How does your pricing and billing work?
Elastic Email is like a pre-paid phone. Costs are deducted from credit that can purchased via Credit Card or PayPal. Each account gets 5000 free emails every day. If an account sends more than 5000 emails in a day then emails are charged at a rate of $0.09/1000. If an account enables "Advanced Marketing Tools" then there is a contact storage fee. This fee is based on the number of contacts in the account. For the first 100,000 contacts it is $0.29/1000 per month, the next 1,000,000 contacts cost $0.19/1000 per month, and any remaining contacts cost $0.19/1000 per month. All costs are broken down into a daily charge. Private IPs are $0.79/day. Attachments cost $1/GB.
