What variables are

Variables are placeholders like {UserFullName} or {CompanyLogo} that get replaced with real data when a signature is generated. They separate layout from content.

Why they matter

Variables mean one template serves everyone, and a single data change — a new area code, a rebrand — updates every signature that uses that variable.

Avoiding broken variables

Always preview with sample data and handle empty optional fields gracefully so a missing value never leaves a stray label or gap.

Frequently asked questions

Do I need to know code to use variables?
No — in KeyStamp you insert variables visually and see them resolve in the preview.
What happens if a variable has no value?
Good templates hide the line or fall back gracefully so nothing looks broken.
Can variables pull company-wide data?
Yes — company variables share one source so updates apply everywhere.
