We built Email Designer to work with the widest array of Email Clients. There are some limitations though; certain email clients only offer certain features. Below you will find a list of the most common limitations when sending emails to your clients.

Microsoft Outlook (Desktop version)

Unfortunately, Outlook is one of the most notorious email clients for rendering pretty emails; since 2007, its rendering engine runs on Word. As a result, a lot of design elements just do not render. The exception here is that Outlook on Mac actually uses Apple Safari’s rendering engine, so emails do not have these limitations.

  • Images have issues stretching

  • No rounded images or buttons

  • No gradients

  • No animated GIFs (Coming soon to Outlook 2019)

  • No custom fonts

  • No video support

  • Poor rendering of complex designs
