Create additional subscriber fields
While your subscribers' profiles provide only first name and email address fields by default, you can create additional fields for storing other information like your subscribers':
Last name
Phone number
Favorite color
You can view your subscribers' custom fields from their respective subscriber profile. Click the dropdown icon next to the Custom Fields section in the left sidebar to expand the list of custom fields.
Custom fields that don't have a value will be hidden behind a Show # empty fields button. Click the button to reveal them.
Here's how to add and manage custom fields.
Adding new custom fields
There are a few ways of adding new custom fields, with the main way being from a subscriber profile.
When you add new custom fields, they'll appear for every subscriber in your account. If you need to, you can delete custom fields from individual subscribers afterward.
From a subscriber profile
Go to the Subscribers page in the navigation and click any subscriber on the page to access their subscriber profile.
NOTE: If you don't have any subscribers yet, add your email address as a new subscriber to your account so you can follow these steps. You can always delete your email address from your account later if you want.
Click the three vertical dots (⋮) next to Custom Fields in the left sidebar. Then, click Add new to add a new custom field.
Enter your desired custom field name (e.g., "Favorite color") into the Field name field. You can optionally also enter a custom field value (e.g., "Blue") for this specific subscriber.
Click Add field to save your custom field.
The custom field will be added to every subscriber in your account. This is even though you added the custom field to one specific subscriber's profile.
Other ways of adding custom fields
If you are setting up your Form or Landing Page to display custom fields, you can directly create new custom fields from the Form or Landing Page builder's Custom field setting.
Alternatively, you can also create new custom fields when adding custom field-related steps to a Visual Automation (e.g., the Set custom field action).
Renaming your custom fields
Renaming a custom field means changing the name associated with it (e.g., "Last name"), but not the text it stores (e.g., "Jughead"). Custom field name changes will be reflected across all subscribers in your account.
To rename a custom field, open any subscriber profile and click the three vertical dots (⋮) next to Custom Fields in the left sidebar > Edit.
Click the name of the custom field you want to rename. Change your custom field's name, and then click the checkmark icon to save your changes.
Updating custom field values
Updating a custom field's value means changing the text the custom field stores (e.g., "Jughead"), but not the name associated with the custom field (e.g., "Last name"). Custom field text changes will be reflected only in the subscriber profile whose custom field you've updated.
To update custom field text manually, open the subscriber profile whose custom field text you want to change.
Click the three vertical dots (⋮) next to Custom Fields in the left sidebar > Edit.
Enter or edit the text of the relevant custom field. Then, click the checkmark icon to save your changes.
Deleting custom fields
Deleting a custom field means removing the custom field—both its name and its stored text—entirely. If you want to delete a custom field's stored text while still keeping the custom field, follow our instructions for updating custom field text instead.
When deleting custom fields, you can delete a custom field for only a single subscriber or for all subscribers.
For a single subscriber
To delete a custom field for a single subscriber, open that subscriber's subscriber profile.
Click the three vertical dots (⋮) next to Custom Fields in the left sidebar > Edit. Then, hover your cursor over the custom field's name.
Click the trash can icon that appears, followed by Remove from this subscriber.
Click Yes, remove in the pop-up window to confirm the deletion.
For all subscribers
To delete a custom field for all subscribers, open any subscriber profile.
Click the three vertical dots (⋮) next to Custom Fields in the left sidebar > Edit. Then, hover your cursor over the custom field's name.
Click the trash can icon that appears, followed by Delete for all subscribers.
In the pop-up window, type "DELETE", and then click Yes, delete to confirm the deletion.
Considerations for custom fields
Here are considerations to keep in mind when setting up custom fields:
Custom fields aren't made for paragraph text
As a result, our Forms and Landing Pages aren't intended to be used as contact forms. If you need a contact form, try searching our Kit App Store for a suitable third-party form app.
All custom field data is stored as plain text
For example, while you can store dates in custom fields, these dates will be stored as plain text. Kit won't detect those values as dates or be able to perform date-based logic on their values.
Working with date data
Dates in custom fields need to be saved in one of these formats:
yyyy-mm-dd
yyyy-mm-dd HH:MM
Otherwise, date and time Liquid filters you apply to these custom fields won't work.
Each Kit account is limited to 140 custom fields
If you try to create more than 140 fields, you'll see a response of "400."
