Sigora review
A Microsoft 365-focused signature manager with cloud and high-availability self-hosted options.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Sigora is an email signature management platform for Microsoft 365 Commercial, GCC, and GCC High environments. It is designed for administrators who need centralized control over approved signatures, reusable content, directory-driven personalization, and organization-wide enforcement. Users can continue sending from their normal Microsoft 365 clients without Outlook add-ins or endpoint agents. The platform is available as BCM-managed cloud hosting or as a deployment inside customer-controlled infrastructure.
The published plans show two cloud options: SigoraOne Cloud Annual at $1.05 per user per month, billed annually, and SigoraOne Cloud Monthly at $1.17 per user per month, billed monthly. Both include fully managed hosting, all features, and volume discounts. The published starting rate is $0.69 per user per month with annual billing at 500 users, while the annual example for 100 users is $1.05 per user per month. A 90-day trial is available. Self-hosted options include Standard, 2-way HA, and 3-way HA, with all features included; the high-availability tiers provide active-active deployment choices.
Sigora’s strongest fit is for Microsoft 365 organizations that want server-side enforcement through Microsoft 365 mail flow, rather than relying on client-side tools. Administrators can create approved Base Templates and reusable Modules, assign signatures by user, group, or domain, map Microsoft directory attributes, preview results before rollout, and maintain published versions with administrative audit history. Microsoft Graph integration and multiple Microsoft 365 tenant management extend its administrative scope. Organizations centered on Microsoft 365 and requiring customer-controlled infrastructure should consider Sigora; teams needing broader verified mail-platform coverage or established campaign functionality should choose a product aligned with those requirements.
