Custom forms
By default, customers submit new requests via a simple open text field. Custom forms let you replace this with a structured intake form, collecting exactly the information your team needs upfront, like issue type, priority, or product area, so threads arrive in Plain ready to action.
Creating a custom form
Go to Help Center → Customer Inbox
Click into the Custom Form section
Add the fields you want customers to fill in
Click Save
Field types
When adding a field, choose from:
Dropdown: Let customers choose from predefined options. Good for issue type, product area, or request category
Text input: A short single-line field. Good for version number, account ID, or order reference
Text area: A longer freeform field. Good for a detailed description of the issue
Automating actions on submission
You can configure actions that are applied to the thread automatically the moment a customer submits the form:
Add assignee: Route the thread to a specific team member
Add label: Tag the thread with a relevant label
Add priority: Set the thread priority based on the request type
Add thread fields: Populate custom thread fields with values from the form
What your team sees
When a customer submits a form:
A new thread is created in Plain
A timeline entry shows the values the customer submitted
Any configured actions are applied to the thread automatically
