Send 100k cold emails a month and land in the inbox.
We build your sending infrastructure — Google & Outlook inboxes, SPF, DKIM, DMARC, warmup, and sending tool wiring. The same infrastructure everyone else uses — at $1.50/inbox, half the industry standard $3.00.

The math
What you'd pay, vs. what you actually pay.
Tell us your reach — we size the infrastructure and price it three ways. Google charges $7.27 per inbox. Most agencies mark it to $3.00. We charge $1.50.

The full cold-email stack. Nothing you have to do.
Every layer between you and the send button — handled. We don't sell you part of an infrastructure and call it complete.
01
Domain connection
You bring the domains — fresh, never-burned, owned by you. Pointed to your Cloudflare account; we manage DNS via API token. Use our generator for names. Need to consolidate? We'll move them to Cloudflare for you.
02
Inbox provisioning
Sender personas, profile pictures, backup codes, password rotation — all configured at creation.
Instantly, Smartlead, EmailBison — we connect your inboxes to the sending tool of your choice.
05
Health monitoring
Daily automated checks. We catch disconnections, suspensions, and reputation drops before you do.
06
Client dashboard
Live view of every inbox, credential, and connection. Reconnect or rotate without filing a ticket.
Operator quotes
What teams said after switching to InboxFlow.
Real operators, real volumes. The only thing we've changed is the price they pay for the same setup.
OMNIPOTENT PR
“
In PR, deliverability is the difference between a placement and a void. Before InboxFlow our pitches were dying in spam folders we didn't even know existed. They built 240 inboxes across 80 domains in 48 hours, consolidated everything onto our Cloudflare in a single weekend, and our reply rates tripled the same week we went live. We've stopped thinking about infrastructure entirely.

The process
From order to outbound in days, not weeks.
Four steps. The first is yours; the next three are ours.
01
Place your order
Tell us how many inboxes, Google or Outlook, and which domains you'll provide. We confirm cost, scope, and timeline before charging anything.
Pick the platform you send from — Instantly, Smartlead, EmailBison, or another. Share an API key and we wire your inboxes in.
Connected, authenticated, ready to send
04
You start sending
Inboxes are warmed up, connected, and monitored 24/7. We surface health alerts before campaigns are affected.
Daily checks · auto-alerts on disconnection
Honest terms
What you bring, and what we don't.
We charge near cost — which is only possible because we don't dress up the parts of the job that aren't ours. Two things to know before you order.
01 — You provide
Domains — brought by you, owned by you.
We don't buy or hold domains for clients. You register them on your own account, on your own card — then point them at Cloudflare, where we manage DNS via API. Your account, your token, your asset. Pull the keys back any time.
Must be brand new
No second-hand, expired, or previously-used domains. Reputation history follows the domain forever — we won't ship inboxes on a burned name.
DNS lives on Cloudflare
Doesn't matter where you bought them — Namecheap, Porkbun, GoDaddy, Squarespace. They get nameserver-pointed to your Cloudflare account so we can manage records via API.
We'll do the transfer for you
Got 200 domains scattered across registrars? Hand us your registrar credentials and a Cloudflare API token. We'll consolidate everything onto your Cloudflare in one pass.
You own the Cloudflare account
Always. We work through an API token you create and can revoke. Never our account, never our credentials — your control, end to end.
Need names? Use the generator.
Our domain generator suggests on-brand, deliverability-safe alts and TLDs in seconds.
Below 30 inboxes, the per-account setup overhead doesn't justify the rate we charge. We turn down small orders rather than mark them up. If you need fewer, we'll point you to a vendor who does that volume well.

Provenance
“We built InboxFlow because we couldn't find a vendor we trusted with our own outbound. So we became one — and decided to charge what it actually costs.”
