How to bulk assign a group of customers to specific VIP tiers
⚠️ Important: Your VIP program must be enabled before importing a bulk VIP list. If the VIP program is not active, the import will not correctly assign customers to VIP tiers.
First, prepare a CSV file with customers' VIP tier status' ready to import. To ensure that your customer list is successfully imported into Marsello, it is important to update your CSV file format following the below steps:
1. Open your CSV as a spreadsheet of your customers
2. Delete all columns except the following:
-
First Name (values are required)
-
Last Name (optional)
-
Email Address (values are required)
-
Mobile (optional)
-
VIP Tier Name
⚠️ Important: The customer's first name and email address are required. If these values are missing, the CSV file cannot be imported into Marsello.
3. Update your column heading text to be the following:
-
First Name Column → Firstname
-
Last Name Column → Lastname
-
Email Address Column → Email
-
Mobile Number Column → Mobile
-
VIP status → Tiername
4. Review customers' tiers. Ensure that your spreadsheet 'Tiername' column follows the following guidelines:
-
Customer's 'tiername' value must match the tier name within your VIP Program.
If the VIP Program's tier name is "Gold Tier" it must match this exactly. e.g. If the tier name in the spreadsheet is "Goldtier" or "Gold-tier" it will not assign the customer to that tier on import. -
Customer's 'tiername' value is empty or null the importer will automatically check if they are in a VIP tier already, if not they will be assigned to the base tier of your VIP Program.
-
Customer's 'tiername' is 'basetier' they will be assigned to the bottom tier of your VIP Program.
5. Save your spreadsheet as a .CSV file
💡Quick Tip: To save a file as a .CSV, in the spreadsheet tool, this can often be found under Export to or Download as in the settings menu.
