If you want to improve your email marketing campaigns, one of the key factors that you should consider are anti-spam filters. In this article we explain how to adapt your campaigns to avoid falling into them.

Anti-spam filters are your main enemy in an email marketing campaign. These mechanisms are activated by detecting an email that they identify as unwanted. Then, instead of directing it to your inbox, they send it to your spam folder. In this way, the chances that you, as a receiver, get to read it are practically non-existent.

An email can be considered spam for many reasons. Among them are that the sender is unknown, that its content is advertising or not secure, that you have not requested its shipment or that it has been sent to a large number of recipients in block. When this happens, the digital marketing campaign in which we include that email gets a much lower reach than desired.

Who activates the filters against spam?

It is the Internet Service Providers (ISPs) that introduce obstacles to prevent email owners from being victims of spammers. For this they establish a series of filters that hinder this type of unwanted shipments. But at the same time, these can also harm you as a digital marketing professional by increasing difficulties in getting your email marketing campaigns to the recipients.
