Outbound Tech Stack Cost Calculator
Running cold email in-house means stitching together a sending platform, mailboxes, domains, verification, and LinkedIn tooling, each billed separately, none of them showing you what a competing stack costs. Enter your volume below to see the real monthly DIY total.
Sending platform is a tiered estimate modeled on published volume-based pricing (Instantly Growth $37/mo up to ~5K sends, Hypergrowth $77.60/mo up to ~25K, higher tiers extrapolated above that). Mailboxes at $8.40/mailbox/mo (Google Workspace Business Starter, monthly billing). Domains at ~$1/mo each (~$12/yr registrar cost). Verification assumes each send is checked once against monthly volume, a simplification, real usage verifies a list, not every send. LinkedIn Sales Navigator Core at $119.99/seat/mo. Checked August 2026, all figures are published list prices and will drift, treat as directional.
