Yes, you can upload and map contact fields like first name, last name, and city using default fields.
If additional fields are needed, you can create custom fields while mapping columns during import.
These fields can be used in campaigns to personalize messages and improve customer engagement.
For example:
Hi $firstname, this is to remind you that car for your $car_model is due on $date.
The merge fields $first name, $car_model, and $date will be replaced with respective values for contacts while sending the campaign.
