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.

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.

Letsignit makes it easy to create campaigns and manage contact groups. Its link with Office 365 simplifies internal implementation and allows for tracking of user usage. The separation of signature and campaign creation enables fast updates, even with multiple entities.
