Frequently asked questions

01
How does email signature management software deploy across Microsoft 365?

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.

02
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 fully supported, including Google Directory sync, centralized signature management, and analytics. One platform, both environments.

03
Who controls email signatures — IT or Marketing?

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

04
How is Opensense different from email marketing software like HubSpot or Marketo?

HubSpot and Marketo send marketing emails to opted-in contact lists. Opensense governs the emails your employees are already sending — every prospect reply, every customer email, every partner communication. These are channels that require no 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, they don't compete.

05
Is Opensense email signature software compliant for regulated industries?

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.
