Frequently Asked Questions

? Is emailwiz hard to install?

No—emailwiz uses guided command-line prompts to handle most setup steps. You need a VPS with root access and a domain name, but the script automates component installation. The main manual task is configuring DNS records (MX, SPF, DKIM) after setup.

? Is it a good alternative to Google Workspace?

Yes for users prioritizing data privacy and control. Unlike Google Workspace, emailwiz lets you self-host your server, avoiding third-party data collection. However, it lacks Google’s collaborative tools (docs, calendars) and requires ongoing server maintenance.

? Is emailwiz completely free?

Yes—emailwiz is open-source (MIT License) and free to use. You only incur costs for your server hosting and domain name; there are no subscription fees or hidden charges.
