Opensense (formerly SenderGen) is an email signature management platform that centrally governs email signatures, banners, and digital business cards across Microsoft 365 and Google Workspace. It lets IT enforce on-brand, compliant signatures while marketing and sales teams run targeted campaigns, track engagement, and connect to CRM and marketing platforms such as Salesforce, HubSpot, Marketo, and Outreach. Opensense is SOC 2 Type II attested, operates under GDPR and CCPA, and is the only email signature platform running inside Microsoft 365 GCC High for ITAR, DFARS, CMMC and FedRAMP-driven tenants. It advertises a REST API for custom integrations and serves an llms.txt on both its marketing and documentation hosts, but publishes no developer portal, no API reference and no machine-readable specification; API keys are issued manually by an Opensense integration specialist.
