It used to be said that you had to tell someone something five times for them to remember a piece of news. Then the number went to seven. After a while, it seemed like we were plastering news all over the church, hoping people would pick up the news somewhere. Now we realize that people are on information overload. They are so deluged with news and information that they don't pay attention to much of it. When you have used 7 or 8 communication techniques and people are complaining that they didn't know something or want you to begin calling to remind them before anything  happens, you know you have a problem. So, what do we do? 

              
 Right now, to convey information that people need, less is more. Pick 3 or 4 avenues of communication that you believe are the most easily accessible and make sure that people know what those are and that it is their responsibility to check them to know what is going on. We have to avoid reinforcing dependency by the techniques we choose. You also have to choose strategies that conform to the nature of your congregation. If they are tech savvy, slides before and after worship, midweek email notices, and notices in the bulletin may be enough. Verbal announcements need to be kept to a minimum because once you get past 3, people zone out (our rule is to verbally announce only the things that will affect at least 80% of the congregation) . If your congregation is not tech savvy, keep using mailings, posters, etc. Whatever your strategies, keep them limited to have maximum effect.
