Failing to reply within a day, leaving messages on "read" and bombarding people with your thoughts are the worst messaging etiquette mistakes, a new guide by Debrett's has ruled.
The renowned etiquette company has launched a new manual in collaboration with Facebook on how to properly use messaging apps, amid a trend towards increasingly using emoticons and memes instead of formal English words.
Long and rambling stories, oversharing other people's information and ignoring messages are among the most hated habits that persist on online messaging apps, the guide states.
People dislike when their messages are left unanswered in group chats and will check to see if people have seen and ignored their responses by watching for a blue tick, which means "read", Debrett's says.
Simple tasks, such as saying goodbye, acknowledging someone's message and avoiding the use of sarcasm or irony can make the difference between a good conversation and one where the sender is ignored.
