Email Signature Management for Google Workspace & Gmail
Opensense is email signature management for every mailbox in your Google Workspace tenant: a Google Workspace signature manager, not a personal Gmail paste. Deploy through the Gmail API, through the Google Workspace Add-on, or run both. Signature fields pull from Google Directory, so when someone’s title or role changes the signature follows without mailbox-by-mailbox edits.

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. When the directory record changes, managed signatures update from those fields. That is directory-driven management, not a real-time sync claim.
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
See how each recipient engages on a thread. Use opens and clicks to prioritize follow-ups.
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 email signature management system covers every mailbox in the Google Workspace tenant. Buyers searching for a Google Workspace signature manager or a Gmail signature manager should recognize this page as the stack answer. The company-wide management hub across Microsoft 365 and Google Workspace stays on email signatures. Microsoft stack detail lives on Office 365 / Microsoft 365.
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.

Frequently asked questions
Does Opensense work with Gmail and Google Workspace?
Yes. Opensense is email signature management built for Gmail and Google Workspace. It integrates with Google Directory, the Gmail API, and the Google Workspace admin console. Gmail web, Gmail for iOS and Android, and third-party clients reading the same mailbox are supported. Buyers searching for a Google Workspace signature manager or a Gmail signature manager land here for the Google stack.
How does Opensense deploy email signatures in Gmail?
Three paths for Google Workspace and Gmail signature management: the Gmail API for automatic server-side deployment, the Google Workspace Add-on for in-client control with centralized templates, and Google Directory for field population and group rules. Choose one method or run more than one. Opensense does not sign documents; if you are comparing DocuSign alternatives inside Google Workspace, this is the wrong product.
Can Opensense integrate with Google Directory?
Yes. Native Google Directory integration supports provisioning, dynamic fields from directory attributes, group-based signature rules, and SSO. When employee attributes change in the directory, managed signatures update from those fields. This is directory-driven management, not a real-time sync claim.
Does Opensense work with Gmail on mobile devices?
Yes. Signatures render on Gmail web, Gmail for iOS, Gmail for Android, and third-party clients accessing the same mailbox. Brand stays consistent across those clients when the management platform is connected.
Can I use Opensense with both Gmail and G Suite?
Yes. G Suite is the old name for Google Workspace, and Gmail is the mail client inside it, so both describe the same environment. Legacy G Suite tenants deploy exactly like current ones: Gmail API, Google Workspace Add-on, or both. Signature content pulls from Google Directory either way.
How long does it take to set up Opensense for Gmail?
Most organizations finish first deploy of the Google Workspace signature manager in about 45 minutes: connect the Google Workspace tenant, authenticate with Google Directory, create the first template, and roll out. Implementation and creative-services guidance is available throughout.
Is Opensense a Google Workspace signature manager or just a template tool?

IT creates, assigns, and enforces signatures from one dashboard. The free email signature generator at https://www.opensense.com/email-signature-generator is for personal blocks. Opensense has a $500 per month platform minimum plus service plan. The broader management hub across Microsoft 365 and Google Workspace is https://www.opensense.com/email-signatures.
Is Opensense SOC 2 certified? Does Google Workspace get GCC High?
Yes, SOC 2 Type II annually (Security, Confidentiality, Availability). GCC High is a Microsoft 365 environment. Opensense is the only email signature platform inside Microsoft 365 GCC High; that is a different stack, not a Google government-cloud claim. Opensense is not a HIPAA product. Details: https://www.opensense.com/security and https://www.opensense.com/gcc-high-email-signatures.

How does Opensense compare to Exclaimer or CodeTwo for Google Workspace?
When shortlisting a Google Workspace or Gmail signature manager, buyers often weigh US-headquartered support, SOC 2 Type II, Gmail API plus Add-on paths, Google Directory sync, optional banners on Pipeline and Complete, and dual Microsoft 365 plus Google Workspace coverage. This page is not a ranked best-of and not a migration guide.
