Use this page to manage credits bought to send SMS campaign.
When you buy credits from MailUp, they are all attributed to your MailUp account (whose number is highlighted in bold). From this page, you can split credits between you and your customers.
Remember to assign all credits before clicking "Save", otherwise you won't be able to save the credits' assignation (the Unassigned Credits counter must hit 0)
Trial accounts
Credits cannot be attributed to trial accounts. Only regular paid accounts can receive credits.
