Context. The mental effort offered by a user to identify an important email from the email message is considered significant or impossible. A user must enter the e-mail application to determine what type of e-mail they have received. To let the user identify the type of email via smartphone notification, micro-interactions are utilized. De augmentatie in UX of de e-mail notificaties is dan getest met de modificaties gemaakt aan de micro-interacties. Objectives. This study explores the microinteractions in an email notification of a smartphone that requires the modification of micro-interactions. These modifications have been implemented based on the design principles and usability heuristics of the existing literature. With this implementation, the augmentation in user experience of the modified design is determined. Methods. On conducting a systematic literature review, the experimental design of micro-interactions is prototyped. These prototypes are subjected to user interaction by conducting interviews that include performing certain tasks on the prototype and obtaining the user's perspectives regarding usability with an SUS scale. The data collected has been analyzed to obtain data on user experience increase. Since this data is tested for statistical significance to prove the theory and the evidence reinforce each other. Results. User interviews resulted in 100% of the users being able to perform the tasks successfully during the interaction with the prototypes. The modified design or email notifications achieve job performance time that is much less than the time used by the user for the existing design. Meanwhile, The SUS score for the modified design of micro-interactions with the existing design achieved the best imaginable score which reflects the rise in user experience of the e-mail notifications on a smartphone. On analysis, these achieved scores showed their statistical significance of the claim of increase in UX.Conclusions. This study concludes the reduction in cognitive load in a smartphone's email notifications by effective application or design principles in microinteractions. Regardless of the increased number of email arrivals on a device, a smartphone user can now identify the important e-mails on a smartphone directly from the email notifications. Following the Google's Material Design Principles resulted in increased user experience of e-mail notifications on a smartphone. However,
