Outbound infrastructure
Infrastructure that keeps outreach out of spam and off block lists.
AI makes it easy to send more, and easy to burn your domain. We set up and monitor the email and calling infrastructure underneath outbound, so your messages reach inboxes and your calls get answered.
Quick answer
What is outbound infrastructure?
Outbound infrastructure is the technical setup behind cold outreach: secondary sending domains, mailboxes, SPF, DKIM and DMARC authentication, warm-up, send limits, inbox-placement monitoring, and calling numbers with registered caller ID. It keeps outreach out of spam and protects your primary domain.
