When importing new lists for your contacts, you can optimize your data for those contacts by adding custom fields which you can use in your campaigns to tailor your content to those contacts.

Hey {first_name}, enjoy 25% off any purchase made this weekend at {closest_store_location}! 

This would be utilizing the first name data for that contact and a new custom field created called Closest Store Location.

Where are Custom Fields used in Mobiniti?

You can add unique custom fields to your contact settings so when you import those contacts, you can use things such a zip codes, ID numbers, or anything else specific to your use case.

When formatting your contact list, the new fields are the additional columns after the Mobiniti categories. This is the order in which columns for your data must be organized: Phone number, email, first name, last name, gender, birthday, custom field 1, custom field 2, etc...  Click here for the guide on how to format a contact list for importing.

These custom fields will also come in handy when creating a web opt-in page! You can ask for those specific fields on your web form. Click here for the guide to making a web opt-in page.
