Email rates are $.0675 per email which is $.675 cents per 1000 emails billed in addition to the monthly rate. These are billed per email and not at a monthly rate like other services which is a great savings. SMS message fees depend on the carrier and range from $.02 to $.05 per message. You are required to keep a card on file to pay these fees and will be billed $10 initially and in $10 increments when your balance is low.
