What are custom fields?
Custom fields are your own profile or product information that you add on top of the standard Reloadify fields. For profile information, think of a shoe size, your customer's car brand, a license plate, or the name of a pet. For product information, think of specific brand details or a custom attribute of an order.
You decide which data you add and what you call it.
Why do you use custom fields?
Custom fields take your emails to the next level. You could send accessories for your customer's car brand, or a birthday email for their dog.
You also use the data to filter and segment in the renewed rule system.
How do you create a custom field?
Go to Settings > Custom fields and choose New property.
Type. Choose what the data belongs to.
Data type. Choose which type of data you're adding:
String: a series of letters/numbers, such as text or a specific code.
Integer: a whole number without decimals, for example
1234.Date: a date (without a time). Keep this order, otherwise Reloadify won't recognize the date: year-month-day. For example:
2026-08-18.Datetime: a date with a time. Keep this order, otherwise Reloadify won't recognize the date and time: year-month-day hh:mm:ss +timezone, for example:
2026-08-18 11:30:00 +0200. For Amsterdam/Dutch time, use +0200.Boolean: a value that's true or false. The values for this are
TRUEorFALSE.
Name. Give your property a name, for example 'License plate'.
Description. Briefly describe what the data contains, for example 'License plate of the profile'.
Save your property. You'll find it in the overview of your custom properties, along with the reference you need to link data to it.
How do you upload custom data?
You upload your data in 3 ways:
CSV. Upload a CSV file with the reference of your property as the column title.
API. Send your data through an API endpoint.
Zapier. Link your data through Zapier. Once you've created custom fields, they're also available in Zapier. Read more
Uploading custom data via CSV
To link the data to your new property, you need the reference of the property. You'll find this in the overview of your custom properties.
Your CSV file will look like this:
Upload your CSV file (via Import > CSV file > New import) and select the desired language. Match the columns from the file to the correct fields in Reloadify.
Uploading custom data via API
Prefer not to upload your custom data manually? Send the data through the API. Read exactly how to do this in our API documentation.
Editing or deleting custom data in bulk via CSV
Want to edit existing data? Change the data in your CSV file and upload it again. Reloadify automatically overwrites the old data.
Want to delete custom data? Keep the column title (the reference of your property) in place, but clear the rest of the column. Upload the CSV file again.
Note: leaving a column empty deletes the data for all profiles in that file. Want to delete the data for just one profile? Do an import with only that one profile in your CSV file.
Where do you find your custom data?
You'll see your custom data in the overview of your profiles.
In the renewed audience filters, the filter based on your custom field automatically appears, based on the data type you chose.
