Signaturky manages organization-wide email signatures across Google Workspace and Microsoft 365. Teams can create unlimited templates from professional designs or their own layouts, then customize logos, colors, fonts, and structure in the Signature Creator. Rules can assign signatures to departments, groups, organizational units, or individual users and enforce them continuously or daily. Microsoft 365 support covers Outlook Web App, desktop Outlook, and Outlook mobile apps. In Gmail, Signaturky can access and update user signatures, including aliases; that capability is Gmail-only. Installation must be domain-wide and cannot be limited to one user. Delegated admins can manage signatures without access to Settings or Billing. Google permissions include reading Workspace directories and writing Gmail settings to set signatures. Signaturky says customer data is stored in the European Union and that it needs no Google Drive permissions or access to private Drive files. The paid service offers a 14-day trial without a credit card, while displayed pricing is incomplete.
