Dimensions summary
You pay by the hour for the software running on a Windows Server 2022 instance. Pricing scales with the EC2 instance type you choose. Each dimension maps to a specific instance size and family, from small general-purpose types up to large memory, compute, storage, and GPU-based machines. Smaller instances carry lower hourly rates; larger instances with more CPU, memory, or specialized hardware cost more per hour. You select the instance that fits your email server workload. The email software itself is the same across all instance types; only the underlying compute capacity and hourly rate differ.
Top-of-mind questions for buyers
Each hourly unit covers one running EC2 instance of the type you select. The instance runs Windows Server 2022 with hMailServer preinstalled and configured on a SQL backend. It supports IMAP, SMTP, and POP3 protocols, plus features like anti-spam, SSL encryption, and domain management.
The hourly software rate meters running time only. A fully stopped instance does not accrue software charges. Underlying AWS storage fees may still apply while the instance is stopped, but the software licence bills per running hour of the instance you selected.
No. The hMailServer software is identical across every instance type. Only the underlying compute capacity and the hourly rate change. A larger instance gives more CPU, memory, or specialized hardware for heavier email workloads, but the features and protocols stay the same.
