About

Primeforge is a cold email infrastructure platform built to provision fully compliant Google Workspace and Microsoft 365 mailboxes, specifically optimized for high-deliverability outbound outreach. It automates the complex technical setup required for cold email, including SPF, DKIM, and DMARC configuration, domain authentication, and DNS management, allowing teams to deploy ready-to-send mailboxes in about 30 minutes without manual IT work. It uses trusted email service providers and US-based IP infrastructure to improve inbox placement and reduce the risk of messages landing in spam folders. Primeforge supports bulk domain and mailbox management, workspace organization, and compatibility with virtually any outreach software, enabling agencies and sales teams to scale multi-domain campaigns efficiently. It also includes automated account configuration, profile personalization, and best-practice implementation to maintain sender reputation and stable performance.

About

The sendmail Sentrion platform is specifically designed for large, complex environments, but we make a subset of that solution available as an open-source offering. Sentrion is not for everyone, but if you are using open source email for a large complex environment and need an enterprise platform that will enable your messaging roadmap for years to come (virtualization, consolidation, cloud migration, etc.). The Domain Keys Identified Mail (DKIM) Internet standard enables email senders to digitally sign their messages so that receivers can verify that those messages have not been forged. The DKIM sender authentication scheme allows the recipient of a message to confirm a message originated with the sender’s domain and that the message content has not been altered. A cryptography-based solution, DKIM provides businesses an industry-standard method for mitigating email fraud and protecting an organization’s brand and reputation at a relatively low implementation cost.
