Credits are units of payment used to send messages when you are on an Inkpact subscription or contract.
Each stationery size is associated with the following credit values:
1 x A6 handwritten, signed, sealed & delivered = 5 credits
1 x A5 handwritten, signed, sealed & delivered = 6 credits
1 x A4 handwritten, signed, sealed & delivered = 8 credits
Should you need more credits than your monthly bundle provides you can top up as and when you need. By paying in credits, you can run a variety of campaigns that might use different stationery sizes, and any excess credits will roll over to the next month (handy).
