Frequently asked questions

How does Opensense deploy email signatures across my organization?

Opensense deploys via the Microsoft 365 Integrated App — a single admin manifest that IT pushes from the M365 admin portal. No mail routing changes, no DNS updates, no SPF record modifications. Most IT teams complete the initial deployment in under 15 minutes. Once deployed, signatures apply automatically to every employee email regardless of device or email client.

Does Opensense work with Microsoft 365 and Google Workspace?

Yes. Opensense is built primarily for Microsoft 365, with deep integration with Microsoft Entra ID, Exchange Online, and the M365 Integrated App marketplace. Google Workspace is also fully supported, including Google Directory sync, signature management, and analytics.

Can Marketing manage campaigns without involving IT for every change?

Yes — that is one of the core design decisions. IT deploys Opensense once and sets governance rules. From that point, Marketing manages banner campaigns, rotates creative, targets by CRM segment, and updates templates without filing an IT ticket for each change. IT controls the guardrails. Marketing operates within them.

How is Opensense different from HubSpot or Marketo?

HubSpot and Marketo send marketing emails to opted-in contact lists. Opensense activates the emails your employees are already sending — every prospect email, every customer reply, every partner communication. These are channels that don't require opt-in lists and cost nothing incremental per send. Opensense connects to HubSpot, Salesforce, and Marketo so your campaigns can be triggered by CRM data. The two work together.

Is Opensense certified for regulated environments?

Yes. Opensense is SOC 2 Type II certified and purpose-built for Microsoft 365 GCC High environments, including FedRAMP High, DFARS, ITAR, and CMMC-regulated organizations. Email never leaves the Microsoft 365 environment with the Outlook add-in deployment. US-based support is standard.
