← All tagsIT admins are typically the people tasked with standardising email signatures across an organisation — often after a complaint from marketing, a compliance question from legal, or a new starter going days without a correct signature. The job involves choosing between architectural approaches, deploying the right tooling, and managing the ongoing maintenance without creating operational overhead.

Frequently asked questions
What are the two main architectural approaches to email signature management?
Server-side management routes outbound email through the vendor's cloud infrastructure, which appends the signature before delivery to the recipient. The email never displays the signature during composition. Add-in management injects the signature at the point of composition within Outlook itself, so the sender sees it before sending. Each has different implications for GDPR compliance, mobile device coverage, compose-time preview, and IT complexity.
What should I check before choosing an email signature management tool?
Key questions include: Does the tool support all email clients your organisation uses — Outlook on Windows, Mac, iOS, Android, and the web? Does it support the new Outlook for Windows (Office.js, not COM)? Does it process outbound email server-side, and if so, what are the GDPR implications? How are signatures deployed — via Centralised Deployment, MDM, or manual installation? Can templates be updated centrally without any user involvement? What happens to signatures when an employee leaves or changes role?
Can Microsoft 365's built-in tools manage email signatures for all employees?
Partially. Microsoft 365 mail flow rules can append a standard footer to all outbound email at the server level, and they're free. But they have significant limitations: signatures are appended after send so the sender never sees them in the compose window, image rendering is unreliable, and personalisation per user is limited. For consistent, visually correct signatures with compose-time preview, a third-party add-in tool is typically needed.
