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

Letsignit stands out from the competition thanks to its strong AD integration and excellent customer support. Additionally, their feature set continues to evolve and become more robust.
