About Signature Studio

Signature Studio is a personal and organizational email signature platform that turns one of the most overlooked parts of business communication into a managed, on-brand channel. It lets individuals design polished, email-client-safe signatures with logos, contact details, social links and brand colors, then install them into Gmail, Apple Mail, or iPhone and iPad using copy-paste or direct push tools.

For teams and companies, Signature Studio connects to Google Workspace to sync employee directories, import Send-As aliases, and deploy the right signature to every identity from a single admin console. Administrators can assign signatures by brand, domain, department, or individual, preview and approve changes, and audit every deployment. Marketing teams can layer temporary campaign banners beneath base signatures and safely restore them when a campaign ends, while IT keeps control of permissions, automation, and deployment health.

Signature Studio is built by Stageunderground, a company focused on making everyday business communication feel intentional and consistent. The platform is designed around the principle that companies should be able to govern their email identity without ever needing access to the contents of employee inboxes, using scoped Google Workspace permissions and keyless, Google-managed deployment rather than stored private keys.
