When it comes to spreading an important message or piece of information, there are several phrases that can be used instead of "spread the word". For example, you could say "get the word out", "share the news", or "disseminate the information". Other possible synonyms include "broadcast the message", "circulate the word", and "propagate the idea". You could also use more specific phrases depending on the situation, such as "promote the event" or "publicize the product launch". No matter which phrase you choose, the goal is always the same - to let as many people know about a particular message or piece of information as possible.
