Royalcraft review for Ultimate Postal Code Blocker

Jan. 23, 2026

Works perfectly, The CSV I uploaded initially contained too much information so a good tip is to only include the postal codes you need blocked and not adding the city name in a separate column as this caused the entire city to be blocked for myself. Contacted their help and received a phone call within 10 minutes as their emails weren't going through but I had managed to fix the issue myself as the app is that easy and intuitive to use
