Where Marketing and IT finally agree

1
IT defines once. Marketing operates daily.
IT sets brand standards, group permissions, and audit logs at setup. Marketing publishes campaigns, targets audiences, and runs A/B tests without waiting for IT..
2
One Microsoft 365 stack. Two teams served.
IT inherits Microsoft 365 platform security, conditional access, and Defender. Marketing gets a native Outlook experience: the signature renders the way it was designed, every time.
3
Used every day. Measured every week.
IT sees the platform actually adopted across team. Marketing sees click rates, A/B test results, and campaign performance. The signature becomes a measurable channel, not a static asset.
4
One number to call when it matters
Direct chat, dedicated CSM, response under 48 hours, and a 16-expert customer success team.

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.

I love the ability to change signatures and ad campaigns with just a click thanks to Letsignit. We used to have issues with uniformity, but this is no longer a concern for us.

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.
