Configure settings #
Extension settings #
Once you activate the extension, you will see the MailChimp tab on the page wp-admin > Ultimate Member > Settings > Extensions. On this tab, you can find these settings:
| Setting | Description |
|---|---|
| MailChimp API Key | This field requires you to input the API Key copied from your MailChimp account. The MailChimp API key allows Ultimate Member to integrate seamlessly with WordPress, syncing your user data with your MailChimp audiences. This integration helps automate email marketing and user management directly within your WordPress site. |
| Account delete action | Specifies what action to take when a user account is deleted. Choose from the following options:
Warning: The "Permanently delete" action removes a contact from the audience forever. Permanently deleted users cannot be resubscribed. Don't use this if you're not sure. |
| Account unapprove action | (Optional) See details here. Specifies what action to take when an account's status is unapproved or deactivated. |
| Groups and Tags view | Defines how to display Groups and Tags in the user profile field. You can choose from the following display options:
|
| Enable language field | Allows members to select their preferred language for receiving newsletters. When enabled, an additional option Default language will appear. |
| Default language | You can select the default language from the dropdown list, with English as the default option. This ensures members receive newsletters in their preferred language. |
| Enable requests cache | Improves performance by caching MailChimp API requests, reducing the need for repeated calls to the API. This setting must be enabled to access the Cache timeout option. |
| Cache timeout, s | (Optional) Specifies how long cached API requests should be stored, in seconds. The default value is 600 seconds (10 minutes). A longer timeout reduces API calls but may delay updates to MailChimp data. |
| Enable requests log | Saves detailed information about all requests and responses sent to the MailChimp API. This feature is useful for configuring and debugging the extension. Enabling this option reveals additional settings: Log all responses and Requests log. |
| Log all responses | (Optional) Logs responses for all API requests, including successful ones. Note that responses for failed requests are always logged by default. |
| Requests log | (Optional) Displays the saved log of API requests and responses. The log includes filtering and search functionality to find specific entries. You can also clear or refresh the log as needed. |
| Blocked Email Addresses | Specify a list of email addresses and domains that you want to block from being added to the audience. Add each email or domain on a new line. Addresses listed here cannot be added to the audience, and existing contacts will be unsubscribed during the next update if automatic sync is enabled. To block an entire domain, use a wildcard format such as *@domain.com. |
Requests log #
The requests log appears if the Enable requests log setting is turned on. It displays the time, status, method, request path, arguments, and referrer for each request to the MailChimp API. The extension stores a response for failed requests by default. If the Log all responses setting is turned on, the extension stores a response for all requests.
You can find the error details in the RESPONSE data. This information helps to configure and debug the extension.
You can also filter and search the requests log using the following dropdown options:
- All requests: View all recorded requests.
- Only requests with error: View only the requests that encountered an error.
- Only requests to add or update: View requests related to adding or updating records.
Additionally, you can view important requests for a specific user by clicking View log in the MailChimp column under wp-admin > Users.
User Role settings #
The extension adds settings to manage what members can edit from their accounts. Go to wp-admin > Ultimate Member > User Roles and choose the user role to modify. You will see the "Edit Role" page. Scroll down to the "MailChimp" section:
- Can manage groups?
- Can manage tags?

Configure fields #
Once you set up the connection and updated the page the Merge User Meta section will appear. This widget syncs form fields with audience fields.
Audience fields #
The audience should be set up in a specific way to get user data from the site. You have to create audience fields first. Do the following:
- Go to audiences and select the desired audience.
- Go to Audience > Settings > Audience fields and *|MERGE|* tags.
- You will notice that the form includes Email Address, First Name and Last Name. You can use these fields.
- Click the Add A Field button to add more fields. Select a field type and configure field's settings.
- Save Changes.
Image - Audience fields and *|MERGE|* tags screen, the audience fields.
Merge User Meta widget #
Once you create the needed audience fields go back to the connection and refresh the page. You'll see the widget Merge User Meta, which syncs form fields with the audience fields. In this widget, audience fields are shown on the left and form fields are shown on the right. You should set relationships between audience fields and form fields created on your site. Click the Update button to save changes.
Pay attention to the required fields and choices for the "radio buttons" and "drop-down" field types. Synchronization would fail if one of the required fields is empty. Synchronization may fail if the values of the "radio buttons" or "drop-down" field type doesn't match.
The widget has tools that help you to configure field relationships and avoid mistakes:
- required fields marked by the icon (!)
- information about field type and choices may be seen under the icon (?)
- a warning appears under the field if the configuration is wrong

Field type restrictions #
The address field in MailChimp is a complex field that consists of several subfields. You have to fill all required subfields or disable address field. Rules for address subfields:
| Subfield | Required | Recommendation | Example |
| Street Address | Yes | Must be merged with the required text field in the registration form | 20 W 34th St |
| Address line 2 | No | Should be merged with the optional text field in the registration form | next floor |
| City | Yes | Must be merged with the required text field in the registration form | New York |
| State/Prov/Region | Depends on country | It is empty or text if there are no states in the country. It is a code of the state if the country has states. | NY |
| Postal/Zip | Yes | Must be merged with the required text field in the registration form | 10001 |
| Country | Yes | Must be merged with the required dropdown field that contains country codes | US |
MailChimp does not support multi-select field types. However, multi-select form fields can be synced with text fields, where selected options are combined into a single string, with each option separated by a comma. For example, a "Sports" field with multiple selections could be synced as "Football, Basketball, Tennis."
To target specific contacts for a mailing campaign, MailChimp uses the "Segment" feature. You can create a segment by filtering based on the values stored in the text field containing multiple options. Simply use the "contains" rule to match the desired values.
Image - The Segment builder with the contains rule.
The dropdown and radio button fields in MailChimp can be synced with corresponding UM form fields (Dropdown and Radio) if the form field choices match the options in the audience field. However, we do not recommend using these field types, as synchronization can break if an option is added or removed on one side but not the other. It’s better to sync Dropdown and Radio UM form fields with a text audience field.
To simplify role syncing, we've added two virtual role fields that can be synced with a text field in the audience:
- Role slug: Returns the role ID (e.g., "super_editor").
- Role title: Returns the role title (e.g., "Super Editor").
Configure behavior on registration #
There are two ways to handle members on registration:
- Auto - Members are added to the audience after registration and approval if the Automatically sync contacts setting is enabled and their user role is selected in the Who can subscribe to this audience setting. A field in the registration form is non needed to use Auto mode.
- Manual - Add the MailChimp field to the registration form to allow members to sign up for newsletters manually. This field is visible in the registration form if the user role assigned on registration is selected in the Who can subscribe to this audience setting.
Follow these steps to add a field to the registration form:
- Go to wp-admin > Ultimate Member > Forms > Edit Form (Register).
- Click the "+" icon to add the new field.
- Select the MailChimp field.
- Set the title and label, then select the connection from the dropdown.
- Enable additional options if you need them:
- Checked by default - The checkbox appears checked.
- Manage groups - Additional field to select groups appears below the checkbox. Default groups are used if disabled.
- Manage tags: An additional field to select tags appears below the checkbox. Default tags are used if disabled.
- Manage language: If enabled, this option allows users to select and manage their preferred language from their account form.
- Checkbox label: This setting allows you to customize the label text for the MailChimp checkbox field. You can modify the default label to better suit your form's needs or provide more specific instructions for users.
- Click the Update button to save changes. The field should appear in the form.
