Overview
WiseStamp integrations are the tools used to apply email signatures across email platforms, devices, and CRMs.
Integrations support different deployment methods:
Client-side integrations – Apply signatures before sending
Server-side integration – Applies signatures after sending
WiseStamp integrations focus on centralized management, but also support manual installation for individual users.
Integrations can be combined to:
Provide signature preview on HTML-supported platforms
Ensure consistent signature coverage across all devices and platforms
Important: WiseStamp detects existing signatures and prevents duplicate signatures automatically.
To understand when signatures are applied, see WiseStamp Signature Deployment Methods.

Admins can share manual installation instructions with employees.
This allows users to install signatures individually across email platforms.
Process
Admin sends an invite email
User receives a link to setup instructions
User installs the signature manually
Tip: Manual installation is useful when centralized deployment is not required
For more information about manual installation, see Signature Deployment Methods.
