Currently, when I'm paying to send a campaign - or do a test - myself, I'm billed in US$. When my clients have access to their accounts, I can change their billing currency to GBP. Is it possible for me to pay in GBP, not just my clients?
At this time the admin accounts can only pay in USD. The best you could to for your own campaigns is to set yourself up as a client and use that account for your sends.
Ok, thanks Davida. I'll consider doing that.
