Question 1

What is a cold email infrastructure partner?

Accepted Answer

A cold email infrastructure partner like port587 designs, builds, and operates the technical systems behind B2B outbound email: dedicated sending domains, mailbox setup, DNS authentication (SPF, DKIM, DMARC), warmup schedules, deliverability monitoring, and reputation management. The goal is to ensure cold emails reliably reach prospects' inboxes.

Question 2

How much does cold email infrastructure cost?

Accepted Answer

Cold email infrastructure pricing varies by volume and complexity. port587 offers tiered plans based on sending volume, number of domains, and scope of management. Typical engagements range from foundational infrastructure setup to full done-for-you outbound operations including lead generation and campaign management.

Question 3

How is port587 different from Apollo or Instantly?

Accepted Answer

Apollo and Instantly are software platforms you operate yourself. port587 is an infrastructure partner that builds and runs the underlying systems for you: domains, mailboxes, deliverability, lead sourcing, and campaign operations. You focus on strategy and closing; we handle the technical execution.
