Features

Enhanced Email Delivery with Certified IPs
Relay Service and Sender Address Rewriting
Secure Document Handling and Enforced TLS
Status Messages and Live Tracking
Dedicated IP
Email Live Search and Monitoring
Retarus Transactional Email service offers CSA-certified (Certified Senders Alliance) IPs ready to be used. Retarus also supports during the IP warm up phase (gradually increasing the volume of mail sent with a dedicated IP address).

The Destination Relay feature allows you to define a custom target mail server (or relay) instead of sending the email to the recipient domain

The rewriting of sender addresses for outgoing emails streamlines the implementation of company-internal policies when company-internal domains should not be used for external communication. We offer the option of automatically rewriting your envelope from-address for outbound emails so that any replies can be rerouted directly to a dedicated inbox.

Encrypt the files you want to attach to your outgoing emails. To ensure the best possible protection for your recipients, this service is offered together with our AntiVirus MultiScan.

Detailed monitoring can be used to check the status of a sent email in real time.

  • Status information via API callback (webhook) or non-delivery report (NDR)
  • Information about the delivery status, reason for undeliverability, blocked emails sent to recipients recorded in the suppression list, or open and click rates, etc.
  • Detailed information about each final SMTP status, e.g. recipient MTA, time stamp, operating system, email client, etc.
  • Automated integration of status information in business processes and applications
  • Simple master data maintenance (list hygiene), easier bounce and traffic management, better domain reputation
  • Live monitoring in the EAS Portal for tracking transmission jobs in real time

For volumes of more than 1,000,000 monthly emails, one or more sender domains can be allocated to a dedicated IP address. The email traffic from various applications, parents or subsidiaries can be differentiated.

Search for outbound emails based on time periods, message IDs, senders and recipients, and to obtain detailed status information of the past 45 days. Track emails in real time.

Recognize trend developments in the areas of delivery, soft/hard bounces and dropped messages, and initiate counter measures accordingly.
