SmartHost Mail Gateway

Don't Let Your Emails Land in Spam

Mail Gateway (SMTP Relay) allows you to send your emails through optimized relay servers with high reputation scores, rather than sending directly from your local server.

When your own server's IP reputation is low, your emails drop into spam folders in Gmail, Outlook, etc. Eliminate this problem entirely with SmartHost Mail Gateway.
