Mailing 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 mailing address finder matches address locations from our network of over 200 million to your contact list, so you can talk to them from inbox to mailbox.

Address finder helps you create integrated campaigns, so you can make all your marketing channels work harder.


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 to many addresses or want to keep it small, you can tweak your budget to reach the audience size you want.

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 found in Mailchimp's address finder.

Mail postcards to your contacts, with or without addresses

When you set up a postcard to send to people on your list, the mailing address lookup tool will 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.


  • Postcards are a great way to reach and build a relationship with your target audience. Fortunately, there are several ways you can create a mailing list to send marketing postcards.

    The simplest way to get a mailing list is to use an address finder app, which is a tool specifically designed to find postal addresses for your business needs. You can use our mailing address finder for this purpose as well. With Mailchimp, we’ll automatically inform you how many addresses we’ve found with our postal address lookup before your card is sent. This way, you can ensure your postcard reaches the most people possible.

    To use our mailing address finder, you’ll need to have a Standard plan or higher. Our pricing plans are affordable, so you can grow your brand without spending all your profits. You can also try this tool on a one-time send postcard before commiting to a plan.

  • Mailchimp’s mailing address finder allows you to send printed postcards to your existing contacts, even if you don’t have an address on file. Our postal address lookup tool works by scanning our network of contacts—which has over 200 million people.

    Keep in mind that the addresses or contacts found won’t be added to your list, as data privacy is a priority for us.

    While sending physical mail may seem like a thing of the past, postcards can help your brand stand out and create a unique experience for existing contacts. For example, you can send a customer a birthday postcard with a promo code. Not only does this show you care about building the relationship between you and them, but it can give them a nudge in the right direction.

    In addition to helping you send marketing postcards to your contact list, you can also reach new contacts with our lookalike audience finder tools. This way, you can grow your audience, generate more leads, and boost sales.

  • While finding a mailing address with only an email may seem impossible, you can complete this task with Mailchimp. Our mailing address lookup will scan our extensive network to help you deliver postcards to individuals in your contacts.

    However, we may not be able to provide a postal address for every contact due to limitations in certain countries or states. For example, we currently cannot send postcards to California as a result of restrictions. We also won’t add any new contacts or missing addresses to your audience in order to respect the recipient's privacy.

    A mailing address finder can be a valuable tool when used correctly. To ensure you can stay in touch with future contacts, we recommend using a signup form to collect postal addresses. If you conduct business in the European Union, you must make sure these forms are GDPR compliant. Mailchimp signup forms are GDPR-friendly, allowing you to adhere to this law.
