Increasingly service providers are using third parties for email filtering leaving them no direct control over what is included/excluded or the ability to diagnose non-delivery of email.

CIS owns it's own filtering infrastructure, using 8 rejection systems spread over 4 paradigms/technologies. Our solution is used in over 30 domains containing thousands of email addresses jointly receiving over 12000 emails per day.

We don't just monitor our own infrastructure, but also delivery to and from other providers 24 x 7 x 365 to ensure we correct any issues before clients complain about missing emails.

MX Services

CIS offers an MX (Smart Mailer or eMail eXchange) service for clients who have their own email servers for final delivery.

We operate on the premise that no email should ever be lost, if we are not able to deliver an email to you we notify the sender.

We deliver email to you as quickly as possible, there is no unnecessary queuing or delays.

Additional features:

We will clean your inbound email of spam, and actively notify the sender at the SMTP level that the email will not be delivered.  This means that you do not need to have a spam/junk mail folder where emails go unresponded to (experience has taught us that many disagreements stem from the mis-use of Junk Mail folders).

CIS actively rejects email for users that the final (your) server does not accept email for by testing the address and caching the response.  This further ensures that if CIS accepts the email we will be able to get it to you.
