CodeTwo Email Signatures 365 is the first and only email signature management software with full Microsoft 365 certification: for the app, infrastructure, and Outlook add-in
CodeTwo’s cloud app infrastructure is regularly reviewed and pen-tested by Microsoft’s security specialists across three domains: application security, operational security, and data security & privacy. We remain the world’s only email signature service with full Microsoft 365 Certification – earned right at the program’s launch in 2022 and renewed ever since.
An Azure-based cloud service (SaaS) for managing email signatures, disclaimers, automatic replies, and branding for Microsoft 365 users. It’s the highest rated and most secure email signature software on the market, developed in compliance with ISO/IEC 27001 & 27018. Works with all email apps and devices.
The certification covers the SaaS application and its entire Azure infrastructure.
An Outlook add-in co-developed by CodeTwo and Microsoft. It automatically adds signatures as you type an email or lets you preview signatures that will be added in the cloud. Deployed centrally via the Microsoft admin center and Microsoft Marketplace. Works with all modern Outlook apps: desktop, mobile, and web.
The add-in is part of CodeTwo Email Signatures 365 but undergoes a separate certification process.
CodeTwo has consistently achieved M365 Certification since 2022, demonstrating their commitment to handling their customers’ data with care and security. We appreciate their diligence and look forward to the continued partnership with CodeTwo and the M365 App Compliance Program.
Getting the Microsoft 365 certification for our cloud app was a no-brainer. The entire process provided a great opportunity for CodeTwo to work with Microsoft’s top-notch security specialists and penetration testers, who shared a valuable insight and practical suggestions on how to further improve our security posture. Microsoft 365 Certification – along with our previous ISO 27001, 27018, and Cyber Essentials certifications – means that CodeTwo customers can be confident they use the most secure email signature solution on the market.

CodeTwo Email Signatures 365 thoughts »
CodeTwo Email Signatures 365 has all the functionality that we’re looking for and is the only solution verified with Microsoft, and so accordingly complies with all our compliance/security considerations. The other solutions that we looked at felt less professional and we were less confident that they would be able to handle the needs of a large organisation.
