Platform

The complete email signature platform

Design and test a signature, deploy it through your own mail platform, and see who has it.

Design and test

One approved design, previewed with employee details and render-tested before anyone receives it.

  • Signature Templates

    Every plan

    Brand-ready designs with real render previews; set your color, font and logo once.

    Browse the template library →
  • Signature Editor

    Live preview with employee details, fields from your directory, or your own HTML with merge fields.

  • Render Testing

    An Outlook compatibility check, plus Gmail, Apple Mail and phone previews, before you publish.

  • Approval Workflows

    An approver signs off before a campaign, A/B test or new signature goes live, on every plan. On Enterprise you can also lock a signature, or just its footer, so it cannot be edited in the console.

Deploy

Your own mail platform applies the signature. By default Bantusign is never in your mail path.

  • Google Workspace

    Starter and above

    Written to each Gmail mailbox through the Gmail API, for new messages in Gmail on the web; edits arrive within minutes.

  • Outlook Add-in

    Every plan

    Inserts the approved signature when someone starts a message; installed by an admin.

  • Exchange transport rule

    Growth and above

    Appends the signature to outbound mail from any device, checked and repaired every 6 hours. Setup is guided.

  • Shared Mailboxes

    Get their own signature from the add-in and never use a seat. With the Exchange connection (Growth and above), pick them from the shared mailboxes Exchange Online reports.

  • Gmail Add-on

    Inserts the approved signature from the compose window.

See who is covered

See who is covered and what needs attention: each person’s status, the evidence behind it and the latest check.

  • Signature Coverage

    Confirmed, Inferred, Pending, Drifted or Not covered, with the evidence and when it was checked. Inferred is never rounded up to Confirmed. Troubleshoot lists the checks behind a status and changes nothing.

  • Drift Detection

    Gmail mailboxes read back every 24 hours, the Exchange rule every 6 hours (Growth and above). Admins are alerted once when verification stops, and the alert clears when it is fixed.

  • Test Email

    A person sends one test email from the Me page, from their own mailbox to a one-time address Bantusign owns. It proves their signature on that message; everyone else stays Inferred.

  • Analytics and Signature Health

    Growth and above

    Clicks, impressions counted as image loads, A/B results, brand consistency and link monitoring. No IP address is stored.

  • Scheduled Reports

    Growth and above

    Coverage and analytics reports by email and as PDF; partners schedule PDF and CSV reports for their clients.

Administer

People, access and billing in one place, with the controls IT expects on every plan.

  • Directory Sync

    Hourly by default from Entra ID, Google Workspace, BambooHR, Workday, ServiceNow or a CSV, with protection against accidental bulk removals. SCIM provisioning on Enterprise.

  • Organization Hierarchy

    Assign designs by department, job-title rule or person, across subsidiaries.

  • Single Sign-On and Audit Log

    Every plan

    SAML 2.0 and OpenID Connect with enforcement; every change logged and kept seven years by default.

  • API and Webhooks

    Every plan

    API keys, a read-only REST API and signed outbound webhooks.

  • Seat Billing

    Per seat with no minimum; alias mailboxes are never billed, and a downgrade keeps everything you made.
