Email Signature Migration

Email signature migration is the process of moving from one signature management platform to another. Common reasons for migration include cost (moving to a lower-priced platform at scale), feature gaps (current platform missing capabilities like directory sync, analytics, or compliance features), service issues (deployment reliability, support quality), or platform end-of-life. The migration involves several steps: template re-creation in the new platform (signatures are not directly portable between platforms because of proprietary template formats), directory reconnection (re-authorizing the Microsoft Graph or Google Directory API access on the new platform), deployment cutover (switching the Exchange transport rule, Outlook add-in, or Google Workspace routing rule from old to new), and decommissioning the old platform (revoking permissions, exporting historical analytics, canceling the contract). Best practice is to run both platforms in parallel for a brief period to validate the new platform before fully cutting over. Migration timelines typically span 2-6 weeks for organizations of 50-500 employees, depending on template complexity and number of campaigns to recreate.
