Nettica

Nettica has offered email services since 2005, and before that, actually sold an email server product. We decided to repackage it into "Software as a Service" long before the cool buzzword existed. Our service is a credit-based system, allowing you to add, change, or enhance the email services you have using those credits. Whether you have a single domain or twenty, you only have a single renewal date for all email services. If you add service throughout the year, those purchases are pro-rated to the current expiration date (similar to our Bulk DNS Service). If you run a small business and have to replace an employee, you do not have to make a purchase to do so. You delete the old email address and add the new one. That's credits at work. Credits can also be used to increase the size of a mailbox, or increase the size of your queue (for front-end and backup services).
