To set up mail packs click on the Mail packs option from the Document library and then click the link to ‘ADD NEW MAIL PACK’. 

This will take you to the ‘ADD NEW MAIL PACK’ page.

The mail pack must be given a name, so that you can identify it. 

You can also add a description, where you can provide some more information about your mail pack. 

There is also a button named ‘Restrict use of the mail pack to the creator’, ticking this will mean that if there are multiple users on the account, only you will be able to use this document. 

The Product type defaults to A4 document, however you can use the drop down options to select a different product type. 

Click ‘Next’ to add documents to your mail pack.

You have a few options for adding files to your mail pack. You can upload a file from your computer, add a stored document from the library or add an existing mail pack. 

Full instructions for uploading documents are given in the article that covers “creating a mailing”.
