Step-by-step: setting your job title and signature
Sign into the Case Management system with your email address.
Open "My Organisation" from the navigation.
You'll land on the Users tab by default.
Find the user in the table (you'll see "(you)" next to your own row).
Click the three-dot (⋯) menu on that row and choose Edit.
In the Edit User dialog, fill in:
Job title — single-line text field
Email/SMS signature — a plain text box (up to 2,000 characters)
Click Save.
Where it's used: when you compose a message to a client, the body is pre-filled with "Hello ," plus your name and your saved signature. If no signature is set, service emails fall back to "Best wishes, , , ".
