RealSender provides a secure email gateway designed to help businesses improve email delivery and protect their outbound communications. The service is presented as a way to move messages from being discarded or ignored toward successful acceptance and readership, with support available for delivery issues. RealSender offers sending through whitelisted IP addresses, allowing authorized senders to send email without the hassle of authentication, as well as dedicated IP addresses and a dedicated hostname.

It supports digitally signed email messages and email authentication standards including SPF and DKIM. Security settings are intended to help customers switch from their current mail server to RealSender, and authorized senders are protected by fail2ban. Additional controls can block harmful attachments, limit the number or size of messages, convert large attachments, and send a BCC copy of all outgoing email.

The site also invites visitors to explore a demo and contact the team. Together, these tools position RealSender as a practical service for managing email delivery and outbound email security
