Cold Email Inboxes Built for Deliverability and Scale

Cold outreach does not fail because of messaging alone. In most cases, it fails due to weak inbox infrastructure. Poor setup, rushed scaling, or unreliable providers lead to spam placement, inbox shutdowns, and wasted effort.

Launch high-performing cold outreach with US-IP Google Workspace inboxes that achieve flawless deliverability.

Endy Inboxes provides cold email inboxes designed specifically for outreach, long-term deliverability, and responsible scale. Instead of disposable inboxes, we focus on building stable email infrastructure that outbound teams can rely on.

Why Cold Email Infrastructure Matters More Than Tools

Most teams focus on tools first. Sequences, automation, and copy get all the attention. Infrastructure is often treated as an afterthought.

That’s where problems begin.

Without proper outbound email infrastructure, even the best campaigns struggle. Common issues include:

Emails landing in spam despite low daily volume

Accounts getting flagged or suspended

Domains burning quickly after launch

What Makes Cold Email Inboxes Fail at Scale

Cold outreach introduces patterns that inbox providers monitor closely. When inboxes are created without outreach in mind, risk increases quickly.

Typical failure points include:

☞ Generic inbox provisioning with no outreach context

☞ Missing or incorrect DNS authentication

☞ No warm-up strategy before sending

☞ Shared or unmanaged IP environments

☞ Aggressive sending volumes too early

Cheap or bulk providers often sell cold email mailboxes without accounting for these risks. The result is short-lived inboxes and inconsistent results.

Is Google Workspace Good for Cold Email?

This is a common and valid question: is Google Workspace good for cold email?

The answer is yes, when it is configured correctly and used responsibly. Google Workspace is widely trusted, but it enforces strict quality signals. Inboxes that are rushed, misconfigured, or abused are quickly flagged.

That’s why our focus is on:

Proper setup before sending

Gradual warm-up rather than immediate volume

Clear guidance on safe outreach practices

When handled correctly, Google Workspace can support cold outreach effectively.

Endy Inboxes vs Typical Google Workspace Resellers

Sending reputation is influenced by multiple factors, including IP environment. Our setup supports US IP Google Workspace inboxes to align with common outreach geographies and reputation expectations.

This does not guarantee inbox placement, but it supports:

Cleaner sending reputation

Reduced regional mismatch signals

Better alignment with recipient inbox providers

IP alignment is one part of a broader deliverability strategy, not a standalone fix.

How Much Does Cold Email Infrastructure Cost?

Another frequent question is how much does cold email infrastructure cost.

Pricing varies based on:

☞ Number of inboxes required

☞ Setup complexity

☞ Warm-up requirements

☞ Ongoing infrastructure support

Rather than offering one-size-fits-all pricing, we focus on building the right infrastructure for your scale and use case. This avoids overpaying for inboxes you don’t need or under-building infrastructure that fails later.
