Data Sovereign Email Signatures and Out-of-Office Replies

Unified Outlook branding everywhere – with zero external data exposure

Peer-Reviewable Core Agentless Sync No Mail Rerouting Sovereign Cloud Ready

🔗Put an End to Manually Managing Signatures and Out-of-Office Replies

Every signature and every away message represents your brand, supports ongoing campaigns, and ensures compliance with legal requirements.

Manual maintenance ties up resources, slows down updates, and increases the risk of errors and inconsistencies.

With Set-OutlookSignatures, IT handles the initial setup and Marketing manages the templates themselves. Staff don’t have to worry about a thing, and corporate data stays within systems that Security already trusts.

The free, open-source core and the Benefactor Circle add-on keep signatures and out-of-office replies always up to date at all times – from a central source across all Outlook editions and platforms: Windows, Mac, iOS, Android, Web, Classic Outlook, and New Outlook.
