Address Finder

Reach your contacts through the mail—no addresses needed

Send beautiful postcards to your audience, even if you only have their email addresses. Mailchimp’s address finder matches mailing addresses from our network of over 200 million to your list contacts, so you can talk to them from inbox to mailbox.

See how many more people you can reach with postcards

Mailchimp shows you how many addresses we've found for your audience before we send a postcard on your behalf. We take data privacy seriously, so we won't add any addresses or contacts to your list. Address finder is free to try out, and you can upgrade to a paid plan to mail your postcard to any addresses we find right from the campaign builder.

Mail postcards to your contacts, with or without addresses

When you set up a postcard to send to people on your list, we’ll look for contacts with missing mailing addresses and try to match them with one of the millions of postal addresses that power our audience data tools.

Re-engage your contacts based on how they like to hear from you

Postcards give you a way to keep your brand in front of contacts who don’t always read your emails (they can help re-engage these people, too!). Segment your list based on email marketing status, then create a postcard and target the addresses we find through the mail.

Works on any budget

Tell us how much you want to spend, and we’ll show you the total number of postcards you can send. Whether you’re planning a big mailing or want to keep it small, you can tweak your budget to reach the audience size you want.
