Here’s an interesting product that you might want to investigate. Sigstr allows you to control the email signatures across a company where employees are using Office 365, Exchange, Gsuite, or other corporate email services. It enables banners to be included based on the contact, which can be segmented in any way. The system can even pick up banners for internal emails, perhaps to promote company information or events. Best of all, everything is under central control and looks to be really well integrated with analytics. It should be particularly compatible with Account Based Marketing (ABM), which continues to grow as a marketing strategy. There’s a short sales video explaining Sigstr here.
