Email filtering systems, such as Barracuda, can affect overall scores in the reporting section of Send drastically. These systems are designed to protect email software, such as a company's email system, from being corrupted by picking up certain email campaigns as spam. While this is usually an essential, helpful tool there can be rare cases when the filtering does not act as normal and can be a hindrance when you start analysing your campaigns. This article will give advice on how to detect email filtering systems and also offer different solutions on how to approach the situation before and after it has taken place.
What is email filtering?
An email filtering system blocks access to objectionable content and unauthorized internet applications (Spam). It does this by filtering content which it deems a threat to your computers security.
How do I detect it?
By looking at your reporting and seeing a contact with an abnormally high score, check to see whether the number of total clicks and number of total views are identical. If so this is a sign that an email filtering system has been activated and the email campaign has been registered as spam, and therefore is the reason that the score in reporting is massively affected. It is important to remember that the high number of clicks are usually just for the 'recipient web version from plain text'. The email filtering system interacts with the plain text version of the campaign and that is the link that is clicked.
What do I need to do?
One procedure that can help to minimalize the chance of email filtering systems affecting your campaigns is to always check for content that could be picked up as spam. For example, financial content has proved to be a trigger in many cases so when creating a campaign it is always important to keep this in mind. Alternatively you can ask the contacts receiving your campaign to complete whitelisting, or to contact the company designing these systems.
How do I filter out those recipients in custom reports?
Unfortunately there is no easy way to filter this data unless a cap is put on the score in the reporting section. The best course of action is to ask contacts to complete whitelisting, which has proved successful in many cases or to simply contact the email systems company support.
