Inbox Warmup Explained

Before we send a single cold email, we spend 3+ weeks building your inbox reputation. Here's why this matters and how it works.

Why Warmup Matters

Email providers (Gmail, Outlook) judge senders by reputation. A brand-new inbox sending 100 cold emails on day 1 will get flagged as spam. A warmed inbox with a 90%+ reputation score lands in the primary inbox.

Skipping warmup is the #1 reason cold email campaigns fail before they start.

How We Warm Your Inboxes

Our warmup system:

Sends small volumes of emails between warmed accounts

These emails are automatically opened and replied to

This builds positive engagement signals

Volume increases gradually over 21–28 days

Reading Your Warmup Stats

On the Campaigns page, you'll see:

Avg Reputation — percentage score (85%+ = ready to send)
Progress bar — visual warmup completion
Est. Go-Live — projected date when inboxes hit threshold

When Are We Ready?

We require 85% average reputation across all inboxes before activating your campaign. Most accounts reach this in 22–28 days.

You'll be notified automatically when your campaign goes live.
