01 The Problem

Most Teams Waste Weeks On Infrastructure Before Sending A Single Email.

Cold email infrastructure is deceptively complex. Between domain reputation, DNS configuration, inbox warming, and sequencer integration, most teams spend more time fighting their tools than actually running campaigns. That is time and money you cannot get back.

Spending hours on DNS records, SPF, DKIM, and DMARC setup

Inboxes landing in spam before you even start warming

Shared IP pools destroying your sender reputation

Waiting 4 to 6 weeks for inboxes to warm up properly

Support tickets that go unanswered for days

Paying premium prices for mediocre deliverability

02 Features

Everything You Need To Send At Scale. Nothing You Do Not.

ScaledInboxes handles the entire infrastructure stack so your team can focus on what actually drives revenue: great copy, sharp targeting, and compelling offers.

Enterprise Grade DNS

SPF, DKIM, and DMARC configured correctly from day one. No guessing and no trial and error. Your sender reputation is protected by default.

24 To 72 Hour Target Setup

From order to sending, we handle domain registration, DNS, inbox creation, and full configuration. Standard setups target 24 to 72 hours once requirements are clear.

Sequencer Setup Included

We do not just hand you credentials. We connect your inboxes directly into Instantly, Smartlead, Apollo, and more so you can launch immediately.

Built For Scale

Whether you need 5 inboxes or 500, the infrastructure scales with your outbound operation. No bottlenecks and no limits.

Works With Everything

Compatible with Instantly, Smartlead, Apollo, Lemlist, Outreach, Salesloft, and every major sequencer. Plug in and go.

WhatsApp Support

Dedicated WhatsApp support with operators who understand cold email infrastructure and can help with setup, troubleshooting, and launch questions.

03 How It Works

From Order To Sending In Four Simple Steps.

We handle every step of the setup. You just show up and send.

01

Choose Your Plan

Select Outlook domains at $50/mo or Google inboxes at $3.50 each. Minimum 5 Google inboxes, no long term contracts, and the ability to scale up or down anytime.

02

We Configure Everything

Our team registers your domains, configures SPF, DKIM, and DMARC, and creates your inboxes fully set up and ready within the agreed setup window.

03

We Set Up Your Sequencer

We connect your inboxes directly into your sequencer so you can launch immediately instead of wrestling with credentials and DNS records.

04

Launch Your Campaign

Your inboxes are live, your DNS is clean, and your sequencer is loaded. All that is left is writing great emails and hitting send.

Infrastructure

The Infrastructure Your Campaigns Actually Deserve.

Most inbox providers give you a login and a prayer. ScaledInboxes gives you a fully configured sending environment with a team that stays on top of it.

What exactly is included in the $50/month Outlook plan?

How does the Google Workspace inbox pricing work?

Google Workspace inboxes are $3.50 per inbox per month with a minimum order of 5 inboxes. You order exactly what you need and can scale up as campaign volume grows.

What does fully configured actually mean?

Fully configured means domains, inboxes, SPF, DKIM, DMARC, SMTP credentials, and sequencer connection are handled before launch. You should not need to touch DNS manually.

How long does setup take?

The target setup window is 24 to 72 hours after order details are clear. Larger or custom infrastructure can take longer depending on volume and domain requirements.
