What a year of email actually costs
Everyone below charges a monthly fee for the contacts you store. Inbox Penny charges $0.0010 for each email you send, and nothing in the months you send nothing.

At $0.0010 an email this row would be $6.00, but campaigns have a $1.00 minimum, so twelve small sends cost $12.00. The minimum stops applying above 1,000 contacts.
