Cold email infrastructure for Apollo teams

Apollo is powerful for sequencing and data. But deliverability still depends on your domains, DNS, and mailboxes. We fix the layer Apollo can't control.

Who this is for

Teams using Apollo.io for prospecting and sequencing who want better inbox placement.

Typical sending volume

5k to 100k+ emails per month through Apollo sequences.

Tool stack reality

Apollo as primary outbound tool, often connected to HubSpot or Salesforce as CRM.

Pain pattern

  • Apollo shows emails as 'sent' but open rates suggest most are hitting spam.
  • Using Apollo's built-in mailbox connections without proper domain setup.
  • No separation between prospecting experiments and core outbound campaigns.
  • Hard to tell whether bad results are Apollo's fault or an infrastructure problem.

What we actually run

  • Dedicated sending domains designed to work with Apollo's sending architecture.
  • DNS authentication (SPF, DKIM, DMARC) tuned for Apollo's mailbox requirements.
  • Warmup schedules that account for Apollo's daily sending caps and rotation.
  • Monitoring that shows inbox placement independently of Apollo's built-in metrics.

Typical outcome

Infra-first
  • Independent inbox placement scores above 80% (not just Apollo's 'sent' metric).
  • Reply rates improving as infrastructure issues are resolved.
  • Fewer domain burns and reputation incidents.

We'll map your current infra, design a safe topology, and give you a concrete sending plan for the next 90 days.
