distribution lists -

where can i find a list of all the distribution lists i have created

There’s not a way that I am aware of to filter the contacts for distribution lists.  A workaround might be to create a category called “distribution lists” and add that category to each list.  Then, you can use that category as a filter criteria.

One method is to sort the contacts by email address. A distribution list does not have an email address, so they should all be grouped together.
