How To Import Email Addresses with CSV Upload for Product Purchase Restrictions

Bulk Import Authorized Customer Emails in Seconds

Managing large lists of authorized customer email addresses just got a whole lot easier. Our WooCommerce plugin Advanced Product Purchase Restrictions now includes a powerful CSV import feature that lets you upload hundreds of email addresses at once.

Why CSV Import?

If you have a large customer base or need to manage extensive email lists for product restrictions, manually typing or pasting email addresses becomes impractical. CSV import solves this problem by allowing you to:

• Import hundreds of emails in a single upload
• Use existing customer lists from Excel, Google Sheets, or CRM systems
• Save hours of manual work with automated processing
• Ensure data accuracy with built-in validation

How CSV Import Works

The process is incredibly simple:

1. Prepare your CSV file with email addresses
2. Upload the file using the import interface
3. Automatic processing validates and imports emails
4. Instant results with success/error feedback

Supported CSV Formats

Our Advanced Product Purchase Restrictions plugin handles multiple CSV formats automatically:

Single Column (One email per line):

customer1@example.com
customer2@example.com
customer3@example.com

Multi-Column (Comma-separated):

customer1@example.com,customer2@example.com,customer3@example.com

Mixed Formats: The plugin intelligently parses any combination
