There are plenty of good reasons to use ExSign for your email signatures
In large organizations it becomes difficult for an administrator to visit each employee's desk to set up new signatures. ExSign makes signature management easy with full control from one central location, so every email stays consistent and compliant, no matter which device it was sent from.
- Central Management: define rules once and let ExSign decide which signature or disclaimer to add to which email, instead of visiting every employee's desk
- Consistency: pre-defined rules ensure everyone in your company uses the same signature and disclaimer, with no distorted images, logos, fonts, or colors
- Most Devices Supported: server-side rules add professional signatures and disclaimers to emails sent from mobiles, tablets, Android, and iOS
- User profiles pulled directly from Active Directory, including custom attributes
- Legal disclaimers and compliance text applied automatically to every outgoing email

Always Highly Available
Always remain highly available with stamping from all mailbox servers. The ExSign Transport Agent is installed on all the Exchange mailbox servers in an Exchange environment, enabling stamping from each mailbox server.

Sent Items Update
See signatures and disclaimers in the sent items folder after emails have been sent out. Normally users cannot see signatures and disclaimers when emails are being dispatched and don't know how they look. With ExSign, experience how they look with the sent items update feature.
Time Based Rules
Define time intervals as conditions for your rules. These conditions will determine when to add signatures to emails sent by your organization. Time intervals can be specified in days, active hours, or date ranges.
Legal Disclaimers
Stay compliant with email disclaimers. Take advantage of centrally defined disclaimers to clearly communicate required notices, legal boundaries, and policy obligations to your recipients, especially across regulated industries.
vCards
Create stunning digital business cards that stand out and make sharing effortless. Embed QR codes directly in your email signatures so recipients can scan and connect instantly. Design from scratch or choose from a range of sleek, professionally crafted templates.
