“The scalability across devices and platforms is excellent. We always know that the person receiving our emails is getting the right signature and seeing a nice banner."Read case study
"We were already using an email signature solution but when it came time to renew, our team felt it might be best to find something better. We were firmly against plug-ins; we didn’t want our team to have to install or update anything; we definitely didn’t want to deal with any 3rd party software. This was the 2nd distinguishing factor for us choosing Opensense.”Read case study
“As a small marketing team of 4, we didn't have the bandwidth to chase down rogue email signatures. We'd have outdated links and campaigns, inconsistent branding, compromised logos; you name it. This was just not okay. Beyond that, we needed a flexible solution that could help us meet compliance standards across our team’s email, especially since we work with financial institutions, so data integrity with emails is critical.”Read case study
