Collecting and exporting

Making it easy to collect addresses is what Mailbook does best. After signing up, the first step is to share your personal Mailbook invitation link with your friends and family. They land on an easy to understand interface that allows them to save their address to your address book.

Depending on your settings, you will get a notification by email about any newly added addresses. Your addresses are quickly accessible from your own dashboard. Each address can be edited, categorized by type (friend, family, work) or labeled (invited, declined, printed) which makes managing larger lists more easy.

All your Mailbook data can be exported as Excel or CSV file. These formats are supported by Windows, MacOS and Linux.

Print address labels

If you own a printer and buy label printing paper you can also easily print all addresses on labels using only Mailbook. Mailbook supports several label formats including the most commonly used Avery 5160 format. These labels are then stuck onto your envelopes.

If you don't want to DIY, you can have Mailbook ship your labels to your home with our address label delivery service.
