All payments can be made by credit card or Paypal. Customers in Europe may also pay by direct debit. Payments by credit card (or by direct debit, in Europe only) are made via the international Payment Service Provider Adyen. Your banking information won't be saved by SendinBlue. After your first payment, Adyen will save your banking information in a fully encrypted and secure format, allowing you to make your future payments quickly and easily. When you pay with Paypal, you only have to provide the email address associated with your Paypal account. When you use this method, you activate the 1-click payment method. You can then cancel or modify your plan without entering your Paypal information again.
