Without doubt, people like instant messaging. Messengers with media sharing, multiple group chats, video and voice calls, and even voice and video messages are a good replacement for inconvenient SMS messaging. This can be backed up by the fact that instant messaging giants like Viber, LINE, Telegram, and Slack have skyrocketed within the last years. According to Statista, the number of messaging app users was around 1.82 billion in 2017. This number is predicted to reach 2.48 billion by 2021.
Push notifications have become a necessary feature for many modern web and mobile applications since they inform users about important events, pull them back to a service, and encourage them to use it more.
