Signature Templates

Professional designs, ready to deploy

Choose from distinct layouts — corporate, executive, minimal, creative or campaign-ready. Deploy to Gmail through the Gmail API, or to Microsoft 365 through the Outlook add-in or an Exchange rule (Growth and above).

What sets it apart

Less signature work, and nothing in your mail path

Kept current by your directory

A new hire or a new title updates the signature without anyone editing it.

Hourly by default from Entra ID, Google Workspace, BambooHR, Workday, ServiceNow or a CSV.

Schedule campaigns across team signatures

Schedule a banner with a start and end date, and optional approval before it goes live.

Gmail, Outlook add-in and Exchange rule signatures. Click analytics store no IP address.

Out of your mail path

Gmail, the Outlook add-in and the Exchange rule apply the signature themselves, so your email is never routed through Bantusign.

Optional Cloud signatures routes selected outgoing mail through our relay, and is off unless your administrator sets it up.

Questions before you start

What is email signature management?

Email signature management means designing, deploying and keeping current the signature at the bottom of every employee’s email from one place, instead of each person editing their own. Bantusign is not a document e-signature product like DocuSign: it manages the signature block on your outgoing email.

Does Bantusign work with Microsoft 365?

Yes. The Outlook add-in, installed by an admin, inserts the approved signature into new messages on every plan. Growth and above can add an Exchange transport rule that appends it to outbound mail from any device.

Does Bantusign support Google Workspace?

Yes. Bantusign writes each employee’s signature into their Gmail settings through the Gmail API once a Google super admin grants domain-wide delegation. Edits and publishes reach mailboxes within minutes.

Does Bantusign read or route company email?

Not unless you turn it on. The Gmail API, the Outlook add-in and the Exchange rule never route your email, and our servers never receive its content. Optional Cloud signatures is the one exception: your administrator turns it on, and only the outgoing mail your rule selects passes through our relay, which adds the signature, stores nothing and returns it to your Exchange Online or Google Workspace to send.

Is a credit card required, or a minimum number of users?

Neither. New accounts start with a 14-day free trial of the plan chosen at sign-up with no payment card, and pricing is per seat with no seat minimum. Alias mailboxes are never billed.
