You have several options for the payment of your Mailytics account. The amount you pay is based on the subscription you choose. To see what subscription options are available, please look at our pricing page at 

During the registration process you will first be prompted to select your subscription and then you must choose between a monthly or yearly payment plan. All subscriptions are billed on a recurring basis, either monthly or yearly, depending on the payment plan you choose.

You will not need to input your card details or any billing info during the registration process. However, after your free 14-day trial you will need to provide your billing details or else your account will be deactivated once the trial ends. Once you enter your card details and the free trial ends, you will be billed according to the subscription option and payment plan you chose during registration.
