Best Email Signature Software for Google Workspace
Opensense sets the email signature on every mailbox in your Google Workspace tenant from one place. Deploy through the Gmail API, through the Google Workspace Add-on, or run both. Signature content pulls from Google Directory, so when someone changes role the signature follows without anyone editing a template.

Deployment
Three ways to deploy in Google Workspace
Gmail API, Server-Side
Signatures are applied automatically through the Gmail API. Nothing for the sender to install, nothing for them to remember.
Google Workspace Add-on
People pick their signature inside Gmail while IT keeps central control of the templates. Run it on its own, or alongside the API deployment.
Google Directory Sync
Names, titles and contact details populate from Google Directory attributes. Group-based rules and SSO come with it, and signatures update when the directory record changes.
Live in 45 Minutes
Connect the tenant, authenticate with Google Directory, build a template, deploy. Legacy G Suite environments work the same way.
Opensense does not sign documents. If you are comparing DocuSign alternatives inside Google Workspace, this is the wrong product. This manages the signature block at the bottom of every email your company sends.

More than the signature block
The same deployment carries banner campaigns, engagement tracking and disclaimer rules. Banners average a 4 to 7% click rate. Teams that only want consistent signatures can ignore all of it.
Sales & Account Insights
Leverage granular engagement data and intent signals to nurture your prospect down the funnel. Multiple recipients on a thread? See how each engages with your emails.
IT & Brand Marketing
Effortlessly enforce signature standards across hundreds or thousands of employees, perfectly. Control everything from a single dashboard including compliance checks.
Growth & Event Marketing
With an average CTR of 4-7%, email ad banners promote your campaigns, events, and content to your most engaged audience.
Legal & Compliance
Optimize disclaimers and other compliance messaging with no heavy lifting including by sender or recipient country & language.
Scale
Company-wide, not mailbox by mailbox
One Template Set, Every Mailbox
One template set covers every mailbox. Rules target a Google Directory group, and new people are provisioned into the right signature without anyone adding them by hand.
Five Domains Included
Setup configures five additional domains for you. A company running several brands out of one tenant does not deploy five times.
Renders Where Gmail Runs
Signatures render on Gmail web, on Gmail for iOS and Android, and in third-party clients reading the same mailbox.
