B2B SaaS lead generation, built like infrastructure.
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.
No, because we never send from your primary domain. Outbound runs on separate dedicated domains and mailboxes, each warmed for around 14 days before a real campaign touches it, with per-inbox daily caps and rotation across the pool. Placement is tested weekly. Your main domain carries none of the sending risk, so support and sales email stays clean.
A 20-minute call. We tear down your current sequence, your ICP and your domain health, then tell you what's actually fixable.
