Before & after
Before
Email signature marketing lacked measurable impact, and IT teams spent excessive time manually managing signatures, opening the door to security risks.
After
Centrally branded email signatures generated 13 million impressions and 530,000 clickthroughs annually, resulting in a 4% clickthrough rate (CTR). They also influenced £6.1 million in revenue and saved 14,340 IT hours through automated updates.
CIS Security's challenge
CIS Security struggled with maintaining email branding consistency across their extensive workforce. Employees sent approximately 14,500 emails daily, but inconsistent email signatures posed both a security risk and a missed marketing opportunity.
The manual process of managing signatures for 2,900 employees across various devices was inefficient, vulnerable, and time-consuming.
Thanks to Exclaimer’s automated process, CIS Security not only streamlined their email signature management but also saw measurable results in marketing engagement and IT productivity.
