Here is a good idea for helping your team better absorb the information sent out in important updates.
Instead of sending out lengthy emails containing every last detail regarding a new update, try condensing it into just a few key points.
This is a far better way to ensure your colleagues absorb the information.
If you still want them to have access to additional detail, you can include a “link to more information” for those who do want to read more into the subject.
You may have a fight on your hands with some people who think every one of their 1000 words is necessary, but once they see the wider benefit, it should all be fine.
