- Google Workspace
- Microsoft Exchange
The Problem
Your email signatures are wide open.
They carry your brand, and your legal disclaimer. Nobody can track every version.
- The template IT signed off
- Incorrect title
- A quote they liked
- Old banner
- Badge nobody approved
- Outdated logo
- Missing headshot
- Disclaimer dropped
Approved
After seven edits, none of them approved
A 1,000-person company sends roughly ten million emails a year. Every one can be a chance for something unapproved to go out.
Deploy once. Set the rules. Stop getting tickets.
It fits your mail flow.
Configure email signatures in Microsoft 365 or Google Workspace. Choose server-side, client-side, or both, to fit your security posture.
Information stays up to date
Your directory or HR system integrates with Opensense to keep titles, numbers, and departments current. Or upload a CSV to manage the fields yourself.
Choose what’s editable
Lock the fields that matter. Let people edit their own details, like pronouns and social links.

“We don’t ever have to worry about email signatures again.”
UWM 8,200 employees"The easiest thing for me is uploading users - it's so easy. If a user has an incorrect username, Opensense flags it, so I don't have to search for it manually. The user upload functionality is fantastic for the email signature portion.”

CMG Financial"We struggled with having to constantly update the plugin – which would not only impact our workload but would also impact the live signatures. We had double banners and other technical issues that we had to workaround. With Opensense, you put the tag in the signature, and it works seamlessly."

EDF Renewables“In my mind, the email signatures were there to enable our company to remain on-brand - but what I wasn't expecting was people to click and purchase. Since we’ve deployed the email ad campaigns, we’ve seen at least 17 purchases from our signature alone. That’s incredible.”
Kate R.Brand Director at Design PickleOpensense has become indispensable in our sales tech stack, helping us scale the team, boost productivity, elevate the customer experience, and reduce friction within the buyer's journey.
Esther F.VP of Sales Efficiency and Transformation at Five9“I was blown away. Not only could you track when a prospect opens an email but on what device, where they were in the world and on what email software. We could see their actions in real-time, get an instant replay video of how they interacted with attachments and videos, and whether they forwarded them. It’s incredibly powerful."
Jeff G.COO of C3 Metrics"The intuitive technology that Opensense uses to allow me to target those "hotter" prospects, and have a clear understanding of what they are looking for, so I can position my sales call accordingly. Review collected by and hosted on G2.com."
G2Mid-Market User in Transportation from G2 Review"Opensense provides a level of professionalism that comes with having a bonafide, fortified email signature where nothing can be misconstrued. You have all the power to fix or unfix an email signature for thousands of people with a click of a button. It's a game-changer, especially for a customer-facing industry like ours”
Sanford T.Senior Business Systems Analyst at CMG Mortgage, Inc.
FAQ
Frequently asked questions
Two ways, and you can run both together: server-side through an Exchange Online transport rule, or the Outlook add-in. With the add-in, mail stays inside Microsoft 365 end to end. Most IT teams finish the initial deployment in 45 minutes, and signatures then apply to every employee email regardless of device or client.
Yes, both, with deep integrations on each side. For Microsoft 365 that means Microsoft Entra ID, Exchange Online, and the M365 Integrated App marketplace. For Google Workspace it means Google Directory sync and the Gmail API. Centralized signature management and analytics work the same way in either. One platform, both environments.
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.
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. Opensense connects to HubSpot, Salesforce, and Marketo so your campaigns can be triggered by CRM data. The two work together, they don't compete.
Yes. Opensense is SOC 2 Type II certified and purpose-built for Microsoft 365 GCC High environments. We have many customers who have various certifications such as FedRAMP High, DFARS, ITAR, and CMMC. Email never leaves the Microsoft 365 environment with the Outlook add-in deployment. We are US Headquartered and US-based support is standard.
Yes, on every Outlook: Windows, Mac, Outlook on the web (OWA), and Outlook Mobile for iOS and Android. The Outlook add-in applies the same signature and banner wherever the message is written, so a reply from a phone matches one from a desk. (Server-side deployment through an Exchange Online transport rule is also available, with nothing to install on the device.)
Email signature management is the centralized control and deployment of professional email signatures across an organization. Opensense provides this solution for enterprise organizations, ensuring brand consistency, compliance with regulations, and enabling marketing opportunities through employee email communications.
Email signature campaigns are targeted banner ads that appear in employee email signatures. They leverage the daily flow of employee email to promote content, events, or offers with 4-7% click-through rates. Opensense enables this with a campaign management feature on the Opensense portal.
