More about Mailbook
Mailbook online address book
Mailbook is a private online address book for people who want to collect, review, and reuse postal addresses without chasing everyone manually. Create a shareable address request, send the link to friends, family, customers, or colleagues, and let them fill in their own details.
Use Mailbook for holiday cards, wedding invitations, baby announcements, birthday lists, thank-you notes, customer mailings, or any moment where accurate postal addresses matter.
Incoming responses can be reviewed before they become saved contacts. Once saved, you can search your address book, update contact details, export addresses, or send letters and postcards directly from selected contacts.
Your Mailbook is private to your account. People who receive your address request do not need an account to submit their details, and address data is used for your address book and the mail you choose to send.
How it works in 1-2-3
- Create an address request for the occasion or contact list you want to build.
- Share the link through WhatsApp, email, SMS, or any channel your contacts already use.
- Review submitted addresses, save them to Mailbook, and use them for future letters and postcards.
