutes to test the plugin after that site we'll be deleted.
With this plugin, you can send auto slack invitation via email to user who submitted a gravity form.
This plugin works with Gravity form only. Once you have created a gravity form and do required settings, this plugin will start working. Whenever new entries are submitted via gravity form, the respective user will receive an email with slack channel invitation link.
Example: Let say you have a slack team group, in which you want users to come up and chat/discuss. However, you don’t know to whom you want to invite.
So in this case, just create a gravity form with some fields and make it public on your website. Interested members will submit that form and they will automatically receives invitation email.
Note: Your Gravity Form must have an email field.
Development of this plugin is done on GitHub. You can report issues and suggest features.
