Everything you need to send your server's outbound emails with high deliverability, securely and with full visibility.
No username or password required. Server IP addresses registered in the panel are automatically whitelisted — only connections from permitted IPs are accepted.
Every email sent through SmartHost is automatically aligned with SPF and signed with DKIM, minimising the risk of landing in spam folders.
All customers send from dedicated IP pools with no blacklist history. IP reputation is continuously monitored and protected.
Track the status of every email (delivered, rejected, deferred) in real time. Detailed SMTP log records are accessible from the web panel.
Undeliverable emails (hard bounce, soft bounce) are automatically classified and reported, making it easy to identify problematic addresses.
Transmission from your server to SmartHost and from SmartHost to destination servers is secured with mandatory TLS encryption. Full IPv4 and IPv6 support.
No MX record changes needed. Simply update your server's smarthost/relay setting and outbound emails instantly begin flowing through SmartHost.
Select the right package and complete your order. After activation, add the server IP addresses you want to whitelist from the panel.
