Break-Even & Migration Summary
By eliminating per-message CPM metered surcharges and switching to an enterprise flat-rate AutoSMTP dedicated cluster, your migration pays for itself in less than 18 days.
Stop Paying Extortionate Per-Email CPM Markups
Deploy private bare-metal SMTP clusters with zero send limits and flat pricing.
The Economics of Switching to Dedicated Infrastructure
Commercial SaaS ESPs charge punitive overage CPM fees that scale linearly with your email volume. Once an organization exceeds 500,000 emails per month, the “convenience” tax of cloud-hosted SaaS turns into a massive operational expense.
Metered vs. Flat-Rate
Cloud ESPs bill you per message sent. AutoSMTP clusters are dedicated instances with zero metered send restrictions—dispatch 1 million or 20 million messages for the same flat monthly rate.
Zero Arbitrary Account Freezes
Third-party ESP automated risk algorithms can freeze your account without warning during revenue-critical campaigns. Your private server is 100% under your ownership.
Full Configuration Control
Fine-tune PowerMTA/KumoMTA wire connection limits, backoff retry queues, DKIM selectors, and rDNS directly at the host level without artificial provider throttling.
