Testimonials

What are others saying about Opensense?

Read why the world's most advanced marketing & sales teams use Opensense as their preferred email signature, marketing, sales, and compliance solution.

“Overall, we are delighted we made the switch. No matter how big our team continues to grow, managing our team’s signatures will not be an issue for us - in fact, they look even better than the ones we had before.”

Brent SchapmanSystems Administrator at UWM

“Our current system was good, but it wasn’t the best. That’s when we decided it was a good opportunity to re-evaluate our needs and find a solution that exceeds our needs rather than just continue with the vendor we were with.”

Chuck VanderbergOffice 365 Engineer at American Cancer Society

“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.”

Christine KellyMarketing Technology and Automation Manager at Cvent

“We did not have a good experience with the previous solution - overall, the support was not there, and the system was lacking. We explored other vendors and ruled them out pretty quickly. Opensense just checked all the boxes.”

Mitch WoodsSenior Demand-Gen Specialist at Baker Hill

“For us, a major selling point was that I didn’t have to set up licenses and install one by one and instead do it at the server level.”

Rosa YooABM Marketing Manager at Snowflake

“The main differentiator between Templafy and Opensense for us was that we are a Google Workspace company, and Opensense already had an integration with Google Workspace and proven case studies.”

Lisa BorgSenior Vice President of Marketing at Akumin

“Managing email signatures before Opensense was like navigating the Wild West. We resorted to the old-school ‘here’s the template, grab it from SharePoint, and hope-for-the-best’ approach. It was a chaotic and uncontrolled signature landscape.”

Tom CelikCorporate Website Manager at ARCOS
