What reviewers say
Centralized Signature Management That Just Works for the organization
“A central place to handle or manage signatures for the organization.”
Effortless Mobile Signature Management
“I like the addition of mobile email signatures and the ease of setting up a user with an email signature. With Signature 365, we can set up a distribution group and link this to the signature manager. Simply adding a user to this group generates a signature, making the task quick”
Centralised Control & Consistency
“Signature 365 provides a single dashboard for managing all email signatures, ensuring consistent branding and compliance (e.g., legal disclaimers) across Outlook clients on desktop, mobile, and web.”
