Start in the email tab

You may need to purchase additional e-mail credits if your account does not have any included e-mails.

Press the Purchase Credits button from the Orange menu

In the new browser window that opens, enter the amount of additional credits you'd like to purchase. You'll need to enter an amount at least to cover the amount of e-mails you wish to send for your current campaign. If you have a voucher code, please see this guide.

Confirm the amount and enter your payment method, then press the green Pay Now button.
