Ironmail is a complete bulk email platform. Not a wrapper around an API. Not a SaaS dashboard for someone else's servers.
Built on the industry-standard PHPMailer library. SMTP authentication, TLS/SSL encryption, DKIM signing support. Battle-tested across millions of email sends worldwide.
SMTP keepalive connections reduce overhead. Reuse authenticated sessions across batch sends. 30-second connection timeout with automatic reconnect on failure.
On failure: delay doubles (2x multiplier). On success streaks: delay gradually decreases (0.9x factor). 5 consecutive successes before speedup. Min 15s, max 120s adaptive range.
Each user gets isolated SMTP configurations, settings, and campaign history. User-scoped data with role-based access. Session management with secure login.
Add unlimited SMTP accounts. Gmail, Outlook, SendGrid, Amazon SES - mix and match providers. Toggle configs on/off without deletion.
Conservative 20-second base delay, batch pauses every 10 emails, and exponential backoff on failures. Your IPs stay clean.
Map CSV columns to {{variables}} in your email template. Dynamic subject lines, body content, and recipient data. Mass personalization at scale.
Server-Sent Events push every email status update in real time. Sent, failed, retrying, backoff, batch pause - all visible as they happen.
Every user gets their own settings, configs, and campaign data. SQL-scoped queries prevent cross-user data access. Session-based auth.
Built-in SMTP test endpoint. Verify connection, authentication, and sending capability before launching campaigns. Debug without guessing.
Ironmail is engineered for deliverability. The anti rate limit engine adapts in real time to SMTP responses. When a provider throttles you, the system backs off automatically. When things are clear, it speeds up. No manual tuning. No blacklists.
