When you set up Google Workspace mailboxes, you may see a message that "some domains are not eligible for Google Workspace." This is a normal eligibility check performed by Google — it is not a bug or a problem with your domain, and it is common for freshly registered domains.
Eligibility is decided by Google, not by Maildoso, so we can't force a domain to become eligible.
Your options:
Register anyway — use the domain with our SMTP infrastructure instead of Google Workspace. If you later want to move that domain to Google Workspace once it's eligible, see Can I switch a mailbox/domain between Google Workspace and SMTP?
Choose different domains for the Google Workspace mailboxes.
"Google" shows 0 available / I can't select Google mailboxes
If the Google option on the mailbox-creation screen is greyed out or shows 0 available, it's usually one of these — not a network/VPN problem:
Your plan has no Google Workspace allotment. If you bought an SMTP-only plan, there's no Google quota to draw from, so the Google option stays at 0. New Google Workspace allotment isn't currently purchasable — contact support if you're not sure whether you already have unused Google Workspace slots on your account.
Brand-new purchase. Right after checkout the quota can take a few minutes to apply. Wait and refresh.
The domain isn't Google-eligible (see above) — pick an eligible domain or use it on SMTP.
If you're not sure which option fits your plan, contact support and we'll help you decide. For more on Pending status, provisioning times, and other Google Workspace availability questions, see Google Workspace mailboxes: availability, provisioning, and "0 available" errors.
