Need a different mix of mailboxes and domains than you currently have — for example fixing a plan you booked by mistake, or requesting a custom SMTP + domains setup? Here's how to make the change. For the billing mechanics behind removing or adding domains on your subscription, see How can I manage domains and billing when modifying my subscription?
Google Workspace: new allotment isn't currently available to purchase — current status: Google Workspace mailboxes.
Minimum purchase: new mailboxes are purchased in quantities of at least 10 at a time — this applies to both SMTP and Google Workspace mailboxes.
Changes you can make yourself
To add more mailboxes, go to Accounts → Add more email accounts in your dashboard.
When adding mailboxes, you can choose SMTP, or Google Workspace if you already have unused Google Workspace slots on your plan, and select the domain for each.
Custom plans we set up for you
Some SMTP + domain setups can't always be purchased as an exact split directly in the dashboard — for example "6 domains, no Google Workspace." For these, we'll adjust your plan for you. Just contact us with:
Your account email.
The number of SMTP mailboxes you want (if any — the minimum mailbox purchase is 10).
The number of domains you need.
Once your plan allowance is updated, you can create the new mailboxes under Accounts → Add more email accounts.
Only unused Google Workspace slots already on your account can be assigned to a domain; if you need more Google Workspace mailboxes than your plan includes, tell us the number (minimum 10) and we'll confirm the options.
Good to know
Each domain can be used for either Google Workspace or SMTP — not both at the same time. If you need to move an existing domain between the two, see Can I switch a mailbox/domain between Google Workspace and SMTP?
Buying a bigger plan or an add-on creates a separate subscription — it doesn't replace or reprice the one you already have. If you want your existing subscriptions folded into a single plan (with credit for the unused time), or you have two Maildoso accounts and want everything under one login, see Merging two Maildoso accounts, or combining several subscriptions into one plan.
If you booked the wrong plan, contact us and we'll help you switch to the right one.
Refunds follow our 30-day new-user guarantee. Domain registration costs are non-refundable. See Refunds and cancellations for the full policy.
Subscriptions cannot be purchased or increased via the API; you must use the dashboard to add new mailboxes. However, the API can be used to create mailboxes within already-purchased slots.
If you're not sure which setup is right for you, contact us with what you're trying to achieve and we'll recommend the best plan for your needs.
