I'm delighted to announce that the option to customize the preheader text (also known as preview text) of an email is now live and available in the 'subject' panel of any campaign or workflow email.

This option works on drag and drop, raw html, vero editable and rich text content types by adding a hidden line of text as the first element inside the body of the email. If you are using Raw HTML and Vero-editable content, please make sure you have removed any custom preheader text in your HTML code before using this option as using the Vero preheader option will not override it.

Thanks to everyone who voted on this feature.
