Custom contact attributes let you store additional information about contacts beyond your standard contact attributes. For example, you can create custom attributes for membership status, customer type, or renewal links. Use them to segment audiences, personalize emails, and collect data via signup forms.
Create a custom contact attribute
Click Create attribute
Fill in the fields below
Name
Choose a short, clear name that describes what the attribute stores.
Description (optional)
Add a description so your team knows when and how to use this attribute.
Data type
Choose the data type based on how you plan to work with the attribute in MarketHype.
Data type | How it works | Example |
Single choice | Each contact can have one value for this attribute. Importing a new value will replace the previous value. | Attribute: “Customer type”
|
Multiple choice | Each contact can have multiple values for this attribute. | Attribute: “Customer type” |
True/False | A yes/no (boolean) attribute. | Attribute: “Member” |
Date | A date value in YYYY-MM-DD format. | Attribute: “Date of arrangement” |
Number | A numeric value. | Attribute: “Year of arrangement” |
⚠️ The data type cannot be changed later.
