Before creating your first email signature in BulkSignature, review these important points:
Clean up existing signatures – Delete any previous email signatures in your Gmail Settings before using BulkSignature. The app installs signatures directly to Gmail Settings, so old signatures may cause confusion.
Disable other signature tools – If you're using other email signature management tools, disable them first to avoid conflicts.
Review your user list – Check the Company Data tab and remove any unwanted users before applying signatures, especially for Global Signatures which cannot be rolled back.
Reply/Forward setup – Due to Gmail API limitations, signatures for Reply/Forward emails must be enabled manually in Gmail Settings. However, if you had no previous signatures, Gmail will automatically apply BulkSignature templates for Reply/Forward use.
The 4 Signature Types
BulkSignature offers four signature types to fit different organizational needs. Each user can only have one active signature. When a user qualifies for multiple signature types, the system uses priority ranking to determine which one applies.
1. User-Specific Signature
Create a unique signature for individual users. Perfect for executives, sales reps, or anyone needing a personalized template.
When to use: Testing the tool, VIP employees, temporary campaigns for specific people.
2. Group Signature
Assign signatures to Google Groups. The signature automatically updates when members join or leave the group.
When to use: Cross-functional teams, project groups, role-based branding.
Note: Enable this feature in Settings → General Settings before use.
3. Organizational Unit Signature
Apply signatures based on your Google Workspace organizational structure. New members added to an OU automatically receive the correct signature.
When to use: Department-wide signatures (Sales, Marketing, Support, etc.).
4. Global Signature
Apply one signature template to everyone in your organization. This is the simplest option but comes with limitations.
When to use: Company-wide branding, small organizations, default fallback signature.
Important: Global Signatures cannot be rolled back. Once applied, users cannot be removed from Company Data directly. Contact support if you need to make changes after deployment.
