How to Send an Error Message to a User

I like to see ideally it would be an icon that is associated with what happened so if an email is sent maybe a little mail icon if Something is saved to the database maybe a big check beside it If something has gone wrong Like something or something is has gone wrong and it will retry in however many seconds Maybe like a red with a clock on it Just enough information to sort of tell me what's going on but at a very basic in X or a checkmark telling me Good or not. Yeah, and I don't mind emoji for these things either personally No, me neither. But I do tend to like like a green Or I eat like a checkmark for good or a smile
