Updating distribution list
There are no hard and fast rules but in general, a distribution list can contain between 50-70 names and e-mail addresses.
You can also set up a distribution list of phone numbers in the Messages app for sending text messages to a group of people. Tap "Save" in the upper-right corner of the screen to add the email distribution list to your contacts data.
No association with any real company, organization, product, domain name, email address, logo, person, places, or events is intended or should be inferred.
Most email services and desktop applications include support for distribution lists, which are contact groups used to send messages to multiple people at the same time.
A prior can be elicited from the purely subjective assessment of an experienced expert.
An uninformative prior can be created to reflect a balance among outcomes when no information is available.
