Your sending volume and revenue impact suggest the Deliverability Foundation tier is the right starting point.

No obligations. Nada.

Annual revenue at risk is the total revenue lost because emails never reach their destination. Every email that lands in spam or goes missing is a missed conversion opportunity.

Annual Revenue at Risk = Monthly Sends × (1 − Inbox Rate) × Conversion Rate × Avg Order Value × 12

Monthly recovery potential is the incremental revenue you'd gain by reaching MailMonitor's guaranteed 90% inbox placement rate. If you're already at or above 90%, this is $0.

Monthly Recovery = Monthly Sends × max(0, 90% − Current Inbox Rate) × Conversion Rate × Avg Order Value

ROI calculation compares the revenue recovered at 90% inbox placement against the cost of the recommended MailMonitor tier. Net gain = revenue recovered minus MailMonitor investment.
