Outbound email infrastructure engineering for the AI era. I design, build, and protect the sending systems behind GTM outbound — domains, mailboxes, authentication, warmup, and monitoring — and fix deliverability when it breaks.

About beltscrub.org
Mailflow Authority is an email infrastructure engineering service founded by Braedon in Portland, Oregon. It helps funded startups and B2B sales teams build, scale, and repair the systems behind outbound email, including campaigns sent by SDRs and AI agents. Rather than treating poor inbox placement as a copywriting issue, Mailflow Authority focuses on the technical causes: sender authentication, domain reputation, mailbox configuration, sending patterns, and monitoring.
Services begin with a one-time infrastructure audit, which reviews domains, authentication, mailboxes, sequencer settings, and reputation, then provides a prioritized action plan. Buildouts can include secondary sending domains, mailbox provisioning, SPF, DKIM and DMARC configuration, warmup, sequencer setup, monitoring, and a team runbook. Ongoing managed deliverability support covers reputation management, incident response, monitoring, and new domain provisioning. The service also offers free introductory calls and diagnosis, a deliverability checklist, and a revenue leakage calculator. Mailflow Authority works with platforms including Instantly, Smartlead, Apollo, Clay, Klaviyo, SendGrid, Outreach, and Lemlist. Its stated goal is to help email reach inboxes reliably through well-engineered infrastructure.
