Preflight cold-email inbox checks — automated verification before sending

Preflight cold-email inbox checks — automated verification before sending targets a $6.0B = 5M sales teams × $1.2K ACV total addressable market with medium saturation and a year-over-year growth rate of 12% YoY — based on combined growth of email marketing automation and deliverability software market estimates (industry reports and vendor growth trends).
