All email clients and mobile devices supported

CodeTwo Email Signatures 365 is a powerful solution that lets you centrally manage email signatures in any Office 365 (Microsoft 365) environment, regardless of what mail clients are used.

If our email signature software works in cloud (server-side) mode, it does not matter if you send emails via Outlook, Apple Mail, Thunderbird, Outlook on the web (OWA) or any other email client – signatures are added automatically by the CodeTwo service (directly in the cloud). Email clients are not even partly involved in the process. It's the same when messages are sent from mobile phones or tablets - email signatures look exactly and are inserted exactly as defined in the CodeTwo signature management app.

Email Signatures Office 365 all devices supported

With our application, you are always sure that users’ email signatures are correctly inserted, regardless of what device messages are sent from. And if you want your Microsoft 365 (Office 365) users to be able to choose their own signatures and decide where to place them in an email conversation, you can always switch to Outlook (client-side) or combo signature mode and give these users access to Outlook signatures.
