A signature is a reusable sender block (name, title, links) that templates render with the @Model.Cmf.RenderSignature(...) helper.
Email → Signatures.
What you can do here
Create, edit, and delete signatures in the signature editor, with one MJML/HTML block per language. Reference them from templates — the template editor's token picker lists them under Email Signatures — so a change here updates every email that uses it.
