Compare outcomes, not categories
A forwarding service and a productivity suite solve different jobs. Start with whether users need a new mailbox.
Email routing is not the same as a productivity suite.
Use MailerZ to preserve existing inboxes with custom-domain aliases; use Google Workspace when you need hosted organizational mailboxes and collaboration tools.
Plain-English verdict
Choose MailerZ for lightweight forwarding into inboxes you already own. Choose Google Workspace when each user needs a managed mailbox, calendar, drive and admin suite.

Tradeoffs to understand
No platform is the right fit for everyone.
MailerZ is not a replacement for Gmail mailbox storage, shared drives, calendar or enterprise identity administration.
Google Workspace’s per-user suite can be a better value when collaboration tools are required.
Forwarding into consumer inboxes can create deliverability edge cases outside MailerZ’s control.
Consider administration
Workspace centralizes users and data. MailerZ keeps the destination inbox provider unchanged.
