Speed up mass mailings by printing to address label sheets, envelopes or label rolls.
Lists can be sorted on first/last names, manually, birthday and zip/post code.
The zip/post code sort lets you target your mailings to specific neighbourhoods/locations. Also, this can be especially helpful in the USA allowing you to get the lowest possible postal rates for bulk mail.
The birthday sort allows you to create a really useful birthday list where you can see at a glance which birthdays are coming up. 
Compatible with the very popular iOS AddressLabels, on the App Store since 2010.
Uses Cloud syncing (macOS 10.15 and later)
Use your lists year after year.
Personalize your labels/envelopes with an image (in-app or from disk), different text colours and fonts.
Create Return Address labels either from an address in Contacts or by manual entry.
Easily print multiple labels for anyone in your list.
Record the no. of cards written, mailed, hand-delivered or sent as eCards.
Number of stamps (including international) required displayed.
Import the names from your Contacts, spreadsheet csv files or type manually.
Imported names can use an alias on the labels e.g. you can import “Mr John Smith”, but display and print “John and Mary”, or “The Smith Family” etc.  Also, you can use the person's nickname.
Record when a card/letter has been received and view the history of cards sent/received - maybe stop sending to someone who hasn't replied for a while!
Store extra information e.g. names of children, type of card person prefers etc.
The labels can be used for name and addresses obviously, but also for phone numbers and email addresses.
The label data has the "name" on the first line, and the "address" on the following lines. Of course, these do not have to be people's names and addresses. For example, you might just use the "Name" field for Storage Jar labels.
For label sheets, select from template descriptions or Avery code numbers.
