Yes. You can choose the billing style that suits you from the Packages & Add-ons page, which has two options: a flexible Custom plan, or ready-made Packages.
Custom plan (flexible, monthly)
A flexible monthly plan where you choose exactly how many Maildoso (SMTP) mailboxes and domains you want, using the sliders. (New Google Workspace allotment is not currently available to purchase — see the note below.)
Mailboxes are added in bundles (minimum 10 at a time), and the per-mailbox price depends on how many you have in total — larger volumes get a better per-mailbox rate. See How much do SMTP mailboxes cost? Volume pricing tiers for the exact rates. If you're expanding an existing plan rather than starting fresh, see Adding more mailboxes to your plan for the step-by-step add-on flow.
On the Custom plan, domains are purchased separately at $15 per domain, per year (a fixed price, with no volume discount). Best Practices for Domain Usage: When purchasing domains, consider using domains similar to your company name for cold outreach campaigns to maintain brand consistency. Additionally, keep your primary business email domain and main website domain separate from domains used for outreach to minimize risks and ensure the security of your primary domain.
Packages (fixed-size bundles)
Packages are ready-made bundles at a fixed mailbox count, rather than a slider you configure yourself — a good fit if you want a set size instead of building your own. There are two package types, shown as tabs on the Packages & Add-ons page:
Monthly packages
30 mailboxes — $2.50/mailbox, $75/mo total
300 mailboxes — $0.75/mailbox, $225/mo total
1,000 mailboxes — $0.50/mailbox, $499/mo total (the per-mailbox figure is rounded; $499 is the package price)
Monthly package rates follow the same volume pricing as the Custom plan — domains aren't included and are purchased separately, same as on the Custom plan.
Quarterly packages (legacy)
Quarterly packages are a legacy plan type — still available and fully supported, but no longer the default option. Unlike the Custom plan and Monthly packages, quarterly packages include a set number of domains at no extra cost:
32 mailboxes — $3.10/mailbox, $299/quarter (~$99/mo), 8 domains included free
68 mailboxes — $2.40/mailbox, $499/quarter (~$166/mo), 17 domains included free
400 mailboxes — $1.80/mailbox, $2,199/quarter (~$733/mo), 100 domains included free
Because quarterly packages bundle domains in, the per-mailbox rate is higher than the equivalent Monthly package or Custom plan tier — factor in the included domains when comparing total cost, not just the per-mailbox price.
Google Workspace availability (current status): Google Workspace mailboxes are still supported on plans that already include Google Workspace allotment — your existing plan, billing, and support are unaffected, and Google Workspace mailboxes continue to be billed as before. New or additional Google Workspace allotment is not currently available to purchase, so all new mailbox purchases are SMTP mailboxes. If you need Google Workspace mailboxes beyond what your plan includes, contact us in chat with the number you need and we'll confirm your options and timing. Full details: Google Workspace mailboxes: availability, deleting, changing the address, and the Admin mailbox.
Exact package sizes, prices, and domain allowances can change — the Packages & Add-ons page and our website show the current numbers; if the two differ, the website is current (see Why is the price in the app different from the price on our website?).
