Built for every team that manages email at scale

Businesses & Organizations

Deploy a consistent, brand-approved signature across Microsoft 365 and Google Workspace without routing your email through a third-party server. Gmail signatures are written through the Gmail API; Microsoft 365 uses the Outlook add-in on every plan, or an Exchange rule on Growth and above.

• Centrally managed templates with logo and legal disclaimer
• Employee data synced from your directory every hour by default, with edits reaching Gmail mailboxes within minutes
• Per-employee coverage status with the evidence behind it, so you can see what is Confirmed and what is only Inferred
• Daily drift checks alert you when a Gmail signature is changed or an Exchange rule is edited
• Optional approval before a campaign or A/B test goes live
• Single sign-on and an audit log on every plan

Enterprise

Governance for large and multi-entity organizations: subsidiaries, delegated access, SCIM provisioning, and Microsoft 365 deployment through an Exchange transport rule that Bantusign checks and repairs.

• Exchange transport-rule deployment for Microsoft 365: applied to outbound mail, re-checked every 6 hours, and repaired automatically with a notice to your admins
• SCIM 2.0 user provisioning and deprovisioning with Okta, Microsoft Entra ID or any SCIM-compliant identity provider
• SAML / OIDC single sign-on with enforcement, included on every plan
• Organization hierarchy and subsidiaries, with department-level template assignment
• Full audit log of every change, kept for seven years by default
• Data retention policies and domain verification

MSPs & Managed Service Providers

Manage all your client organizations from one partner portal. Each client keeps its own isolated workspace, and you switch between them without signing in again.

• One login, no cap on client workspaces
• Switch clients and land on the page you need
• Per-client coverage evidence and a portfolio view of every client, with an exceptions queue and bulk sync, drift and connection checks
• A verification level for every client (Confirmed, Mixed or Inferred, never rounded up), the latest delivery-check result and the Exchange rule's health, a Needs verification attention filter, and a failed check as its own entry in the exceptions queue
• Scheduled PDF and CSV partner reports for your clients
• Delegated access: give team members the Viewer, Editor or Admin role on specific clients, with a default 90-day expiry (optional: 30 days, 1 year or never) that you can renew, revocable at any time by you or the client, and fully audited
• Clients can see and revoke partner access themselves, and you can link an existing organization as a client
• A Partner Library of master signatures: apply a master to the clients you choose, see what changes for each client before anything is applied, and let each client override only a few fields (disclaimer, accent colour, social links, website and logo placement) while its own logo, colours and address stay its own. If a version turns out to be wrong, you can revert the master to an earlier version, and a client can revert its own copy to the previous version
• Client sign-off: a client can require its own admins to approve a signature or campaign you publish in its workspace, or a master update; your staff cannot approve it, the request expires if nobody answers, and you see what is waiting in the portfolio
• Partner-pays billing on one subscription with a per-client invoice breakdown, no seat minimum, and not-for-resale seats for your own team agreed with us
• White-label client emails, PDF reports and support address, with your logo and a Powered by switch

IT Teams

Connect your directory, then let scheduled checks do the watching. Bantusign works with your existing directory infrastructure and surfaces alerts with links to the fix, with no per-user configuration.

• Microsoft 365 and Google Workspace directory sync, hourly by default and configurable
• Guided Exchange transport-rule setup on Growth and above: a Microsoft admin approves access and assigns the Exchange Administrator role, Bantusign checks first and creates the rule once it detects the role, and can roll it back; the rule is read back every 6 hours
• Register shared mailboxes, typed or found in Exchange Online (Growth and above), so the Outlook add-in applies the right signature when someone sends from them; they never use a seat
• Sync error alerts with links straight to the fix
• SCIM provisioning applies changes as your identity provider sends them (Enterprise); HR systems sync on a schedule you set
• A mass-departure guard and a seat-approval step on directory sync
• A render test before every publish to avoid visual surprises
• API keys and a read-only REST API

Marketing & Brand Teams

Turn every employee email into a brand touchpoint. Design once, deploy to every employee, and run time-boxed campaigns without involving IT for each change.

• A brand kit (colour, font family and logo) plus a library of designs with layout variants
• Import your own HTML signature with merge-field mapping
• Signature banner campaigns with scheduled start and end dates on Gmail and Outlook add-in signatures
• Click-through analytics per campaign and department, with impressions counted as image loads (Growth)
• Privacy-first click tracking: no IP address or user agent is stored
• Brand consistency score that checks your live templates against your brand kit (Growth)
• Broken-link monitoring for logos, banners and campaign links (Growth)
• Department-level template differentiation (Sales vs Legal vs Support)
