Before you start, make sure you have the Promotion published to the Live environment and that the vouchers have been created (see the instructions for doing this here) - download the vouchers from the Promotion so you have the codes handy.
- Create a csv file using this template - choose whether you wish to override existing vouchers on any of the accounts or not. False will mean it skips past that customer as they already have a voucher, True means it will overwrite the voucher that's on that customers account
- In Telesales, go to 'Tasks' and 'Redeem Promo Codes'
- Click 'Choose File' on the detail page and select your csv. then click 'execute task'
- Click the 'Jobs' tab and it will show at the top. If it says 'UNKNOWN' under the 'Exit code' column it means it is still processing.
- Once completed, click 'details' and 'get report'
- This will download a spreadsheet with a list of the customers and a result of the load.
