Overview

What is Mailscale?

Mailscale automates the creation of cold email inboxes for agencies and B2B companies. It produces ready-to-send accounts that integrate with standard outreach platforms. Teams use it to scale prospecting while keeping deliverability high.

Mailscale builds company email accounts in bulk so outbound teams can launch campaigns faster. The platform generates up to 50 inboxes in under a minute and reduces per-inbox costs by roughly 80 percent compared to standard providers. It handles domain management and deliverability configuration automatically, removing the need for manual DNS or SPF work. Each account connects via IMAP and SMTP to popular sending tools such as Instantly or Smartlead. The service is built strictly for cold outreach to new prospects, not for transactional or subscriber-based messaging. Users receive a CSV export that imports directly into their sending platform within minutes.
