---

Sendmux is a smart email proxy that sits between your MailWizz instance and your SMTP providers (Gmail, Outlook, or any custom SMTP). It handles routing, rate limiting, failover, and delivery tracking — so you can focus on sending campaigns.

• One API endpoint routes to all your configured providers automatically
• Smart rate limiting randomizes sending patterns to look natural
• Automatic failover bypasses failed providers with zero downtime
• 100% delivery success — every email is reliably queued and handed off to your designated providers
• Bounce & complaint webhooks are processed automatically back into MailWizz
