Reputation Management

Reputation management is a key feature for sending high performance and transactional emails

It’s about your reputation

Transactional emails for customer communication often result into large email volumes. These can only make way into recipients’ inbox if you are a trusted sender. Retarus is a leader in reputation management with its Transactional Email. It logically separates emails sent from your application from user-based email traffic and offers whitelisting for large ISPs with certification by the Certified Senders Alliance (CSA).

Retarus keeps your sender score high and ensures that the delivery rate is high too (inbox placement) by sending emails from a domain that belongs to you and you control. The sender address that the recipient sees is identical to the technical address, so that the recipient’s SPF and DKIM checks are always authentic.

The sender address is also important for IP routing by sender domain. You can use multiple sender domains to send your traffic from different IP addresses, which drastically reduces the impact of possible blacklisting.

Bounce management included

Another key element to protecting your reputation as a sender are Retarus suppression lists. They cache erroneous recipient email addresses when sending bulk emails and block resend attempts prior to sending. And you learn which recipients cannot be reached and why, so you can maintain your distribution list and ensure that you do not generate any unnecessary bounces.

In addition to comprehensive API functions, the Retarus EAS Portal (Enterprise Administration Services Portal) displays tracking and status information of messages at all times. These can be analyzed, so you can quickly clean up and optimize master data.
