In 2016, we committed ourselves to a strict GDPR framework. This required some major structural changes within Letsignit at all levels. We passed an important milestone in 2022: ISO 27001 & ISO 27018 certifications. That means we offer all Letsignit customers with the highest standard of security, from implementation to day-to-day usage.

Don’t take our word for it.
More than 1 million people trust Letsignit with every email they send.

We needed a solution that meets the level of security required by a bank and integrates directly into Outlook. Letsignit meets this dual requirement, especially since obtaining its ISO 27001 & ISO 27018 certifications!

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.
