Pay-as-you-go pricing is perfect for users who only plan to send campaigns once per month or less, (i.e. a quarterly newsletter).  Or for the new eMarketer who's starting to use email marketing periodically. 

With monthly pricing you can send unlimited campaigns to the following list sizes for one low monthly price!  This is great for marketers with more frequent mail outs and those who wish to leverage the power of Autoresponders.

The monthly amount is based on the number of active subscribers on all your lists at the time payment is due.  For example:  If you have 2 lists with 1000 active subscribers each, that's 2000 in total at the time of payment.

Subscribers who are on the unsubscribed, bounced, suppressed, unconfirmed or deleted lists will not be included in your active subscriber count.
