Updated this week

We are excited to introduce Pre-Warmed Up Mailboxes—a game-changer for cold email outreach! These mailboxes are already warmed up and ready to use, helping you 10x your email deliverability while saving valuable time. Instead of spending weeks warming up new accounts, you can start sending emails immediately with optimized inbox placement. This guide will walk you through everything you need to know about pre-warmed mailboxes, including their benefits, how to purchase them, and why they are essential for successful cold outreach.

What Are Pre-Warmed Mailboxes?

Pre-warmed mailboxes are email accounts that have already gone through a gradual warm-up process before being delivered to you. Instead of starting with a cold mailbox that has no sending history, these mailboxes have been used for sending and receiving emails in a controlled manner, making them ready for immediate cold outreach without triggering spam filters.

Why Use Pre-Warmed Mailboxes for Cold Outreach?

1. Higher Deliverability & Inbox Placement

Cold outreach campaigns often struggle with emails landing in spam due to new or inactive mailboxes lacking sender reputation. Pre-warmed mailboxes have an established sending history, reducing the chances of emails getting flagged as spam.

2. Faster Campaign Launch

Without pre-warmed mailboxes, warming up a new mailbox takes weeks before you can send at full capacity. With pre-warmed mailboxes, you can start sending right away, skipping the slow ramp-up phase.

3. Stronger Sender Reputation

Email providers trust mailboxes that have a consistent sending history. Pre-warmed mailboxes already have a reputation, ensuring your emails are seen as legitimate and improving overall email deliverability.

4. Avoids Google & Microsoft Sending Limits

New mailboxes often have strict sending restrictions, which gradually increase over time. Pre-warmed mailboxes bypass these early limitations, allowing for higher sending volumes sooner.

5. No Need for Manual Warm-Up Tools

Normally, warming up an email requires third-party warm-up tools or manual email exchanges. Pre-warmed mailboxes come ready-to-use, saving time and effort.
