This article introduces a preview text hack for optimizing the preview text in emails. The preview text in the inbox can be as long as the subject line, but it can be challenging to optimize because email clients fill the available space with text, potentially causing truncation or displaying non-optimized content. The preview text hack involves adding a chain of zero-width non-joiners (͏ and ) and non-breaking spaces ( ) after the desired preview text to create white space and prevent distracting text or characters from being pulled into the envelope content. The hack may not work in all cases, as email clients constantly change, but it can be considered a progressive enhancement for a better subscriber experience. Different variations of the hack are suggested, and testing is recommended to find the most effective implementation. The article provides examples of where to insert the code for the hack and highlights the importance of testing preview text and emails overall. The hack has been used successfully by brands, and there haven’t been negative impacts on deliverability. It is encouraged to take control of preview text and give the hack a try to improve email performance.
