Lists are the preferred way of managing your contacts in Loops.

In addition to providing fine-grained control over your audience, using Lists will automatically generate a branded Preference Center for contacts in your audience, allowing them to easily manage their subscription preferences.

Lists can be public or private and contacts can belong to many, one, or no lists.

Lists are an optional feature. You can use Loops without lists but if you’d like finer-grained control over your contacts and the types of communication they receive, lists are available on any plan tier.

List visibility

Each list you create can be Public or Private.

By default lists are private, meaning they are only shown to their subscribed contacts (non-subscribers won’t be able to see or subscribe to private lists in the Preference Center).

If you want to allow general opt-in to a list, you can set the list visibility to Public. Public lists will be shown to all contacts in the Preference Center.

You can also sign up new subscribers to public lists with Forms.

Both private and public lists are visible within your Loops admin and can be used for filtering contacts when sending campaigns and loops.

Preference Center

The Preference Center allows your contacts to manage their own subscription preferences.

Preference Center

A link to the contact-specific Preference Center is automatically added to each marketing email sent from Loops. You can link to the Preference Center in MJML emails by using the {unsubscribe_link} dynamic tag.

You can upload a company icon to brand your Preference Center. This option is shown just below your mailing lists in the Lists settings page.

You can brand your unsubscribe page with a company icon even if you do not use the lists features.

Within the Preference Center, contacts will see:

  • your company icon (if uploaded)
  • the names and descriptions of all public lists
  • the names and descriptions of all private lists they are subscribed to
  • the option to unsubscribe from each list they are subscribed to

Utilizing lists

Here are a few ways you can use lists to send emails and organise contacts.

list

Send campaigns to a list

Instead of sending campaigns to your whole audience, you can send emails to a specific list.

1

Choose a campaign

Create a campaign or edit an existing one.

2

Select the list

On the Audience page, select the list you want to send to.

Select a mailing list

Users not subscribed to the selected list will not receive the campaign.

3

Apply additional filters

Optionally, you can apply additional filters or segments to further refine your audience.

Manually add contacts to lists

How to add existing contacts to your different mailing lists within Loops.

You cannot edit the list subscriptions of contacts who have been unsubscribed from your audience. Likewise, if a contact unsubscribes from a list via the Preference Center, they cannot be resubscribed by your team.

Individual contacts

1

Go to Contacts

Go to your Audience page.

2

Select a contact

Click on the contact you want to manage.
3

Manage subscriptions

In the contact details page, click on Subscribed to reveal the mailing list dropdown. Manage subscriptions Toggle each list on or off as needed. Click Save changes in the top right to apply the changes.

Bulk contacts

You can easily add any filtered group of contacts to a specific list on the Audience page.

1

Go to Audience

Go to your Audience page.

2

Filter your audience

Add filters to segment your audience into the group of contacts you’d like to add to a list.

3

Add contacts to a list

Click the ••• menu icon on the far right-hand side of the audience filters, select Add to mailing list and then select the list(s) you want to add the contacts to. Add to list

Upload a CSV to a list

If you want to import contacts to a list in bulk you can use our CSV importer.

In the final stage of the form you can select a list, which will add all contacts (new or existing) in the CSV file to that list.

Add contacts to lists with the API

Utilizing the Loops API you can programmatically add and remove contacts to and from Lists.

When creating a contact, updating a contact, or sending in an event with the API, you can include a mailingLists object in the payload.

This mailingLists object is a key-value pair of list IDs and a subscription status. The subscription status can be true or false.

{
  "email": "[email protected]",
  "mailingLists": {
    "list_123": true,
    "list_456": false
  }
}

In this example, the contact would be subscribed to list_123 and unsubscribed from list_456.

Mailing list IDs can be found in the app (click the ID to add it to your clipboard) or by using the API.

Visibility toggle

Add contacts to lists with forms

If you use a form on your website you can subscribe contacts to specific lists.

When exporting HTML from the Forms page in Loops, choose a list from the Settings tab.

Select a list from the form settings

Adding contacts to a list via a form only works with public lists. The option to select a list will only appear in the form settings if you have at least one public list.

If you already have a form in place or are using a custom form you can add a mailingLists parameter to the form body with the value a comma-separated list of mailing list IDs.

HTML example:

<form>
  <input type="email" name="email" required />
  <input type="hidden" name="mailingLists" value="list_123,list_456" />
</form>

JavaScript example:

fetch(formEndpointUrl, {
  method: "POST",
  body:
    "mailingLists=" +
    encodeURIComponent("list_123,list_456") +
    "&email=" +
    encodeURIComponent(emailInput.value),
  headers: {
    "Content-Type": "application/x-www-form-urlencoded",
  },
});
