This is the single reference for how Google Workspace mailboxes behave in Maildoso. Google Workspace mailboxes are provisioned through a third-party Google Workspace provider, so several things — deleting, recreating, renaming — work differently from standard SMTP mailboxes. Read this before you delete or change a Google Workspace mailbox.
Is Google Workspace still available?
Google Workspace mailboxes are still supported on plans that already include Google Workspace allotment — you can keep creating, using and recreating mailboxes within that allotment. New or additional Google Workspace allotment is not currently available to purchase, so all new mailbox purchases are SMTP mailboxes. The minimum purchase is 10 mailboxes at a time, as for SMTP.
Need more capacity now? Add SMTP mailboxes — see Adding more mailboxes to your plan and current Pricing (the Packages & Add-ons page in your dashboard always shows the current price). For a different mix of mailboxes and domains, see Changing or switching your plan. This article is the current status for Google Workspace availability — if you read something different elsewhere in the Help Center, this article wins.
Why the Google option might show 0 available or greyed out
If Google shows greyed out or 0 available in the provider choice when you create mailboxes, it's usually one of these — not a bug:
Your plan has no unused Google Workspace slots, and new allotment isn't currently purchasable.
Your current plan is SMTP-only and never included Google Workspace quota.
Your slots are still taken by mailboxes you deleted that are waiting for their removal date — see Deleting a Google Workspace mailbox below.
You just checked out and the quota hasn't applied yet — wait a few minutes and refresh.
The specific domain isn't Google-eligible — see Why are some of my domains not eligible for Google Workspace?
The domain already has the maximum of 5 Google Workspace mailboxes, isn't fully Active yet, or is already linked to Maildoso SMTP — see Setting up domains and mailboxes.
If you signed up or added an add-on expecting Google Workspace mailboxes and that allotment isn't purchasable, contact support — we'll confirm what your plan includes and sort out billing if you were charged for something you can't use.
Setup awaiting and Failed on a Google Workspace mailbox
Google Workspace mailboxes usually take a few hours to provision; until then they show Setup awaiting / Setup processing (called "Pending" in older guides). If a mailbox stays in setup for more than 24–48 hours, or shows Failed, don't delete and recreate it — contact us with the mailbox address. Common causes:
a missing first or last name (Google requires both);
the same address was deleted and is still waiting for its removal date (see below);
the domain's Admin mailbox was deleted or cancelled — then every new Google Workspace mailbox on that domain fails (see The "Admin" mailbox).
Forwarding on Google Workspace mailboxes
Google Workspace mailboxes don't use the Maildoso Master Inbox. A forwarding address is optional; to set or change one, select the mailboxes on the Email accounts page and use Bulk actions → Change forwarding for Google with an external (non-Maildoso, non-Google) address. To stop forwarding, remove the address there and save — the Forwarding Address column then shows Not set, which is the expected state, not a warning. If the change doesn't take effect, contact us. More: Forwarding addresses and the Master Inbox.
Deleting a Google Workspace mailbox — how it really works
A Google Workspace mailbox can't be deleted instantly. Whether you delete or cancel it, the mailbox is scheduled for cancellation, not removed:
Its status changes to Deletion scheduled · <date>. The date is the end of the current billing period of your Google Workspace line.
Until that date the mailbox is still active — it sends, receives, warms up and stays connected to your sequencer, and it still takes up its slot.
On that date it is removed for good. Neither you nor our support team can remove it earlier.
Until the removal date, the same address can't be created again. If you try, the new mailbox shows Failed — that's expected, not an error to retry. Wait for the date, or use a different address.
Once removed, the slot returns to your Google Workspace allotment and you can create a new mailbox in it on any Google-eligible domain. The new mailbox is brand new: warmup and reputation start from zero — plan on 10–14 days of warmup.
Once removed, a mailbox can't be restored with its data. If you change your mind before the date, contact us and we'll check whether the cancellation can be stopped.
This applies to regular mailboxes only — deleting or cancelling the domain's Admin mailbox cancels the whole Workspace of the domain (see below). Deleting a Google Workspace mailbox doesn't free a slot right away, so it isn't a quick way to make room for new mailboxes — plan replacements ahead of your Google billing date.
Billing dates. Google Workspace mailboxes run on their own billing line, which can have a different cycle date from your main plan. The Google line is charged at the start of its cycle and scheduled mailboxes are removed at the end of it — e.g. a line that runs from the 20th to the 20th is invoiced on the 20th, and mailboxes deleted during that cycle show "Deletion scheduled" for the following 20th. Scheduling a deletion doesn't lower the number of Google Workspace slots on your next invoice by itself: contact us before the renewal date with the number of Google Workspace mailboxes you're keeping and we'll reduce the Google line.

Can I change (rename) a Google Workspace mailbox address?
No. The address of a Google Workspace mailbox (the part before the @) can't be changed — not in the dashboard and not by our support team. The only way to get a different address is:
Delete the mailbox you no longer want — it stays active until its removal date. Never use the Admin mailbox for this.
After the removal date, create the new address in the freed slot — or right away, if you already have an unused Google Workspace slot.
Warm the new mailbox up for 10–14 days before real outreach.
The display name (first/last name) is different — see Change names of mailboxes. Moving mailboxes to a different domain works the same way (new mailboxes, fresh warmup) — see Can I move my mailboxes to another domain?
The "Admin" mailbox — don't delete or cancel it
On the Email accounts page, one Google Workspace mailbox per domain carries a small Admin badge (and you can filter by Admin account). It's the administrator (primary) user of that domain's Google Workspace. It sends, warms up and is billed like any other mailbox.
Deleting or cancelling the Admin mailbox deletes the domain's entire Google Workspace, and the domain can't be used for Google Workspace again for about 11 months. That means:
Every other Google Workspace mailbox on that domain is cancelled with it — even if some still look Active for a while.
You can't create new Google Workspace mailboxes on that domain any more — every attempt ends in Failed, and recreating them won't help. Deleting the remaining mailboxes doesn't unlock the domain either.
Our Google Workspace provider requires a domain to stay unused in Google Workspace for about 11 months before it can be added again.
Can it be undone? It depends on how far the cancellation has gone:
Admin mailbox still shows "Deletion scheduled" — the cancellation can usually be stopped, and the domain's Workspace is kept with all its mailboxes. Contact support right away: this is only possible before the removal date.
Admin mailbox already removed — the Workspace and its mailboxes can't be recovered. Use your free Google Workspace slots on other domains. In rare cases the domain can be released earlier, but only through a manual process with the provider that isn't guaranteed and has no fixed timeline — and everything on the domain is rebuilt from scratch, with no data and fresh warmup.
So: delete the Admin mailbox only if you're giving up Google Workspace on that domain entirely, and never use it to free a slot or "swap" it for a new address. If it has already happened, contact support right away — don't recreate anything.
Can Google Workspace mailboxes be transferred to or from Maildoso?
Out of Maildoso: no. Google Workspace mailboxes provisioned through Maildoso can't be transferred to another reseller, provider or your own Google Workspace account. The Workspace for each domain is held under our provider's reseller account — not under Maildoso's own account and not under yours — so there is no transfer token or admin access we can hand over. This is a limitation of how the mailboxes are provisioned, and support can't make an exception. What can move:
Domains registered through Maildoso can be transferred to your own registrar — see Transferring your domains out of Maildoso. Once a domain's nameservers leave Maildoso, the Google Workspace mailboxes on it stop working.
Mailbox contents — before the mailboxes are removed, you can export mail from each mailbox yourself with standard Google tools (such as Google Takeout) or an IMAP client, using its sign-in details — see Logging in to your Google Workspace mailboxes. We don't migrate contents to another provider for you.
If you're moving to your own Google Workspace, the domain must first be free of our provider's Workspace: cancel the domain's Google Workspace mailboxes here (including the Admin mailbox), wait for the removal date, then transfer the domain out and set it up fresh. Nothing carries over.
Into Maildoso: existing Google Workspace tenants and mailboxes can't be transferred to Maildoso (reseller transfer authorization isn't supported). Domains themselves can be moved through a registrar such as Dynadot and connected here, but their existing mailboxes stay with your current Google Workspace.
Switching between Google Workspace and SMTP
A domain serves either Google Workspace or SMTP, not both. Switching to Google Workspace requires unused Google Workspace allotment on your plan — see Can I switch a mailbox/domain between Google Workspace and SMTP?
Cancellation, sequencers and warmup
If you cancel a subscription that includes Google Workspace mailboxes, those mailboxes are deleted at the end of the billing period, and after the renewal date they can't be restored on Google's side — export anything you need first.
Google Workspace mailboxes connect to sequencers through Settings → Sequencers for GW and Export accounts → Add … Google accounts to Sequencer (OAuth), not from the CSV — that's why the CSV shows no IMAP port for them. See Connecting Google Workspace mailboxes to sequencers.
Google Workspace warmup settings differ from SMTP: 25 warmup emails/day, 30% reply rate, increase by 2–3 a day, and at most 10 campaign emails/day after warmup. Warmup filters don't hide warmup mail on Google Workspace — see Managing warmup emails on Google Workspace mailboxes.

Still stuck?
Contact support with the mailbox address, the domain, and roughly when you created or deleted it. Please don't delete, recreate or rename Google Workspace mailboxes to work around a problem — tell us first, so nothing ends up in a state that's hard to recover.
