"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.”

“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 We'd have outdated links and campaigns, inconsistent branding, compromised logos; you name it.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.”
