Letsignit is a tool that is both simple and powerful for standardizing employees' email signatures and also treats the signature as a new media. It can be used as a low-cost acquisition channel. All of this integrated into Microsoft Office 365.

Carole Benichou

Director of Microsoft 365 Division

Before Letsignit with our old signatures, we couldn't add banners or do anything else. Everything was complicated. Although some things were possible, it took a lot of time for IT to create all the signatures.
