I sent an email communication to three neighbors, apprising them of an upcoming event in our home so that the parking and traffic wouldn't be a surprise.
One wrote back "so sorry we can't make it!"
The second wrote "hope you have good weather and a wonderful time. Let's get together sometime!"
The third hasn't checked email today.
I couldn't ask for a better example of how a communication can land differently on different people.
Think about your messaging from multiple points of view, and ask others to read/edit before you communicate, especially if it is important.
Communicate messages in different formats - written and verbal - and send them multiple times, said in different ways to ensure your communication reaches and is understood by your audience.
