For agencies
The same setup, twelve times, without twelve afternoons.
Nothing about standing up a client’s sending domains is intellectually difficult. It is just long, fiddly, easy to get subtly wrong, and it repeats per client — the worst possible combination of properties for work a person does by hand.
Infrabox turns that repetition into a pipeline: domains registered, DNS connected, Google Workspace mailboxes provisioned through the same eight steps every time, and handed to whatever sequencer the campaign runs in.

The workflow
Onboarding a client, end to end.
Five things you do. The eight provisioning steps sit underneath step three and run without you.
- 01
A workspace per client
Keep each client's domains and mailboxes in their own workspace and switch between them. One account, separate estates, no spreadsheet mapping domains to logos.
- 02
Buy the domains
Registered through the platform and pointed at DNS we manage — the precondition for anything automatic happening afterwards, because the records have to be writable.
- 03
Ask for the mailboxes
Say how many on each domain. Every one runs the same eight provisioning steps, in the same order, without an Admin Console session from you.
- 04
Watch, rather than chase
The dashboard shows which of the eight steps each mailbox is on. A mailbox that is taking a while is legible instead of mysterious — the difference between a status update and an apology.
- 05
Hand off over SMTP
Point the client's sequencer, or yours, at the relay. No Google logins to share, no app passwords to store, nothing to rotate when a contractor rolls off.
03what exists
What exists for this
The parts of the product that are about running many estates.
Not a separate agency edition — the same product, with the pieces that matter once the count goes up.
- Multiple workspaces on one account. Separate a client’s domains and mailboxes from every other client’s, and move between them without signing out.
- Member roles. Team members are owner, admin or member, with billing permission held as a separate flag — so a strategist can see the estate without holding the card.
- Batch domain connection. Up to 250 domains connected in a batch by default, adjustable per account. Onboarding a client is not a hundred single clicks.
- One flat mailbox price. $3.79 per mailbox per month whether it is your fifth or your five-hundredth. No volume band to negotiate into, no seat minimum to grow towards.
- Credentials that are not secrets you hold. Sending credentials are issued by us and shown once. No shared Google password living in a document that outlives the engagement.
What we are not going to pretend
There is no client-facing white-label dashboard you can drop a logo into today, no automated client reporting, and no deliverability guarantee to put in a proposal. Google Workspace is the only mailbox platform on sale.
We would rather you found that out on this page than three weeks into an engagement.

Questions
The ones agencies actually ask.
Is there an agency plan or a volume discount?
There is no agency tier on the public price list and no volume band — $3.79 per mailbox per month is the price at every quantity. If your volume is large enough that you want a different commercial arrangement, tell us the shape of it rather than reading a number off a banner written to make you call anyway.
Can I resell this to my clients under my own brand?
There is a white-label partner arrangement, and it is a conversation rather than a self-serve signup — so it is not priced on this site. If that is what you are after, say so when you get in touch and we will talk about it properly instead of quoting you something generic.
Do my clients need their own logins?
Not for the infrastructure. Workspaces and member roles are how the estate is divided and who can see what; the mailboxes themselves are used through whatever sending tool the campaign runs in, over SMTP.
How long does onboarding a client actually take?
Your part is short — pick domains, say how many mailboxes. The provisioning run is not: the typical durations in our own progress model sum to roughly 7.25 hours per mailbox, and about five-sevenths of that is a single step waiting for Google to verify domain ownership. Plan client kickoffs around that rather than around a number a marketing page made up. Here is the breakdown.
How many mailboxes can I run per client?
The default allowance is 5 Google mailboxes per domain, raisable per account to 20, and each mailbox is capped at 2,000 messages a day to stay inside what Google allows. Capacity comes from more domains and more mailboxes, so the arithmetic is straightforward — the calculator will do it for you.
What happens when a client leaves?
The domains and mailboxes are assets on the account that holds them, and keeping each client in its own workspace is what makes that boundary clean. Mailboxes are billed per mailbox per month, so the bill follows the count when the count changes.
Do you handle the campaigns too?
No. Infrabox is the infrastructure underneath a sequencer — not a sequencer, and not an agency. You keep the tool you already run campaigns in; we make sure the domains and mailboxes it sends from were set up properly.
Weighing this against doing it in-house?
We wrote the comparison out honestly, including the cases where the other approach is the right one.
Tell us how many clients.
How many client estates, how many domains each, and which sequencer they run in. We will come back with a real total and a realistic timeline.
