We encourage you to not believe anything that we say about our products! And that’s why, from our inception, we’ve always made a full-featured, non-expiry 4-user version of PostMaster Express and PostMaster Enterprise available for your evaluation.
That’s right, a full-feature AND non-expiry version, so if your requirement is for 3-users, then you could use this in perpetuity. (One ID is locked for administrator, and this cannot be changed). You can choose between the light-weight, yet feature-loaded PostMaster Express and the full-loaded and customizable PostMaster Enterprise
