You've done this before. An agency sprays 40,000 merge-tag emails from your primary domain, reports 'impressions', and six weeks later your sales team can't reach a customer without landing in spam. We run outbound like infrastructure: rotated domains, plain-text copy a human wrote, and a demo number you can forecast against.
Deliverability isn't a setting, it's a system. Dedicated domains, warmed mailboxes, per-inbox volume caps and rotation — so volume scales without the reputation cliff everyone hits in month three.
Firmographics are table stakes. We build lists on the signals that mean someone is actually in-market — stack changes, hiring, funding, expansion — then verify email, role and company before anything sends.
No HTML wrapper, no logo header, no 'I hope this email finds you well.' Short, specific, one ask. It looks like a note from a founder because that's exactly how it's written.
Our last agency burned the domain in eight weeks. One Zero rebuilt the whole stack and we've had 30+ demos a month since, without touching our primary domain.
A 20-minute call. We tear down your current sequence, your ICP and your domain health, then tell you what's actually fixable.
