Postable alternatives depend on what you want the address book to do next.
Postable is a strong free address-book and card-sending product. Other tools make sense when your priority is event guest data, general contact management, labels, or a mailing address that the recipient can maintain over time.

HOW IT WORKS
Ask once. Keep the result useful.
1
Choose your primary job
Cards, event guest management, labels, general contacts, or ongoing address freshness each point to a different product.
2
Check portability
Import and export matter if the list needs to move to printers, spreadsheets, or another address-book tool.
3
Decide how updates should happen
Choose between periodic refresh requests and a model where the address owner maintains the current information.
BUILT FOR PEOPLE + AI
Addresses should be live data, not a stale field in a contact card.
OnceAsk gives people one current address to maintain and gives compatible assistants a permissioned way to resolve or request the delivery information they need.
Yes. Postable describes its online address book as free to use without requiring a card purchase.
What is the main difference between Postable and OnceAsk?
