Introducing Warmbox
Securely Warm Up Your Inbox
Simple. Affordable. Secure.

Our Mission

To whoever who sends more more than 100 cold emails a day: We’re building an automated solution to warm up your inboxes. You already know that the warm up process is a pain. We do too. We’ve sent thousands of cold emails… So yeah, we get it. We’re creating Warmbox for one reason and one reason only: to keep your emails out of spam, and to thereby maximize your open rate.

Why is everyone so excited about Warmbox?

Because it’s the best and safest way to do what you do.

Automation

Our software automates the process of becoming an ideal, organic user. This vastly increases your outreach open rate.

Security

Unlike current solutions - we use a closed network of email addresses. This way your inbox is not being warmed up with a stranger’s inbox.

Killer Pricing

Simple and affordable. You pay per inbox (per month). That way, you determine a rate that fits your budget.
