The 1.8.3 version of HTML Email Signature for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This Mac app is a product of Element26, Inc. We recommend checking the downloaded files with any free antivirus. The software lies within Business Tools, more precisely Project Management.
From the developer:
Neither Microsoft Outlook 2011, 2016, 2019, nor 365 for Mac offer creation of email signatures from HTML. Only a rich-text editing box is provided, without the ability for more customization.
HTML Email Signature - Outlook enhances these capabilities by allowing customized creation of email signatures from HTML. Simply type in a name for your signature, add your HTML, and your signature is created! A button to preview the HTML is also available.
