# Version History

Every save increments the template's version number, and the current version is shown on the template list and in preview — so you always know which revision is the one sending.

Questions

## Common questions, straight answers.

When does the version number change?

On every save of an existing template. A new template starts at version 1; each update increments it automatically.

Can I roll back to a previous version?

Not with one click today. PostFrame keeps the version number, not the previous body, so duplicate a template before a large edit if you want a safe copy to return to.

Where do I see a template's version?

On the templates list, as a v2, v3 badge once a template has been edited, and in the preview dialog next to the template name.
