# Connect your form to Mailchimp
> Add new Mailchimp contacts and update existing ones from a Fillout form to grow your newsletter audience. Set audience fields and add tags to contacts based on conditions in your form.
## What is Mailchimp?
[Mailchimp](http://mailchimp.com/) is an all-in-one marketing platform that helps businesses and individuals design, create, and manage email campaigns, build landing pages, automate marketing processes, and analyze audience engagement to reach their marketing goals effectively.

## How it works
Click `Integrate` from the top menu followed by `Mailchimp`.
When creating your form, make sure to set the email, name, and other fields you would like to link to your Mailchimp mailing list to **required**.
Choose which **account** and **audience** you would like to create or update contacts in, then click `Continue`.
[Match the fields](https://www.fillout.com/help/additional-integration-mappings#how-to-map-fields-manually) in your Fillout form to the corresponding fields in your Mailchimp audience. For example, link the email address field by its respective question.
`Publish` your form once everything’s set.
That's it! Answers from new submissions will now appear in your Mailchimp audience list.
If a contact with the provided email address already exists, Fillout will automatically update the existing contact's information.
## Add tags
You can add Mailchimp tags to new contacts automatically to help segment your email audiences. `+ Add tag` and choose from the dropdown.
To add a tag to specific contacts, toggle the `Add conditionally?` switch. `Set conditional logic` and choose when to apply it. For example, tagging users with their "Occupation".
Remember to click `Publish` on the upper right corner after making any changes to the integration.
## Specify a condition
You can run your integration only when a specific condition is met. Check out this [guide](/conditional-integration).
